10kV European type rear arrester
Application:
The 10kV rear arrester is installed behind the front and rear joints of the ring network cabinets, inflatable cabinets, distribution boxes and high-voltage switchgear. It can provide reliable overvoltage protection for electrical systems. The outer semi-conductive layer of the shielded arrester ensures the personal safety of the installation and maintenance personnel and the safe operation of the equipment, and the unique properties of waterproofing and moisture-proof ensure the safe and reliable operation of the product in the harsh environment.
