20kV cold shrink cable accessories

20kV cold shrink cable accessories series products, suitable for 12/20, 18/24kV single core, three core

polyethylene and cross-linked polyethylene power cables. Cold-shrink cable accessories are made of

imported liquid silicone rubber material, which not only has very good electrical performance, but also

has excellent hydrophobicity, high elasticity, long service life and constant shrinkage pressure and other

physical characteristics. Using cold shrink cable accessories, without open fire and special tools, only

gently extract the plastic support strip can be automatically shrink and reset, installation is very convenient

to work. With good electrical and mechanical properties, it can be used in various harsh environmental

conditions for a long time. It has the advantages of light weight and easy installation. It is widely used in

electric power, petroleum, chemical industry, metallurgy, railway, port and construction
