1)Outline
This series current transformer applies in the circuit with the rated frequency of 50, 60Hz, rated voltage of 10 kV and below indoor installations for current, power measurement and protection purposes.
This product is a wholly closed maintenance-free product made from epoxy.
2)Brief of Structure
A coil and the secondary coil of current transformer have the chain-shaped structure. Measurement-level core is made from nanocrystalline alloy. Protect-level core is made from quality-rolled silicon steel plates, secondary wire winding on the core uniformly. A coil is made from quality soft copperbelt enameled wire or glass fiber derived rolling.
