  LZCT Bushing Type CURRENT TRANSFORMER patent product in China, patent No.ZL200820123909.6,ZL200830132745.9,ZL200830132746.3,the manufacturing process in line with the ISO9001:2008 quality standard requirements of all applicable provisions.
  LZCT Bushing Type Current Transformer is suitable for is suitable for current measurement,metering and microcomputer protection of distribution equipments in 35kV and 10kV AC power system.it is widely used in compact fully insulated ring net switch cabinets and capacitors because of its small volume, light weight,and convenient installment
  The circular ring core and secondary windings are cacuum poured by high quality epoxide resin in the fine retardant plastic casing, which has the characteristic of moisture proof, stable performance and dispensing with maintenance. It can be fixed on the bushings of the ring net switch cabinets and capacitors quickly and uniformly.
  The current transformers can be divided several kinds according to the various current ratio, accuracy and rated loads The specific parameters are showed in the corresponding parameter tables of every type.
