Low Voltage LV Industrial Cable Joints – Prysmian JBR

Low Voltage LV Industrial Cable Joints – Prysmian JBR

Prysmian JBR industrial branch cable joints are used for LV cables with copper & aluminium conductors ranging from 1.5sqmm to 300sqmm and have transparent vacuum formed shells which offer greater working dimensions & interlocking flange seals.

JBR low voltage cable joints include low hazard isocynate free JEM resin which has extremely low viscosity and enhanced adhesion and are designed to allow use with compression or mechanical connectors.

T&D can offer the full range of Prysmian cable joints for low voltage industrial cable jointing applications.

Prysmian JBR Cable Joints

Technical Data

  • Low Voltage Branch Joints for 600/1000 Volt SWA cables to BS5467, BS6346 and IEC 502 – with Polymeric Insulation, aluminium or copper conductors.
  • Tested & Approved to BS EN 50393 & ENA ER C81
  • Constant Force Spring Armour Bonds Included

Prysmian JEM Resin Features & Benefits

  • Easier resin mixing by the cable jointer in “Twin Pack” totally enclosed mixing in a clear laminate sachet.
  • Extremely low mix viscosity allows void free cable joint filling.
  • JEM Resin is insensitive to moisture and will cure under water.
  • Enhanced adhesion to XLPE, MDPE, PVC & lead covered cables.
  • High flash point, non-flammable liquid – no special storage or transport requirements.
  • Not classified as irritating to the skin or eyes.
  • Does not cause skin sensitisation.
