It is mainly composed of hollow composite insulator, capacitor core, metal accessories, insulating pipe in oil, transformer oil, etc. Compared with traditional porcelain insulated transformer bushing, SHEMAR product inherits the performance advantages of hollow composite insulator. At the same time, combined with the mature overall seal structure design and the international leading capacitor core manufacturing process, to ensure that the overall electrical, mechanical and sealing performance of the product is more reliable.
Prevent explosion, brittle break, flashover and aging:The main body of external insulation adopts SHEMAR technology substation composite hollow insulator, which eliminates explosion, brittle fracture, flashover, aging and other problems.
No leakage:SHEMAR oil impregnated paper capacitive bushing adopts mature gluing technology and integral sealing solution of substation composite insulator, which makes the bushing form an integral structure and ensures long-term reliable operation without leakage.
Reliable internal insulation:The capacitor core adopts wide cable paper winding process, combined with the end screen structure design, to improve the allowable field strength; The whole electric field is calculated by simulation to ensure that the design field strength is less than the allowable field strength.
Low cost:The cost of procurement is far lower than that of dry casing, and the whole life cycle is free of operation and maintenance, so the economic advantage is more obvious.
