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 is 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 capacity of heating dispersion

• low loss, energy saving, free from maintenance, small volume, light, and easy for installation

Packed in wooden case
