What are the national standards for 25kv high-voltage power distribution room insulation mats?
High-voltage power distribution room insulation mats can be custom-made in different sizes, colors, and with different text for safe construction insulation mats according to customer requirements. Insulation mat rubber sheets have large volume resistivity and resistance to electric breakdown. They are made of non-polar rubbers with excellent insulation properties such as NR, SBR, and IIR. Insulation mats are used as insulating materials on work surfaces or floors in places like power distribution. National standard: This product is mainly applicable to substations, power plants, power distribution rooms, etc.
Specifications of high-voltage power distribution room insulation mats :
(1) According to voltage levels, they can be divided into 5kv, 10kv, 15kv, 20kv, 25kv, 30kv, 35kv;
