This outdoor dry type current transformer is used in 33kV, 35kV, 36kV and 40.5kV power system for measuring and protection. It is widely applied in outdoor pole-mounted systems and transmission lines. Crafted from high-quality ultraviolet-proof epoxy resin, it features an amorphous alloy core for metering and high-quality silicon steel core for protection. Primary and secondary components utilize pure electrolytic copper with shielding processing for both winding and core.
