2 MAGIC GEL RAYTECH has developed an insulating and sealing polymeric gel with fast cross linking at normal room temperature. The Magic Gel kit contains two bottles of fluid, a small mixing basin and a spoon. Specially designed with Health and Safety in mind and to eliminate detrimental effects on the environment, the fluids combine in equal quantities to provide a non-toxic, re-enterable cable jointing gel - ideal for filling enclosures, boxes and terminal blocks etc. It is most suitable for anti corrosion protection, insulating and sealing applications. The product: Is non-toxic and safe Is suitable for installations up to 1kV and 120 degrees Celcius Has a very high resistance to natural aging Cross-links within 10 minutes, ready to use No shelf life MAGIC JOINTS A range of self-sealing, straight through and 30 degree branch joints are also now available for copper and aluminium single, 2, 3 and 4 conductor cables. Polymer insulation is provided by Raytech s two fluid Magic Gel system and can be used in place of cast resin. Characteristics: Non-toxic Self-sealing polymer insulation For 0.6-1kV voltages Guarantees protection of higher than IP68 Can be used in place of cast resin joints Permanently flexible Low exothermic peaks SKY PLAST Flame-resistant 2-component plastic For enclosing and insulating electrical and non-electrical components Can be used in place of insulation tape, heat shrink insulation and resin Characteristics Non-toxic Insulating Plastic Permanently flexible and malleable Suitable for any thickness, size and profile Can be retrofit Good dielectric characteristics Cross-linkage in less than 5 minutes at room temperature Temperature-resistant from 190 C to 250 C 2 ISSUE 30

3 The importance of Flame Retardant Tube in LV applications cannot be underestimated, especially in the Heavy Wall range. Heavy Wall Tube is normally installed in confined spaces, including LV panels, switchgear, cable trays, and underground environments. Places where, if started, a fire could destroy valuable plant and equipment and possibly put lives at risk. The Flame Retardant Tube will self extinguish, prohibiting extensive electrical and fire damage to your valuable assets. The minimum shrink temperature of Heavy Wall Tube generally exceeds the melting temperature of the most common LV cable sheaths (predominately PVC and XLPE). Therefore, it is advantageous to minimise the cable s exposure to excessive heat, which could create long term degradation of the cable insulation. You don t want to compromise your cable insulation because you have applied excessive heat to your Heavy Wall Tube. This is why the appropriate shrink ratio of a minimum 3 to 1 is so important - to facilitate fast and accurate shrinkage so you don t compromise your cable. All heatshrink is not created equal. To ensure you are providing maximum protection of your vital asset infrastructure at highly competitive prices make sure you specify Flame Retardant Heat Shrink Tube for all your LV applications. Only LS Tube meets all the rigorous international standards mentioned above. Peace of mind at no extra cost. Future proof with LS Cable & System s flame retardant range. When next ordering heatshrink specify it s flame retardant and UV stable LS Tube.

4 PRODUCT SHOWCASE NOW AVAILABLE THROUGH OHUG SIEMENS ARRESTER RANGE M 12 OR 3/8 INCH STAINLESS STEEL STUD NUT, WASHER CLAMP END FITTING SILICONE, HOUSING, DIRECTLY MOLDED METAL OXIDE VARISTOR MOV GLASS COATING FRP RODS END FITTING NUT, WASHER M 12 OR 3/8 INCH STAINLESS STEEL STUD 3EK7 a top quality product The silicone rubber housing is molded directly onto the MOV blocks and the protection cage. It provides an excellent sealing system against moisture ingress and partial discharges. In addition, the MOV blocks are glass-collared to prevent aging. Highest quality materials. Silicone rubber is highly hydrophobic and maintains this ability to repel water and any deposits of pollution throughout its entire service life. This results in high tracking and erosion resistance. Furthermore, the silicone rubber housing is self-extinguishing and flame-retardant. These advantages provide maintenance free and reliable service life for 3EK7 arresters. Manufacturing plants are certified under ISO 9001 and ISO EK7 arresters have been type tested by an independent test laboratory. Secure and reliable design The 3EK7 series is based on a cage of pre-stressed fibre reinforced plastic rods for high mechanical strength, reducing the risk of internal components being ejected. In the extremely rare event of the resistors being overloaded, arcing cannot result in a build up of critical internal pressure, since the resistors are not enclosed in a sealed mechanical shell. Thus, the arc can escape through the silicone sheath, leaving the mechanical support structure of the enclosure unharmed. The cage is lightweight design and yet it offers excellent torsional, tensile and cantilever strength: Maximum working cantilever strength of 350 Nm. Silicone rubber is resistant to UV and ozone exposure as well as to all common organic and non-organic solvents and cleaning agents. Therefore, the 3EK7 is suitable for any environmental conditions of industrial areas as well as in desert or coastal regions. 3EK7 arresters are suitable for a temperature range from 55 C to +60 C. Application altitude up to 3600 m a.s.l. 3EK4 and 3EK7 arresters are now available. For data-sheets and specifications CALL 0800 GET OHUG 4 ISSUE 30

6 PRODUCT SHOWCASE OVER 10 MILLION COLD SHRINK TERMINATIONS AND JOINTS INSTALLED Ever since the installation of the first 3M Cold Shrink termination in 1972, 3M have been working hard to develop products that deliver market leading installation efficiencies and consistent reliability to their customers. 3M s termination products give contractors and clients alike the confidence they need in their power networks as both hard and soft failure costs become more and more critical. Much like 3M s range of cable jointing products, the nature of Cold Shrink ensures a constant radial pressure is applied to the cable. It is this concept, combined with a comprehensive factory testing programme and a simple installation process that makes Cold Shrink the preferred termination solution for both public and private network operators across the world. From listening to their customers and committing to sustained research and development, 3M can offer you an excellent choice in Cold Shrink product technology in terms of product cost and installation simplicity. THE SIMPLE APPLICATION OF A 3M COLD SHRINK CABLE TERMINATION Prepare the cable as normal and clean with 3M Cable Wipes Place the 3M Cold Shrink termination body over the cable end and position at the correct point on the cable Begin to remove the inner core, allowing the termination to shrink down onto the cable Once the inner core has been fully removed, the termination installation is complete! PREMIUM 3M COLD SHRINK TERMINATIONS - FULLY INTEGRATED :: QUICK TERM III (QT-III) Born out of our unparalleled experience in the development of Cold Shrink technology, this fully integrated premium cable termination offers the greatest simplicity and flexibility in 3M s range. 3M s premium termination covers a wide range of cable sizes and types as well as accommodating voltages up to 69kV. Shorter installation length enable this product to fit into a wide range of boxes and fewer installation steps mean there is less room for jointer error. STANDARD 3M COLD SHRINK TERMINATIONS - PART INTEGRATED :: QUICK TERM II (QT-II) 3M part integrated Cold Shrink termination offers a viable cost-based alternative to heat shrink cable terminating technology. Additional process steps to 3M s premium range (above) mean that comparative time savings are less but the benefits of not having to use heat or extra tooling still apply. This range covers many of the most common cable configurations and size ranges.
