Main Structure
A voltage transformer (PT) consists primarily of five main components: the core, the primary winding,the secondary winding, the insulation system,the casing and accessories. These components work together
to achieve voltage transformation
- Iron Core — Magnetic Flux Path
- Primary winding — parallel voltage
- Secondary Winding — Inductive Output
- Insulation—A Safety Barrier
- Housing & Accessories
PT Core
Imported silicon steel sheet made of PT core, high quality insulation tape, high quality compression sponge, to ensure that resin shrinkage does not affect the performance of PT core, secondary use of high purity enameled wire.
Primary winding of PT
Mechanized winding secondary winding, all wire uses high purity copper enameled wire, each layer uses high quality insulating paper, to ensure that the layer withstand voltage qualified, to ensure the stability of partial discharge test.
