Sealing Advantages of Cold Shrink Cable Accessories

2023-07-18
The material of cold shrinkable cable accessories is mainly silicone rubber, and the material of heat shrinkable cable accessories is mainly PE, from the point of use, cold shrinkable cable accessories are more convenient, heat shrinkable cable accessories need heating installation, more complex than cold shrinkable cable accessories.

At present, most of the cable heads are installed in the outdoor or directly buried environment, so the sealing performance is particularly important. Among them, the performance and quality of the sealant is particularly important, you can use a highly elastic sealant, its simple operation, reliable performance, maintenance and installation is more convenient.

The cold shrinkable cable attachment is actually an elastic cable attachment, which uses the elasticity of the silicone rubber itself to expand in advance in the factory and put in a plastic support strip, and then install it on site, and remove the support strip to make it shrink naturally.

The "elasticity" of the cold shrinkable cable accessories can avoid the phenomenon of thermal expansion and cold contraction of the cable caused by the atmospheric environment and the load level in the cable operation. In general, its sealing is still very good, the relative price is relatively expensive, you can consider your own factors to choose.

The installation of cold shrinkable cable accessories is to rely on the elastic retraction force at room temperature, rather than using fire heating to shrink like heat shrinkable cable accessories. The early cold shrinkable cable termination is only additional insulation, the use of silicone rubber cold shrinkable parts, the electric field treatment is still in the form of stress cone or stress control tape wrapping.
