We are manufacturing condenser bushing from 52 kV to 220 kV voltage class, in compliance with IEC 60137 and IS 2099.

Each Bushing Transformer unit is strictly routine tested  in an isolated shield HV AC Series Resonant System with specially made cage room for Partial Discharge and Capacitance & Tanδ to assure its quality and technical specifications.

Condenser Bushing Construction

Condenser Bushing Core Winding – A fully automated winding machine winds a High Quality Insulation Paper on Aluminum Tubes and a closed loop control. At predefined locations by the winding program, precisely cut Aluminum Foils are inserted to achieve the uniform condenser grading.


The Cores are then assembled with the assembly components such as Air End Porcelain Insulator, Oil End Epoxy Insulator etc. The Entire Assembly is a Tie Rod Assembly with the “O” Rings used at all sealing locations. The Assembly is perfect sealing at highest operating temperatures and also supports the assembly against the Loads applied at HV Terminal.  Self Earthing type Test Tap / Capacitance & Tan Delta Measurement Tap & Oil Filling, Sampling Valves are provided at Mounting Flange Level.

Drying & Impregnation

The completely assembled unit is kept under Vacuum for 36-60 hrs. After the drying cycle is concluded, oil filling is carried out at a predetermined rate of oil flow which is in relation with the Capillary Rise of the Paper Insulation.

Sustainability goals

We offer the most complete industrial solutions in the century for the research, design & development of materials.
