LZCG2500-10 MEDIUM VOLTAGE 100/5A PROTECTION ZCT ZERO SEQUENCE CURRENT TRANSFORMER 5P20
INTRODUCE
The Model LZCG2500-10 ZCT is a ring type resin casting zero sequence current transformer. Some clients also called it as zero phase current transformer & TTCC. This current transformer can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power system 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 good linear and more than 20 years using life in order to be qualified with all the jobs. The ring core and secondary windings are vacuum poured by high quality epoxide insulated resin ,which has the characteristic of moisture proof, stable performance and dispensing with maintenance. Current transformer protection class 5P20, 5P10, 10P20, 10P10, 10P5.
All of our GFUVE zero sequence current transformers are strictly comply IEC60044-1, IEC 61869-2, ANSI/IEEE C57.13, GB1208-2006, GB/T 20840.1-2010, GB/T20840.2-2014, GB/T 22071.1-2018, IEC/EN61010-2-032, IEC/EN 61010-2-031.
