Three Phase Newtek Vacuum Pressure Impregnated Transformer

Backed by our adroit team of professionals, we are able to provide our clients with an assorted gamut of Vacuum Pressure Impregnated Transformer.

VPI type of transformer is made with minimum flammable material as insulation of windings. The windings of this transformer are made in foil or strip in a continuous layer. But for higher voltages, the winding is made of disks that are connected in series or parallel as per power rating with respect to voltage level. The insulation of the winding is void free impregnation that is made with class H polyester resin. The primary and secondary winding with core are laced safely within a vacuum protective box. Moisture Ingress Protection is high and it never gets affected by moisture. This type of transformer is available from up to 250 kVA with insulation grade F(155°C) and H(180°C).

Advantages :

• High mechanical strength
• Void free insulation
• No temperature fluctuation
• Easy maintenance
• Less prone to fire hazard.
