cold shrink cable joints

Cold shrink cable joints are liquid silicone rubber injection molding in the factory vulcanization molding, and then expanded, lined with plastic spiral support components of various cable accessories, on-site installation, these pre-expansion pieces in the processing of the cable End or joint, out of the internal support of the plastic support bar, press the cable insulation on the composition of the cable accessories. Because cold shrink cable joints are at room temperature by elastic retraction force, so commonly known as cold shrink cable accessories.

·Long-term use temperature range:-55℃~ 105℃;
·The aging life:up to 20 years;
·Radial quartile shrinkage rate ≥ 50%;
·Longitudinal shrinkage rate:<5%;
·Contraction temperature:110℃~140℃;
·Scope: Cold shrink cable joints are very suitable for high altitude and cold areas, wet areas, salt spray areas and in heavily contaminated areas. Without fire, and the installation is especially suitable for the petroleum, chemical, mining, tunneling and other flammable places.
