LZCK-55 clamp outdoor waterproof split core current transformer

outdoor IP65 Split core current transformer

The model LZCK-55 split core ct is a 55mm core diameter outdoor split core current transformer. Some clients also called it as outdoor TTCC. Due to its accuracy can be 0.5s and its IP67 protection degree level, this current transformer is widely used together with energy meters for measurement in power utilities. Also this current transformer can be used in outdoor distribution power transformer monitor system.
The semicircular ring core and secondary windings are vacuum poured by insulated resin. Besides infront using field, this model can be used both for measurement and microcomputer protection of electrical equipment in 11KV and 35KV AC power system.
All of our split core current transformers are strictly comply IEC60044-1, IEC 61869-2, NTC 2205, GB1208-2006, GB/T20840.2, ANSI/IEEE C57.13.
