The Universal Medium Voltage Termination System for Polymeric and Paper Insulated Cables
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 36 kV. 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 experiece 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 net- work operates with voltages of 7.2 to 36 kV; if you use 12 kV belted paper cable and 24 kV water-blocked single core polymeric cable; whether you make equipment connections in a cable box or in compact switchgear.

Universal Selection Procedure

• Simplifield 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.

Simplifield 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

Simplified Installation

• Components are lightweight and non-shattering
• Clear instruction sheets
• Common installation procedure for polymeric and MIND paper cables
• Factory engineered kit permits rapid on-site installation
• No mechanical stress at insulation screen cutback
• Termination accommodates same bending radius as cable
• Visual confirmation of correct assembly sequence possible after installation
• Rain skirts can be installed to allow either top or bottom feed
• No soldering of earthing accessories required

Outstanding Long-Term Reliability

• Fully sealed against water ingress from the environment or from within the conductor strands
• Polymeric materials load cycle with the cable without mechanically stressing termination components and sealants
• Unsurpassed performance in polluted environments, proven over three decades.

Features:

• Universal termination family for 12-36 kV based on SCTM stress control technology
• All applications for polymeric and MIND paper on 1-core, 3-core, armoured and unarmoured cables
• Red non-tracking HVOT tubing provides excellent environmental protection
