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

Product Overview

The WNRLN CSJ-24/3C-120-SI is a premium 24kV silicone cold shrink straight cable joint kit designed for 3-core XLPE insulated power cables with conductor sizes 70mm² to 120mm². Utilizing high-temperature vulcanized (HTV) silicone rubber insulation, this joint kit delivers exceptional thermal stability up to +180°C, making it the ideal choice for demanding industrial environments, high-ambient substations, and regions with extreme temperature swings.

Key Features

  • HTV Silicone Rubber Insulation – Superior thermal resistance from -60°C to +180°C continuous operation, far exceeding EPDM limits. Excellent UV, ozone, and corona discharge resistance for outdoor and high-altitude installations.
  • 24kV Rated Voltage – Designed and tested for 24kV (Um=25kV) medium voltage power distribution per IEC 60502-4.
  • Cold Shrink Installation – Pre-stretched silicone body on removable spiral core. Pull out the core for instant, uniform contraction – no heat, no gas, no tools.
  • 3-Core Straight Joint Design – Integrated three-phase connector with stress control, insulation, shielding, and outer sealing in one compact assembly.
  • Wide Conductor Range – Compatible with 70-120mm² sector-shaped or round stranded copper/aluminum conductors.
  • Hydrophobic Surface – Silicone rubber naturally repels water and resists tracking, providing superior pollution performance in coastal and high-humidity environments.
  • IP68 Sealed – Triple-layer moisture barrier ensures reliable operation in direct burial and submerged applications.
  • Fast Installation – Typical joint completion under 50 minutes by a trained two-person crew.

Applications

  • High-temperature industrial plants (steel mills, foundries, glass factories)
  • Coastal and offshore wind farm collector grids
  • High-altitude substation cable interconnections
  • Underground MV distribution in tropical climates
  • Mining and chemical processing power systems
  • Cable repair in fire-resistant circuits
