Three Phase Bushing Current Transformer Epoxy Resin Cast LZZBJ9 10kV

LZZBJ9-10 current transformer is fully enclosed structure, the iron core is made of high quality magnetic conductive material, the primary and secondary windings and the iron core are all poured in epoxy resin, which has excellent insulation performance and moisture resistance, and is easy to clean the surface.
The primary outlet P1 and P2 are respectively on the top of the casting body, and the outlet end of the secondary winding is on the lower part of the casting body. The first group is the metering winding (level 0.2s and 0.2), marked 1S1 and 1S2; the second group is the monitoring winding (level 0.5), marked 2S1 and 2S2; the third group is the protection winding (10P), marked 3S1 and 3S2. At the same time, the secondary winding can be tapped.
If the customer needs, the accurate grade combination can be changed at will. The transformer is reduced polarity. The bottom of the transformer is equipped with a base plate and 4 Φ12 mounting holes.
