Cold shrink cable terminations minimise the hazard of harming XPLE cable insulation which can be due to overheating or scorching of the cables by the jointer. There is no need of cooling time before the cables are energised.

 Benefits of cold shrink

  • These can be installed fast in one step process without any hassle.
  • It saves labour and makes installation possible in1/3 of the time or can be less as compared to its heat shrink equivalents.
  • When talking of tooling, it does not require any heating tools or work permits needed for hot work.
  • It is compact, and its smooth profile restricts volume displacement that can be caused by cable tray where joints are positioned.
