Medium voltage Outdoor Current Transformer
This outdoor dry type current transformer is used in 33kV, 35kV, 36kV and 40.5kV power system, for measuring and protection. It has been used in outdoor pole mounted and transmission line. The current transformer is made from high quality ultraviolet-proof epoxy resin, amorphous alloy core for metering and high quality silicon steel core for protection, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
Standard: IEC standards IEC 61869, IEEE C57.13
