24kV EPDM Cold Shrink T-Branch Cable Joint Kit – 3-Core XLPE Power Cable Branch Connector

Product Overview

The WNRLN CBJ-24/3C-120 is a specialized 24kV EPDM cold shrink T-branch cable joint kit engineered for creating reliable tee-off connections in 3-core XLPE insulated power cable networks. Designed for 70-120mm² conductors, this branch joint kit enables safe lateral feeder tap-off from main distribution lines without interrupting the through-circuit – essential for urban ring main units, industrial loop networks, and expanding MV infrastructure.

Key Features

  • T-Branch Configuration – Enables one main line to branch into two directions (through + lateral tap), forming a reliable T-connection in 3-core MV cable networks.
  • EPDM Rubber Insulation – Ethylene Propylene Diene Monomer provides excellent electrical insulation, mechanical resilience, and proven long-term aging resistance.
  • 24kV Rated Voltage – Designed for 24kV (Um=25kV) medium voltage distribution per IEC 60502-4 standards.
  • Cold Shrink Technology – Pre-stretched EPDM bodies on spiral cores eliminate the need for heat or gas torches during installation. Safe for confined spaces and gas-sensitive environments.
  • Integrated Stress Control – Each branch leg incorporates geometric stress cones ensuring uniform electric field distribution at the critical triple-point junction.
  • Wide Conductor Range – Handles 70-120mm² sector-shaped or round conductors on both main line and branch legs.
  • IP68 Waterproof – Multi-layer EPDM sealing system provides complete moisture protection for direct burial, duct, and trench installations.
  • Compact Footprint – The pre-molded T-body design minimizes excavation requirements compared to traditional heat-shrink branch joints.

Applications

  • Urban underground MV ring main unit (RMU) feeder connections
  • Industrial plant loop distribution networks
  • Wind farm collector grid branching
  • Utility lateral tap-off to distribution transformers
  • Commercial building campus MV distribution
  • Network expansion and capacity upgrade projects
