22kV 24kV Cold Shrink Cable Joints For MV HV Cables - Nexans 24CSJ

22kV 24kV Cold Shrink Cable Joints For MV HV Cables – Nexans 24CSJ

Nexans 24CSJ is a cold shrink cable joint suitable for jointing MV HV single core polymeric cable with copper wire screen to be laid in air or directly buried underground – conductor material copper or aluminium with a maximum operating voltage of 24kV. The cold-shrinkable cable joint is fully screened and fully submersible.

All the joint bodies of the Nexans 24CSJ range are tested for AC withstand prior to leaving the factory and meet the requirements of CENELEC HD 629.1.

Nexans 24CSJ - Dimensions

All types of conductor connectors can be used. The conductor connectors must be within the dimensions specified.


 

Nexans 24CSJ Cold Shrink Cable Joint Cable Preparation

  1. Clean the outer sheaths of both cables over approx. 1.5 m
  2. Remove the outer sheaths for a distance of 235 mm from cable ends
  3. Shorten the copper wire screens up to a point 65 mm from the outer sheaths
  4. Wrap the self-adhesive copper tapes around the outer sheaths flush with the ends.
  5. Fold the screen wires back over the copper tapes and secure them with a wrap of adhesive tape to avoid sharp edges. IMPORTANT : the total length of screen connection must not exceed 70 mm.

Cable with bonded or easy strip semi-conductive screen

  1. Remove the extruded semi-conductive screen to a point 45 mm from the outer sheath
  2. Bare the conductors for a distance C + 10 mm (C = 1/2 of the connector length)
  3. THOROUGHLY CLEAN CORE INSULATION. clean

B. Cable with fabric tape screen

Cable with fabric tape screen

Cable with fabric tape screen

  1. Remove the fabric tape to a point 45 mm from outer sheath
  2. CAREFULLY REMOVE THE GRAPHITE COATING WITH AN APPROPRIATE SOLVENT
  3. 3.Apply one layer of semi-conductive tape to a point 45 mm from the outer sheath
  4. 4.Bare the conductors for a distance C + 10 mm (C = 1/2 of the connector length)
Cable with fabric tape screen

Cable with fabric tape screen

  1. As a protection, wrap a few turns of adhesive tape around the conductor ends
  2. 2.Slide the joint housing over one cable end. Make sure the end with cable tie goes first over the cable
