|---|---|
| Brand Name : | GFUVE |
| Type : | Electromagnetic |
Product description
Window Type Split Core Current Transformer LZCK350-10 is made by professional current transformer manufacturer GFUVE.
LZCK series split core current transformer 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.
