The installation of 1kV Cold Shrinkable Single Core Straight Through Joint is cold shrinkage construction, in the process of construction as long as the plastic wire core of the cable can automatically complete the contraction, without heating, this process is simple and practical, relative to the installation of heat shrinkage cable to eliminate the phenomenon of uneven shrinkage of insulation tube. When the heat shrinkable cable accessories are installed, the cable needs to be heated, which is easy to lead to uneven heating or no contraction at all, thus affecting the construction quality.
