Sai Guru Engineers

Other Details

We are among the eminent names in the industry for manufacturing and supplying Vacuum Pressure Impregnation Machine. The offered machine is effective in impregnating deep voids of winding for increasing the working ability of wind turbines, generators, transformers, capacitors and coils. This machine is robust in terms of construction as well.

Features:

• Robust construction
• Effective impregnation
• User-friendly

Other details:

Electrical current that rows through a coil always causes a vibration of the entire winding called transformer humming or microphonic effect and generates heat which reduces the life of the windings.

Voids in the windings also accelerates the degradation of insulation material and causes the transformer to fail prematurely.

VPI Plant produces a better insulation for better environmental protection and moisture resistance. The removal of air voids from the windings assures longer electrical life.

These plants are specially used to force an Impregnate / Varnish into the deep voids of winding for better penetration and reduce the air gaps.

These plant are used for insulation treatment of following electrical Product:

• H.V motors and generators
• Wind turbines
• Dry type transformers
• Insulation material of cable
• Power capacitor

Categorization: 

• VPI plant for motor windings
• VPI plant for transformers
