5 FOREWORD This volume is one in a series of five volumes, which together, form the Horizon Power Distribution Design Manual. The DDM is intended to be a comprehensive reference manual for distribution design work carried out by professional engineers and technical support staff. The five volumes are: Volume 1: Quality of Electricity Supply Volume 2: Low Voltage Aerial Bundled Cable Volume 3: Supply to Large Customer Installations Volume 4: Underground Residential Distribution (URD) Volume 5: Overhead Bare Conductor Distribution The DDM will also serve to initiate "newcomers" to distribution work in Horizon Power without them having to start from scratch. It serves to establish "standards" for design work to ensure that we get the best value from our facilities - not only in terms of initial cost, but also in terms of component availability, length of service life and cost-effective maintenance. In addition to this, the DDM will also serve as a teaching aid for courses run by Horizon Power. This volume describes the engineering process involved in designing and providing electricity supplies using bare overhead conductor. It describes the design process in detail, making use of standardised design information for use with routine work. Document Title: Distribution Design Manual Page 5 of 23 Print Date 4/05/2017
6 1 INTRODUCTION Low Voltage Aerial Bundled Cable (LV ) is a mains cable consisting of four cores twisted together to form a bundle. Each core comprises a cross-linked polyethylene (XLPE) insulated compacted aluminium conductor. The cable is supported on intermediate and strain poles with easy to install mechanical fittings. Electrical connections are made by the use of Insulation Piercing Connectors (IPC). 1.1 Advantages of LV Improved Reliability Insulated conductors eliminate the problem of clashing conductors which is a major cause of power outages during storm conditions Improved Safety for Employees Insulated conductors and fully insulated fittings virtually eliminates the possibility of making contact with live equipment thus significantly improving employee safety in comparison to bare conductor networks Reduced Bushfire Risk Insulated conductors eliminate the conductor clashing issues associated with bare conductors during windy weather. The reduced bushfire risk improves public safety and enhances Horizon Power's public image Reduced Maintenance Insulated conductors and fully insulated fittings eliminate the need for crossarms, insulators or wire ties. Maintenance is reduced and clearance to structures and over roadways is also reduced Reduced Initial Cost LV installations do not require equipment such as cross arms, insulators, wire ties thus reducing the initial installation cost and installation time Disadvantages of LV Prone to Bushfire Damage LV has XLPE insulation material that can be damaged during a bushfire when subject to high temperatures. This may initiate a fault on the line and the cable may require to be replaced Bird Damage There is evidence that parrots have caused insulation damage to the XLPE insulation. This issue has been progressively addressed over time with improvements in XLPE material technology. Document Title: Distribution Design Manual Page 6 of 23 Print Date 4/05/2017
7 2 APPLICATION OF LV 2.1 Application Low Voltage Aerial Bundled Cable (LV ) is an insulated overhead system that is a superior alternative to a bare wire system, to provide low voltage electricity services in areas where the mandatory underground residential distribution (URD) policy does not apply. Horizon Power's low voltage distribution system is a four wire (three phase and neutral) system. It is Horizon Power s policy that all new subdivisions are provided with an underground electricity supply. LV systems are considered when underground power is technically unsuitable or uneconomic for: 1) New electricity overhead extensions; 2) Replacement of existing electricity overhead networks; and 3) Where requested by the relevant local authority. 2.2 Upgrading Existing Electricity Overhead Networks Where existing networks are deemed by Horizon Power to be technically inadequate due to age, load growth, chronic vegetation interference problems or other valid reasons, consideration is given to converting the network to an underground installation. To reduce their tree control costs, local authorities may request Horizon Power to convert existing open wire networks to LV. Conversion to underground is Horizon Power's first preference at all times, but due to cost considerations the option of converting to LV should be considered, particularly when local authorities are involved. 2.3 Street Light Services Street Lights are generally installed at the local authority's request. Street lights supplied by LV will be provided with individual PE cell control. There is no separate wire available for street light control because LV is a four wire system.

8 3 LV EQUIPMENT 3.1 Cable Specialised equipment and fittings are used in the LV system. The following sections show the approved standard equipment used by Horizon Power in its LV system. Only approved standard equipment shall be used Mechanical Data Horizon Power presently uses two cable sizes in the LV system: 1) 95 mm 2 2) 150 mm 2 The mechanical characteristics of the cables are shown in Table 3-1. Table 3-1 LV Mechanical Data Number and Area Dia. Mass of Cable Min. Breaking Load Modulus of Elasticity αα Coeff. of Linear Thermal Expansion Minimum Bending Radius (mm) (mm 2 ) (mm) (kg/m) (kn) (GPa) (10-6 / C) Individual Core Cable Notes: 1) As the cable construction is four cores twisted together, it is important that on completion of each run, phasing out is performed. 2) Each core has a unique number and ribbing. 3) Care must be taken when joining LV to open wire overhead conductors to ensure that the correct conductors are connected together Core Numbering and Ribbing Each LV core is numbered and has ribbing on the surface of the insulating material to distinguish the three separate phases and the neutral core. The numbering and ribbing system used is as follows: 1) Red Phase Number "1" embossed on core, one rib. 2) White Phase Number "2" embossed on core, two ribs. Document Title: Distribution Design Manual Page 8 of 23 Print Date 4/05/2017
9 3) Blue Phase Number "3" embossed on core, three ribs. 4) Neutral No numbers embossed, fully ribbed (ribs spaced evenly on core). The sequence of the phasing, as viewed from beyond the cable end, at the start of the cable drum or at the end of the cable drum is as shown in Figure 3-1. Figure 3-1: Phasing of LV Document Title: Distribution Design Manual Page 9 of 23 Print Date 4/05/2017
10 3.2 Insulation Piercing Connectors As mentioned in the Introduction, the LV system is a totally insulated system. Mains and service connections are facilitated through the use of Insulation Piercing Connectors (IPC). There are two main types of IPCs used by Horizon Power: 1) Mains IPC; and 2) Service IPC 3.3 Fuse Switches Horizon Power uses two types of fuse-switches to isolate sections of the LV system. The fuse switches are load break, fault make switches with facilities to connect DIN type LV HRC fuse cartridges or solid links instead. 400 amp switch disconnector suitable for both 95 and 150 mm 2 cables is normally used immediately under transformers and are fitted with 315 A or 200 A fuse cartridges or at "T -off' points on the LV system (fitted with either fuses or solid links, for normally open points). 3.4 Circuit Breakers To protect single insulated customer "run-outs", Horizon Power uses circuit breakers mounted at the pole, in suitable boxes. Both three pole and single pole circuit breakers are used have a current rating of 50 A, and are fault rated at 6 ka. 3.5 Cable Supports Support Fittings The LV system is suspended from each pole via the use of several items of basic mechanical suspension equipment, which are: 1) Universal Bracket This is mounted on every pole and facilitates the connection of: a) stringing blocks/rollers (during stringing); b) suspensions clamps; c) circuit breaker boxes; and d) street light stand-off brackets. 2) Suspension Clamp The suspension clamp "holds up" the LV conductor on to the universal bracket. The cable is held within the insulated insert of the clamp. Only one suspension clamp per pole is necessary for intermediate pole angles from 0 to 25. Document Title: Distribution Design Manual Page 10 of 23 Print Date 4/05/2017
11 3) Double Suspension Clamp Yoke This yoke is used to mount two suspension clamps on one universal bracket. Two suspension clamps are needed for intermediate pole angles of 26 to 50. 4) Strain Clamp The strain clamp is used to terminate the LV conductor onto a pole (using a universal bracket). The cores are fed into the holes in the clamp which is then tightened and prevents the cores from slipping Other Mechanical Fittings Other fittings used in the LV system include: a) Street Light Brackets; b) Circuit Breaker Box Mounting Bracket; c) Fuse Switch Mounting Bracket; and d) Various Facade Mounting Brackets. 3.6 Cable Failure Mechanism LV cable failure mechanism is as follows: a) First element to fail should be the suspension support by failure of the suspension clamp or the pole hardware supporting the suspension clamp. The cable should not be allowed to slip through the suspension clamp as this causes insulation damage, especially if an insulation piercing connector is fitted near the support. b) Second element to fail should be mains and service tee connections to minimise the number of live cables lying on the ground c) Third element to fail should be the pole hardware supporting the strain clamp d) Final elements to fail are: pole footing failure; cable failure; and pole failure, in that order.

12 4 FACADE MOUNTING OF LV 4.1 Façade Application The mounting of LV on the facades of commercial buildings or terraced houses can be an obvious benefit in areas of particular architectural or historic significance. Facade mounted LV is particularly suited for streets with buildings located in-line with each other, and separated occasionally by narrow laneways. Mounted on both sides of the street, this method removes the need for a pole line, service poles and service cables strung across the street which can at times be rather obtrusive. Facade mounting of LV may also be an economically attractive option to local councils looking into the undergrounding of existing bare overhead mains to "beautify" or to "improve the look of' prominent streetscapes or shopping precincts. In most installations, it is likely that the facade mounted LV would be hardly noticeable from the street and could be even less detectable if it is painted over (e.g. when the facade itself is repainted). 4.2 Advantages of Façade Mounting The advantages of facade mounted LV includes: a) Enhanced appearance of the streetscape; b) Virtually no disruption during construction; and c) More reliable electricity supply to property and perceived better value by removal of aerial services which are prone to being hit by tall vehicles. 4.3 Factors to be considered when Facade Mounting The following notes should be useful when considering façade mounting: a) Both 95 mm 2 and 150 mm 2 LV are suitable for facade mounting. b) Non-tensioned construction is to be used in most installations. c) Strain clamps should be used to terminate the cable for all runs over 10 m. In-line strains are to be used so that no run between strain clamps is more than 60 m. Intermediate wall supports should be spaced at every 500 mm to 700 mm intervals. d) Tensioned construction is seldom used but is applicable where the façade cable crosses over laneways or other similar situations. An everyday tension of 1.4 kn is recommended for 4 x 95 mm 2. Tensions for other sizes should be chosen to give an equivalent sag to this. e) Window openings shall be avoided. f) Paralleling of the LV to supply large commercial customers is possible with some facade fittings. g) Steel street lighting columns shall be supplied via underground cable. h) Consumers' mains are not to be altered. This could cause deteriorated cable insulation to fail, requiring expensive replacement. Document Title: Distribution Design Manual Page 12 of 23 Print Date 4/05/2017
13 5 DESIGN OF LV LINES The design process and the design principles are similar to those advocated in Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ). The relevant sections of that document that are applicable to design and any additional aspects that need to be considered are included in this section. 5.1 Design Process Refer to Section 2 of the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ). 5.2 Design Principles Refer to Section 3 of the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ). 5.3 Support Design and Stays Refer to Sections 4 and 5 of the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ). 5.4 LV Cables Sag and Tension Calculations The mathematical formula which relates sag to tension is: S = ω L 2 8 T Where S = mid span sag ω = conductor weight (N/m 2 ) L = horizontal span length (m) T = conductor tension (N) Factors that affect conductor tension are: 1) Temperature increase will result in decrease in tension and increase in sag 2) Wind increase will result in increase in tension 3) Age sag may increase over time due to creep 4) Pole movement stay relaxation may reduce tension and increase sag Tension Limits Under the limit state load conditions specified in Table 5.1, the tension in a conductor must not exceed 28% of its ultimate strength.

For 200 kva transformers, 150 mm 2 LV is used instead. Document Title: Distribution Design Manual Page 14 of 23 Print Date 4/05/2017
15 5.6 LV Conductor Selection Guidelines The size of the LV conductor is chosen to ensure that all of the following criteria are satisfied: a) Voltage drops during peak network load times are within maximum allowable limits b) Conductor current carrying capacity is adequate for maximum load currents c) Conductor impedance satisfying the LV fuse/protection requirements (so that at times of fault at the end of the feeder, the fault current will be large enough to be "seen" by the LV fuse and hence, cleared in time to prevent damage to the conductor). 5.7 Spacing Requirements Clearance from Ground At a cable temperature of 75 C the clearance of the cable from ground should not be less than the following: Table 5.3 Cable Clearance from Ground Notes: Over locations not Over other than Over roads negotiable by roads vehicles 5.5 m 5.5 m 4.5 m 1. When calculating ground clearance a construction tolerance of 300 mm should be included for long bay lengths and 100 mm for short bay lengths (typically up to 55 m). 2. For the purpose of this clause, the term ground includes any unroofed elevated area accessible to plant or vehicles and the term over means across and along. 3. The above notes are based on vehicles with a maximum height of 4.6 m Clearance from Structures The clearance of a LV cable from any structure, building, post or line support other than in the line under consideration must not be less than stipulated in Table 5-4.

17 5.8 Vertical Spacing of Conductors of Different Circuits Refer to Section 8 Conductors in the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ). 5.9 Voltage Regulation Refer to Section 9 Voltage Regulation in the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ) LV Network Design Refer to Section 10 LV Network Design in the Distribution Design Manual Volume 5 Overhead Bare Conductor Distribution (HPC-5DC ) Design of Existing feeders Re-conductored to LV The design of an LV feeder has more design restrictions than that of a bare overhead feeder. These restrictions, such as fusing and the radial feeder requirements must be incorporated into the new design of the feeder. Furthermore, most existing bare overhead networks may not have been formally designed, so re-conductoring the feeder or a portion of the feeder to LV provides the opportunity to improve the overall design of the entire feeder. The effectiveness of the design will depend on the accuracy of the data used Information Required Before any design work commences, maps of the entire LV feeder must be obtained either from Horizon Power s GIS or from geo-schematic drawings. These maps should show the bare overhead conductor types, lengths, location of open points and other LV isolators and the number of customers supplied from each pole. Information on the distribution transformer should be obtained including kva rating, maximum or peak current flowing through the transformer, present tap setting and the primary side voltage (MV) LV Design A detailed LV network design must be carried out on the existing feeder. This can be done using Horizon Power's PC based LVDESIGN computer package. Effort expended in optimising the design of the LV networks would result in significant reductions in conductor costs and also improvements in the quality and reliability of the electricity supply provided.

18 6 LV FEEDER PROTECTION 6.1 Introduction Horizon Power uses LV High Rupturing Capacity (HRC) fuses in its LV networks, to protect against: three phase faults; phase to phase faults; and phase to earth faults. Fuses are installed on LV networks to prevent or to minimise the risk of: 1) danger to the public caused by exposed live conductors where the insulation has been damaged; 2) fires caused by uncleared faults; 3) thermal damage to the cable insulation and to the transformer; 4) annealing of the conductor; 5) mechanical damage to the cable due to electromagnetic forces caused by high fault currents. 6.2 LV Feeder Protection Principles The general philosophy behind LV protection is that: ''Any segment of LV installed within a network, existing or new, shall be protected using appropriately rated LV HRC fuses". This means that: a) For new LV only networks, the LV feeder shall be protected by LV fuses (in insulated fuse-switch units) installed immediately after the transformer. b) When LV is used to upgrade existing bare overhead "meshed" (or "ringed-in") systems, the original mesh must be broken (and provision for an inter-connectable "open point" installed) so that the whole LV network, albeit a hybrid LV -Bare Overhead system, is made radial. c) When LV is used to replace the conductor in the "backbone" portion of existing bare overhead networks (i.e. the portion of the LV network immediately after the transformer), then: I. If the existing network is "meshed" (or "ringed-in"), the mesh must be "broken up" (i.e. made "radial"); and II. LV fuses must be installed in insulated fuse switches installed immediately after the transformer Document Title: Distribution Design Manual Page 18 of 23 Print Date 4/05/2017
19 d) When LV is used to replace conductors in the periphery of existing bare overhead networks, then: I. If the portion of the network being replaced is "meshed" (or "ringed-in"), the mesh must be "broken up" (i.e. made "radial"); and II. LV fuses must be installed (in insulated fuse switch units) at the interfaces between the bare overhead conductors and the LV conductors. One of the fuse switch units shall be left in "normally open" position (assuming that the breaking of the mesh arrangement was effected at one of the ends of the LV segment). e) If LV is used to extend the existing open wire networks, then: I. LV fuses shall be installed at the interface between the bare overhead system and the LV system; and II. 6.3 LV Fuse Selection Criteria LV extension shall be constructed as a radial extension. The LV fuse/protection concept used in Horizon Power is based on the following assumption or "rule of thumb": For satisfactory protection, the prospective phase-to-earth fault current at the end of the LV feeder should be at least three (3) times the LV fuse current rating. 6.4 Prescribed Fuse Sizes (MV and LV) For LV networks, after the transformer size has been selected, the appropriate fuse sizes for both the MV and LV must be determined in accordance with Table 6-1. The table also shows the appropriate fuse-switch unit to be installed immediately after the transformer. 6.5 Maximum Lengths of LV Feeders Refer to Clause 7.5 in the Distribution Design Manual Volume 4 Underground Cable Distribution (HPC-5DC ). 6.6 What if the Maximum Allowable Length is Exceeded? Refer to Clause 7.6 in the Distribution Design Manual Volume 4 Underground Cable Distribution (HPC-5DC ). 6.7 Calculation of Fault Currents at End of LV Feeders Refer to Clause 7.7 in the Distribution Design Manual Volume 4 Underground Cable Distribution (HPC-5DC ). 6.8 Fault Current Ready Reckoner Refer to Clause 7.8 in the Distribution Design Manual Volume 4 Underground Cable Distribution (HPC-5DC ).
