Cold shrink joint body is made of liquid silicone rubber with hydrophobic performance and is erosion resistant. High elasticity and ability to shrink ensure powerful and constant active pressure between rubber and cable that can respond to expanding or shrinking cable diameters under load cycle.
This product has excellent insulating performance and high elastic, resistance and corrosion resistance of the electric mark etc, at the same time, excellent electrical performance; Long service life, after installation to always maintain the appropriate cable ontology radial stress. Make the interface bond within close, at the same time and cable keep share, won't because of the operation of breathing cable and electrical break-down; Stress cone and the composite insulation for an organic whole. Effective to solve the cable semi-conducting layer in the fracture of the stress concentration problems, ensure insulation, reliable, and safety of operation.
