The most widely used bushings in the high voltage transmission industry globally even today, Oil Impregnated Paper (OIP) Condenser Bushings are manufactured using Kraft paper wound tightly on a conductor, with a finely graded capacitive arrangement using intermediate layers of aluminium foils, dried under heat and vacuum to remove moisture and carefully impregnated with processed transformer oil.
We engineer various product lines of OIP Condenser bushings with different voltage and current ratings and combinations of insulator options including porcelain or silicone.
All our standard models are type tested at ILAC/NABL Accredited laboratories as per IEC-60137/IEEE C57.19.00/01. For any fresh type test requests, we request you to approach us on individual basis and we can work out a techno-commercial solution suitable for you.

- VCL/VCD/VCS Bushings are High voltage capacitance graded oil-impregnated paper insulated bushings
- The Bushings comply with IEC 60137 standard s performance requirements for application in power transformers
- The main component of Bushing is the Active part and is manufactured using insulating kraft paper wound around a central tube or solid conductor
- During paper winding, aluminium foils are embedded in paper co-axially at pre-calculated locations to optimise the radial and axial electrical field along the bushing
- After winding, the paper core is dried under vacuum at elevated temperatures and subsequently impregnated with high-quality vacuum dried and degassed Insulating mineral oil
- The bushing is assembled in a controlled environment and filled under vacuum with vacuum dried and degassed Insulating Mineral oil
- After oil filling, each Bushing is subjected to an oil-filled over-pressure test for verification of joint sealing
- All bushings are routine tested and type tested in accordance with IEC 60137
