RAYCHEM EPKT PAPER 22KV 3C HEATSHRINK TERMINATIONS INDOOR
Description
Over the last three decades, engineers in utilities and industry around the world have specified million’s of Raychem cable terminations at distribution voltages up to 36kV. Raychem terminations have become identified with reliability because of their unparalleled long-term performance – where it really counts – in the field. Today there are many changes influencing the distribution of power at medium voltages. For example, the transition to new types of polymeric cable, distribution at higher voltages, and the widespread usage of compact switchgear. Anticipating these industry changes, we have continued to extend and improve the product range, based on the extensive experience both in the field and at our outdoor test sites in polluted and desert environments. Now these developments are incorporated in a new generation of Raychem heat-shrinkable cable terminations, that are even easier to select and install, without compromising the reliability of proven materials technology. The improved system is simple to use, because the basic termination components and installation steps are the same – even if your network operates with voltages of 7.2 to 36kV; if you use 12kV belted paper cable and 24kV water-blocked single core polymeric cable; whether you make equipment connections in a cable box or in compact switchgear. Let’s review the main advantages of the improved system:
Universal Selection Procedure
• Simplified selection table allows quick selection based on conductor cross section and voltage class for either polymeric or MIND paper insulated cables (For MI draining oil cables, contact your local representative)
• Simple modification codes permit easy specification of optional accessory kits
• Enhanced range-taking ability means that one kit fits more conductor sizes, reducing stocking requirements
• Unlimited shelf life allows stocking of economic quantities without product spoilage
Simplified Cable Preparation
• Improved treatment of screen cut back is compatible with all state of the art screen removal techniques
• No tapering of insulation required
• No polishing of polymeric insulation surface
• No special preparation of sectored, or eccentric conductors, or of cable that is curved after unreeling from the cable drum
• Cable preparation steps are similar to those for Raychem joints
