Main Structure

A current transformer (CT) primarily consists of five major components: the iron core, the primary winding, the secondary winding, the insulation system, the housing, and the terminals. These components work together to achieve current transformation and electrical isolation.

Primary winding

High electrolytic copper is used as primary winding, silver base welding material is used at the welding place, and semiconductor shielded paper is wrapped to ensure that the partial discharge tseting data is qualified.

Secondary winding

Large capacity design secondary winding, automatic winding, high insulation and high purity enameled wire, to ensure wide capacity output under standard accuracy.
