Features:
High voltage coils are wrapped with Polyester enameled wires, filled with glass fiber, and then resin under vacuum condition. It becomes solid under high temperature. It equipped with high mechanical intensity, low discharge partly; Low voltage coils are wrapped with a whole piece of copper foil, with strong anti-shortcut capacity. The core is made of silicon steel. By reasonable choosing magnetic density, decrease the empty loading loss effectively
Fire protection, anti-explosion, and no pollution
Coil is free from humidity, low noise and well characteristic of heating dispersion
Low loss, energy saving, free from maintenance, small size, light, and easy for installation
