General
This indoor dry type current transformer is used in 3.3kV, 6kV, 10kV, 11kV, 12.5kV and 13.8kV power system, for measuring and protection.
It has been used in cubicle switchgear or in bay-installed switching stations.
The current transformer is made from high temperature indoor epoxy resin, amorphous alloy core for metering and high quality CRGO core for protection, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
Standards
All UNISUN Electric instrument transformers are in conformity with IEC standards, and recommendations IEC 61869. Transformers in conformity with specific country standards can also be supplied. (IEEE C57.13, NBR6855).

Primary Winding:
A high-electrolytic copper primary winding is used, and a silver-base welding material is used at the welding place. Semiconductor shielded paper is wrapped around it to ensure that the partial discharge testing data is qualified.
Secondary Winding
The large-capacity secondary winding is automatically wound with high-insulation, high-purity enameled wire to ensure a wide capacity output under standard accuracy.
