2 Captrad supply a wide variety of GRP (Glass Reinforced plastic) Cable systems from Cable trays, Cable ladders to Fibrestruts. The majority of our Cable Systems are produced via the pultruded process. This process allows the use of different resin systems depending uponthe application. It also allows Captrad to offer continuity of service not only on the product set but on the reaction to orders as well, catering from small projects to large production runs. FRP Product Advantages HIGH STRENGTH Higher strength than structural steel on a weight to weight ratio. IMPACT RESISTANT Returns to original position without any permanent deflection or distortion. LIGHT WEIGHT FRP pultrusion is lightweight, on average 15 to 20% that of steel products CORROSION RESISTANT Pultruded products are not susceptible to rusting, pealing or flaking and are impervious to a broad range of corrosive elements. NON-CONDUCTIVE Glass reinforced pultrusions have low thermal conductivity and are non-conductive. ELECTRO-MAGNETIC TRANSPARENCY Pultruded products are transparent to radio waves, microwaves and other electromagnetic frequencies. FRP Product Advantages DIMENSIONAL STABILITY The coefficient of thermal expansion of pultruded products are marginally less than steel and aluminium. LOW TEMPERATURE FRP has excellent mechanical properties at low temperatures. FIRE RETARDANCY All products used in the construction of ladders and trays are manufactured in accordance with ASTM-E84 class 1 & BS476 part 7 class l and ll. Self extinguishing to UL94 V-0 under test procedure ASTM-D 635. ULTRAVIOLET STABILITY All pultruded products contain a Ultraviolet inhibitor, this is further complimented with an external surface veil. WEIGTH AND SHIPPING Our versatile system is light weight and can be flat pack to reduce expensive shipping costs. HALOGEN FREE Our products are Rated Zero Halogen to IEC Tel:

4 SPECIFICATION DATA GRP CABLE SYSTEMS 1. INTERNATIONAL STANDARDS Cable ladder and tray system should comply with the materials and fabrication requirements detailed below 6. LOADING REQUIREMENTS There are three working load classifications for FRP cable ladder based on (20 ) support spans with a minimum safety factor of FRP LADDER AND TRAY SYSTEM SHALL CONFORM TO: BS 476 part 7 class I BS 476 part 7 class II ASTM E84 class I BS 476 part 6 ASTM D635 Nema standard- FG-1 (latest edition) IEC LADDER SIZES Ladder Heights: 75, 100, 150mm. Ladder widths: 150 through to 900mm. Ladder lengths: 3m & 6m. Rung Spacing is 300mm (other sizes available) Radius of Fittings: 300mm is standard. 600 & 900 on request. Fittings shall be mitred type. No moulded or pressed fitting are acceptable as they would not comply with specification. All ladder rungs are perforated as standard. 4. RESIN SYSTEM ISO Polyester class ll halogen free code (PHF) ISO Polyester class l code (PCI) Vinyl ester code (VE) Our standard resin system is our (PHF) 5. CABLE TRAY SIZES Widths: 50, 100, 200 & 300mm. For sizes greater than 300mm contact CCS for combination options and loading data. Depths: 50 and 80mm respectively Tray covers are self locking and clip on type. All trays will be perforated at 300mm centres. Radius of Fittings: 250mm is standard. 7.

11 CHEMICAL EXPOSURE GUIDE The information compiled in this exposure chart is related to data collected from actual projects installed in the field. Temperatures used are neither minimum nor maximum but represents a cross section of test conditions. Some products may be suitable for higher temperatures but individual testing should be carried out prior to installation. Please make contact with CCS for any special applications you may have. RESIN SELECTION Isophthalic ISOFR Uses modified premium grade Isophthalic polyester resins. Fire retardant and complies with ASTM E 84 and ASTM D635 Vinyl ester VEFR Uses vinyl ester fire retardant resin and complies with ASTM E 84 and ASTM D635 Tel:
