LZCK322-10 11KV 33KV High voltage Split Core CT current transformer

High voltage Split Core CT current transformer

The Model LZCK322-10 is a ring type resin casting split core current transformer. Some clients also called it as TTCC. This model split core ct can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power system. It is widely used in compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes. The split core current transformer can be directly installed at the inlet and outlet cables.The slice is imported silicon material.

We used imported silicon material and using our mature advanced producing technology we make sure our transformer has very goog linear and more than 20 years using life in order to be qualified with all the jobs. The semicircular ring core and secondary windings are vacuum poured by insulated resin. All of our split core current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, GB20840.1 & 2, ANSI/IEEE C57.13.
