Medium Voltage Outdoor Current Transformer
This outdoor dry type current transformer is specifically designed for 3.3kV to 13.8kV power systems, ideal for measuring and protection applications. It is commonly utilized in outdoor pole-mounted setups and transmission lines.
Constructed from high-quality ultraviolet-proof epoxy resin, the unit features an amorphous alloy core for metering and premium silicon steel core for protection. Both primary and secondary windings use pure electrolytic copper with professional shielding processing.
