LB6-35 (LB6-110) series oil-immersed vertical current transformer is an upright fully enclosed structure, mainly composed of expander, primary terminal, porcelain sleeve, primary winding, secondary winding, fuel tank, etc. A grounding plate is provided for product grounding, and a drain valve is provided for oil sampling.

LB6-35 (LABN6-35) current transformer principle

LB6-35 (LABN6-35) type current transformer is oil-paper insulated, outdoor type product, suitable for power metering, current measurement and relay protection in power systems with rated frequency of 50Hz or 60Hz and rated voltage of 35kV.

The body of LB6-35 (LABN6-35) current transformer is installed in the fuel tank filled with transformer oil, and vacuum dried and oil-impregnated. The product is fully sealed and can effectively prevent oil aging.
