LZCG930-10 Cheap low voltage Cast Resin Ring Core Current Transformer

low voltage Ring Core Current Transformer

The Model LZCG930-10 CT is a ring type resin casting current transformer. Some clients also called it as TTCC. This current transformer can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power system, It is widely used in not only compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus, Unstitch, Schneider RM6, SM6, Siemens 8DJ10/8DH10, Simosec, FBX, Fluokit, Omar Garbo GA, GAE; SEL TPS(Q); VEI Unifluorc; Eaton SVS/12 ring network, but also cable distribution boxes because of its small size, light weight, operable and convenient installation. It is very convenient that the transformer can be directly installed at the inlet and outlet cables.

 

New magnetic material is taken to be the core of the current transformer, which has high magnetic permeability, low saturation magnetization and good stability. Therefore, the measuring accuracy is higher and the instrument security factor is lower. Since the high quality silicon processed by advanced technology is taken to be the core of the protection windings, which assured the accuracy limit factor is higher.
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 ring core and secondary windings are vacuum poured by high quality polyurethane insulated resin ,which has the characteristic of moisture proof, stable performance and dispensing with maintenance.
All of our ring core current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, GB20840.2-2013, ANSI/IEEE C57.13.
