Single-core cold-joint sub-brand

Popular single-core cold-shrink joint sub-brands include TE Raychem CSJA, 3M QSIII, Nexans EASY TECH, Raytech Monoblock, and REPL RCSJ-X.TE Connectivity – Raychem CSJATE Connectivity offers the Raychem CSJA Cold Shrinkable Single Core Straight Joints, designed for fast, reliable installation without void fillers. These joints feature a pre-expanded silicone rubber body with integrated stress cones and a Faraday cage for excellent electrical stress control. They are suitable for a wide range of cable types and meet international standards including IEC, BS, and VDE. The joints provide high dielectric strength, tear resistance, and low-temperature recovery, making them ideal for medium- to high-voltage networks .3M – QSIIIThe 3M Cold Shrink QSIII 33kV single-core joints are polymeric cable joints suitable for XLPE and EPR insulated cables with copper tape or wire screens. They allow safe, flame-free installation and cover multiple configurations including straight inline, transition, trifurcating, branch, and pot-end joints. The QSIII line is widely adopted by utilities and tested to standards such as VDE0278, HD629, and BS7888, supporting voltage classes from 6.6kV to 66kV .Nexans – EASY TECHNexans EASY TECH cold-shrink joints use a double-layer EPDM body for high mechanical and chemical resistance. They are designed for low- and medium-voltage applications and provide constant pressure on the cable throughout the joint's lifetime. The system simplifies installation with shear bolt connectors and requires minimal tools, making it suitable for onshore and offshore networks, including renewable energy projects .Raytech – Monoblock JointsRaytech Monoblock single-core joints are compact kits for extruded cables up to 12/20 kV (Um 24 kV). Each kit contains a pre-dilated joint on a spiral support, allowing fast, safe installation without tools or heating. They are suitable for outdoor, underground, and underwater applications, providing a complete solution for medium-voltage networks .REPL – RCSJ-XThe REPL RCSJ-X range includes medium-voltage straight joints for single-core and three-core cables up to 36kV. The kits feature cold-shrinkable molded joint bodies, earth/armour continuity materials, mastic sealing tapes, and outer protection options. They are fully tested to CENELEC HD629.1 standards and are available for both armoured (RCSJA) and unarmoured (RCSJU) cable types . These sub-brands represent the leading options for single-core cold-shrink joints, offering reliable electrical performance, ease of installation, and compliance with international standards. Selection depends on voltage rating, cable type, and installation environment.
