1 R RICS Insulated adapter termination system for SF 6 -insulated switchgear up to 24 kv

2 RICS Insulated adapter termination system for SF 6 -insulated switchgear up to 24 kv The increasing popularity of gas insulated switchgear called for the development of an appropriate connection to the bushing. Raychem has developed two systems for this purpose. The RICS insulating adapter (630 A) is compatible with all Raychem terminations and can thus be used to connect any type of cable, irrespective of whether it is paper or plastic insulated or has one or three cores. Simplified installation The compact design of the adapters and their clear cut profiles simplify installation. The electrical connection with the aid of a stud renders additional fastening systems unnecessary. Reliability Raychem has several decades of experience in the field of hermetically insulated termination systems for medium voltage applications. The adapters are water tight and guarantee uninterrupted operation, even under extreme environmental conditions with severe pollution. Tests The adapters conform to IEC 540, VDE 0278 and ANSI IEEE 386 specifications, as well as to the Raychem specification PPS The test requirements and results are summarized in Raychem Test Report PPR 1106, which is available on request. Different cables... New materials and new production methods have changed the face of medium voltage cables completely over the years, resulting in increased com-plexity. Paper and plastic insulated cables with one or three cores, round or sector shape, and many different types of shielding, water blocking systems, as well as varying insulation thickness can be found in today's networks....need different terminations... Catering for a wide range of cables with as few fittings as possible, while optimising the products for specific applications and maximising their reliability, was the logical consequence....or Raychem flexibility. Heat-shrink technology makes it possible to use a single size of fittings for a large number of cable cross sections and types. This universal technology not only reduces the requirement for jointer training but also the installation time, at the same time increasing the reliability, irrespectice of the type of cable used in the network.

3 RICS Insulated adapter termination system for SF 6 -insulated switchgear up to 24 kv The insulated adapter termination system provides perfect sealing, electrical insulation and an electrical connection between Raychem terminations and SF 6 -insulated switchgear up to 24 kv. Its lead-in insulator (630 A) conforms to DIN and ANSI IEEE 386. The cable box of the switchgear must be provided with suitable protection against electric shock. The insulating adapter is compatible with all Raychem terminations. Details of the terminations can be found in the cable accessories catalogue. T-adapter with or without surge arrester Design Thick walled insulator made of high quality elastomer with sealing face over the termination, bushing cone and plug. The electrical connection is made with a terminal stud and the cable lug of the termination. Two cable connection is possible. A special plug which allows cable testing without disconnecting the adapter is also offered. The design of the adapter for connecting the surge arrester is basically identical. The elastomer insulator has an additional lead-in duct for the surge arrester. Details of the surge arresters can be found in the brochure EPP Scope of supply (for three phases) Insulator, plug, terminal stud, small accessories and installation instructions. Straight adapter Design A thick walled, heat-shrinkable insulating sleeve provides a hermetic seal over the cone of the bushing and the termination. The adapter area is smoothed with a meltable filler strip. Scope of supply (for three phases) Heat-shrinkable insulating sleeving, filler strip, small accessories and installation instructions. Terminal stud and lug must be enclosed. T-adapter fitted with testing plug T-adapter for perpendicular connection of the termination to SF 6 -insulated switchgear Straight adapter for vertical connection of the termination to SF6-insulated switchgear T-adapter for perpendicular connection of termination and surge arrester to SF6-insulated switchgear

18 RSES/RSSS Screened Adaptor System 250 A, 24 kv Screened Straight Adaptors installed on SF 6 -switchgear. Raychem separable Screened Adaptors are designed to connect single-core polymeric cables to medium voltage equipment (transformers, switchgears, motors etc.) up to 24 kv. Made of crosslinked EPDM and protected with a minimum 3 mm moulded conductive shield connected to earth, Raychem deadbreak adaptors are suitable for both indoor and outdoor installations. Their wide application range allows a minimum number of bodies to cover several different cable cross-sections without the need for additional cable adaptors. The cut-back dimensions for all cable sizes are the same for RSSS and RSES. Raychem Screened Adaptors are equipped with a capacitive test point to ensure that the circuit is not energised before disconnection. The capacitive test point is protected by a conductive cap. A range of high strength bimetallic compression connectors tested to VDE 0220 are offered to connect both aluminium and copper conductor cables. After cable preparation and lubrication, the Raychem Screened Adaptors can simply be slid into place under virtually all conditions. A separable mounting system provides for an easy installation of the adaptor onto the bushing. In addition, Rayvolve tubing or heatshrink phase-marking sleeves are offered as an option, to provide a superior environmental seal. Screened Elbow Adaptors installed on outdoor SF 6 -transformer. Rayvolve Sealing Cold applied technology. Rayvolve is used in conjunction with a pressure sensitive mastic and is simply rolled into place. Thus a reliable moisture seal is achieved. The use of Rayvolve is particularly recommended for applications where a torch is unavailable or cannot be used. Heat-Shrinkable Sealing Moisture seal and phase marking. A reliable moisture can also be produced by using a mastic in conjunction with a heat-shrinkable sleeve. This solution has the additional advantage of providing phase marking. A standard torch carried by most jointers is used.

35 Energy Division GUROFLEX MV Cold-Pour Insulating Compound for Medium Voltage Applications Cold pour Safe to use No hazard classification Safe to use Excellent electrical properties Solves MV bulk-insulation problems Thoroughly tested to international performance standards Cures to a soft solid No leakage problems No topping-up or waiting time Immediate energisation Unaffected by water and traditional oil-based insulating compounds Insensitive to temperature Can be installed in cold or hot ambient conditions

36 GUROFLEX MV Cold-Pour Insulating Compound for Medium Voltage Applications GUROFLEX MV is ideal for filling cable boxes with complex phase metalwork or reduced clearances GUROFLEX MV is a two-component cold-pour insulating compound. After mixing and pouring it cures to a soft rubbery solid that will not melt or flow. It has excellent electrical characteristics and is suitable for a wide range of bulk insulation applications in medium voltage electrical power equipment. Because GUROFLEX MV is a coldpour material there are none of the serious hazards associated with the heating and pouring of conventional bitumen or oil-based insulating compounds. One of the outstanding advantages of its chemical make-up is that GUROFLEX MV is non-hazardous and does not contribute to environmental problems. The liquid components and mixed compound are not subject to any safety classification and no special measures are required for transportation, handling or disposal of waste. components, tapes or other applied insulation. GUROFLEX MV will also solve problems with air-clearance enclosures caused by hostile environmental conditions (persistent humidity, chemical pollution etc.). GUROFLEX MV has been thoroughly tested to the requirements of CEN- ELEC cable accessory performance standard HD (including the requirements of IEC ) for rated voltages up to 12 kv. Additional testing has included impulse voltage withstand at 125 kv. Performance qualification for applications at rated voltage 36 kv is in progress. GUROFLEX MV is compatible with all commonly-used terminations for MV polymeric and paper cables. It is also unaffected by the presence of oilbased residues of traditional hot-pour filling compounds. The curing reaction is not affected by the presence of water and the cured compound has very low moisture absorption. generate heat.
