Product Name
LZCK322-10 Germany Cable Type Split Current Transformers |
LZCK series Cable Type Split Current Transformers Germany is suitable for current measurement and microcomputer protection ofelectrical 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.
