Specifications

Suitable for 10 ~ 35kV single or multi-core XLPE insulated power cable from the connection, the role of sealing and insulation.

 

Product role 
    Suitable for 10 ~ 35kV single or multi-core XLPE insulated power cable from the connection, the role of sealing and insulation.

Features 
    1, reliable insulation: imported high elastic silicone rubber preform, always maintain the right radial pressure on the cable body accessories are installed, linked closely together, not for cable runs respiration and interface breakdown within the interface. Stress control part of the main insulation composite as a whole, to effectively solve the problem of electric cable outer shield the fracture stress concentration, to ensure that the insulation, the safe operation; 
    2, environmental adaptability: the product has a very strong anti-tracking and radiation resistance, excellent weather resistance, corrosion resistance, anti-foul, anti-aging advantages, suitable for high altitudes, cold areas, wet areas, salt fog areas heavily contaminated areas; 
    3, the selection of fit: the cold shrink structure, each specification is applicable to a variety of cable diameter; Easy to install: all products are factory preforms, install and operate, no special training, saving time and effort. The shrink Installation solve cable accessories contraction is not tight or loaded into the phenomenon, reducing the the quality accidents caused due to improper operation. Install without hot work, especially for the petroleum, chemical, mining, tunneling and other flammable places.
