Can be any shape of the charged body insulation protection without the free end, practicality.
Can be used for larae cable insulation irregular shape conductor insulation protection.
Mines, oil fields, chemical and other electrical systems that can not be used in open flame insulation protectionreactorreactor high and lowtemperature environment.
Main network: Substation and power plant within the following points with a bare part of 35kV can be applied. Applyto the outdoor bus bridge, indoor switch bus, bus hand bus and its screw insulation protection, to eliminate the potentia safety hazard of power equipment, the most effective and convenient way.
Distribution network: equipment electrical connector (screw connection casing, etc.) of the insulation, conductivebrancn line lle bar at the end of eacn type cable cllp cable insulalion proteclon, ring nelwork cabinet busbar cable headcontactinsulation protection.
Silicone rubber fire-retardant insulation self-adhesive tape, also known as cold shrink tape indicators are betterthan the traditional thermal insulation materials, especially for substation integrated insulation protection.
