Oil Immersed Current Transformer

Current transformer used in transformer is suitable for oil immersed transformer and transformer bushings, etc. Insulating paper wrap around the transformer and even the outgoing line is wrapped up by oil resistant material, thus the compatibility of products with transformer oil is guaranteed.

Reference standard: GB1208-2006  Current Transformer
Voltage class:  110Kv-500Kv
Primary current: 50A-5000A
Secondary current: 1A /5A
Profile dimension: As per customer request

Product features:We use high quality raw materials and optimize calculation, thus the product provides higher precision and higher load while meeting all the constraint conditions.
