ANC - Cold Shrink Silicone Rubber Sleeve

ANC - Cold Shrink Silicone Rubber Sleeve

High weather resistance Silicone 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, Silicone 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 the sealant protection for cable connectors of communication base station.
