24kV Cold Shrink Straight Cable Joint Kit – 3-Core XLPE Power Cable Connector

Product Overview

The WNRLN CSJ-24/3C-120 is a high-performance 24kV cold shrink straight cable joint kit engineered for 3-core XLPE insulated power cables with conductor sizes ranging from 70mm² to 120mm². Designed for medium voltage distribution networks, this joint kit provides reliable, long-term electrical and mechanical protection in underground, trench, and substation installations.

Key Features

  • True Cold Shrink Technology – One-piece EPDM rubber body pre-stretched on a removable spiral core. Simply pull out the core after positioning – no heat, no gas torch, no special tools required.
  • 24kV Rated Voltage – Designed and tested for 24kV (Um=25kV) medium voltage power distribution systems, meeting IEC 60502-4 standards.
  • 3-Core Straight Joint – Integrates three-phase conductor connection, insulation, shielding, and outer sealing in one compact assembly.
  • EPDM Rubber Insulation – Ethylene Propylene Diene Monomer provides excellent electrical insulation, UV resistance, ozone resistance, and thermal stability from -40°C to +90°C.
  • Wide Conductor Range – Compatible with 70mm² to 120mm² sector-shaped or round stranded copper/aluminum conductors.
  • Integrated Stress Control – Built-in geometric stress cones ensure uniform electric field distribution, eliminating partial discharge risks.
  • IP68 Waterproof Sealing – Triple-layer sealing system with silicone mastic tape and outer EPDM jacket provides complete moisture ingress protection for direct burial applications.
  • Fast Field Installation – Typical installation time under 45 minutes per joint for a trained crew, significantly faster than heat-shrink or resin-based alternatives.

Applications

  • Medium voltage underground distribution networks (24kV class)
  • Wind farm collector grid cable connections
  • Industrial plant MV power distribution
  • Utility substation cable interconnections
  • Cable repair and extension projects
  • Mining and tunnel power supply systems
