10-330KV LB SERIES DEAD-TANK OIL IMMERSED CT

New Products / New Technology

The current transformer is outdoor, single phase and oil immersed dead-tank type, which is used for metering and relay protection of 10~330kV,50 or 60Hz system. The product is adopted to high dielectric strength oil-filled designs using oil paper insulation, the primary insulation is wound from high voltage cable paper. This ensures conservative reliable performance for decades of service in demanding global outdoor environments.

33-220KV LVB1 SERIES LIVE-TANK OIL IMMERSED CT

New Products / New Technology

Oil immersed live tank current transformer, this series are inverted fully sealed structure, consist of primary winding, body, bellows, upper and lower oil tanks, porcelain bushing, base and terminal box, etc. The body adopts oil-paper capacitive divider insulation, with high insulation utilization and uniform electric field distribution. Secondary winding is placed in the aluminum alloy shield, preventing high voltage attack during high energy discharge and protecting secondary instruments and relays. Oil tanks are made of aluminum alloy with high strength, good sealing and stainless. The stainless steel expander at the top of the product can adjust the volume of oil based on changes of temperature.
