Summary
The current transformer of type LCWD-36 is oil insulated and outdoor product. It is used for metering energy, current and relay protection in electric system up to rated frequency 50Hz or 60Hz and rated voltage 36kV.
Model
Structure feature
The type of product has compact structure, small volume, lightweight and its body treated by drying vacuum. It is installed in the bushing filled with transformer oil. The bushing's upper half-part is the primary winding and its dowen half part is the secondary winding. The primary winding's end is led from the two side of the cabinet's w all.
