15kV Cold Shrink Cable Accessories

Pre-expanded silicone terminations and joints for 8.7/15kV MV networks. No heat, no open flame, installed by pulling the support core.

15kV cold shrink accessories cover 8.7/15kV medium-voltage cable terminations and straight joints for XLPE-insulated distribution and sub-transmission. Each part ships pre-expanded on a removable plastic core. On site you slide it over the prepared cable and pull the core; the rubber recovers by elastic memory and grips the jacket with constant radial pressure. There is no torch, no hot-air gun, and no skill-dependent heating step.

That matters on the jobs where these parts are actually used. Renewable collector systems, data-center MV switchrooms and urban utility spurs all share the same constraints: no open flame in confined spaces, inconsistent installer skill, and a hard requirement that the seal hold against moisture ingress for the life of the joint. The build integrates a stress-control layer and a factory-fitted seal, so the field outcome depends far less on who is holding the tool.

Technical specifications

Applications by industry

• 15kV outdoor and indoor terminations on XLPE distribution cable
• Wind-farm collector circuit cable joints and riser terminations
• Data-center MV switchgear and transformer feeder terminations
• Solar PV substation 15kV cable sealing and protection
• Utility and industrial plant medium-voltage spurs
• Rail and metro MV power cable joints in confined enclosures

Why cold shrink for 15kV MV distribution

At 15kV the failure mode is partial discharge at the stress concentration where the insulation screen ends. A cold-shrink termination carries a factory-formed stress-control geometry, so you are not relying on the installer to tape or mould it in the field. Against heat-shrink, the advantage is the absence of a heat source: in a cable trench, a packed switchroom or an explosive-atmosphere site, that removes a real hazard and a real skill variable. The trade is material cost and a tighter fit to the specified cable OD.

Stress control and installation review

Stress control is built into the tube, but the joint still depends on cable preparation. Confirm the insulation-screen cutoff length against the body, measure the cable outer diameter (not just the conductor size) for body selection, and check that the kit covers the full conductor range you stock. Verify the core pull direction and that no lubricant remains on the contact surfaces.

Inspection and traceability

We state the control plan with you. Batch traceability links the raw rubber lot to the finished part and the test record.

• First-article inspection (FAI) against your cable schedule
• In-process dimensional checks at every station
• Batch certificate of conformance (COA) on request
• Lot traceability to incoming material certificate
• AC withstand and partial-discharge testing available on request
