Product Description

product description
LZCK322-10 11kv Split Core Current Transformers ct 400amp

LZCK series 11kv Split Core Current Transformers ct 400amp is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system. It is widely used in compact fully insulated ring network switchgears such as ABB-SafeRing/SafePlus...and cable distribution boxes. The transformer can be directly installed at the inlet and outlet cables.The slice is imported silicon material. The semicircular ring core and secondary windings are vacuum poured by insulated resin.
