The Model LZCK2500-10 zero phase ct is a ring type resin casting split core current transformer. Some clients also called it as TTCC. This model can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power system of ring network switchgears such as ABB-Safe Ring/Safe Plus...and cable distribution boxes.
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 current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, GB20840.2-2013, ANSI/IEEE C57.13.
