LZCT-10/24 Bushing Type Current Transformer

General description:

LZCT Bushing Type Current Transformer is suitable for current measurement, metering and microcomputer protection of distribution equipments in 35kV and 10kV AC power system. It iswidely used in compact fully insulated ring main unit and Reactive compensation device because of its small volume, light weight, andconvenient installment.

The circular ring core and secondary windings are vacuum pouredby high quality epoxide resin in the fire retardant plastic casing,which has the characteristic of moisture proof, stable performanceand dispensing with maintenance. It can be fixed on the bushingsof the ring main unit and Reactive compensation device quickly anduniformly.

The current transformers can be divided several kinds accordingto the various current ratio, accuracy and rated loads. The specificparameters are showed in the corresponding parameter tables ofevery type.
