200uH 220uH PQ50 New Energy Magnetics Transformer DW5354

PQ50 New Energy Magnetics Transformer DW5354

High precision current transformer is suitable for current measurement and protection of distribution equipments in 35kv or 10kv AC. power supply system. It is not only widely used in compact fully insulated ring net switch cabinets and load switch cabinet but also cable distribution boxes because of its small size, light weight, open feasibility and convenient. It is very convenient that the transformer can be directly installed at connected output and input cables.
