Reliable performance
Lt is made of silicon rubber material and provided with strong tracking resistance, strong corrosion resistance, fine electric performance and long service lifetime, the rubber elastic material is adopted, if sticks on the cable firmly with moist proof function and ibreathel together with the cable, high dielectric constant stress controlling decrases the electric stress of the surface.

Convenient installation
The special cold shrinkable technology is adopted, When installing, neither needing special training, neither needing to push the fire and use special tool, but extract the core wire lightly
