Low voltage indoor Current Transformer
This indoor dry type current transformer is used in 0.66kV, 0.75kV power systems for measuring and protection. It is widely applied in cubicle switchgear or bay-installed switching stations. Constructed with high-temperature indoor epoxy resin and an amorphous alloy core for metering, it ensures high-quality protection with pure electrolytic copper.
