General<\/strong>
This indoor dry type current transformer is used in 15kV, 17.5kV, 20kV, 22kV and 24kV\u00a0power 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.<\/p>

Standards<\/strong>
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).<\/p>
