8.7/15kV-630A European style touchable front connector
Application:
The 10kV European type front connector is used in 10kV cable distribution boxes, ring network cabinets, inflatable cabinets and high-voltage switchgear, directly installed on the equipment casing, used for inlet and outlet cable connection and sealing. The product adopts the international advanced post-injection insulation layer process, and the electrical performance has reached the international leading level, which makes it be safer and more reliable to use. The installation is not affected by harsh environmental. The stress treatment of the product adopts international advanced technology. Its structure size is small, which fully meets the requirements of installation space, and it is the leading prefabricated electric head in the world. It is suitable for the cable whose cross-section is 25-630mm2.
