ENC - Cold Shrink EPDM Rubber Sleeve

High weather resistance EPDM rubber sleeve expanded and assembled onto a spiral type removable plastic supporting core. Remove the supporting core after sleeve positioned to the cable connector that requires insulation seal protection, EPDM rubber sleeve will quick and tightly shrink onto the joints. Allows to quick construction without using open fire and tools as well as a narrow space.
Applied to seal protection of overhead, buried power cable connection and communication base station cable joints with rated voltage under 1kV.
Operating temperature range:
  • Continuous operating temperature : -55℃~150℃
  • Storage life recommended: 1 Year
