Medium Voltage Outdoor Current Transformer
This outdoor dry type current transformer is designed for 33kV to 40.5kV power systems, specifically for measuring and protection. It is widely used in outdoor pole-mounted installations and transmission lines. Constructed from high-quality ultraviolet-proof epoxy resin, it features an amorphous alloy core for metering and high-quality silicon steel core for protection. Both primary and secondary windings use pure electrolytic copper with professional shielding processing.
