- Shatter-proof oil end insulator
- High seismic and SC load withstand capacity
- Available with porcelain or composite insulator housing on air-side
- Excellent thermal performance
- Large size oil indicator for better visibility from distance and angles
- Viton material O-rings for oil sealing
- Special terminals available upon request
- Potential for customization of BCT, oil end length, mounting flange to a large extent
- Exact interchangeability with global reputed makes
- Shortest lead times industry-wide
- 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 oil-filled over-pressure test for verification of joint sealing
- All bushings are routine tested and type tested in accordance with IEC 60137
Our experienced team of design engineers offer a wide range of built to specification Air to Air Wall bushings and Oil to Oil OIP Bushings solutions wherein they work closely with the end-users / equipment designers from the project engineering stage to understand requirements of mounting, ambient environments, wall dimensions, through hole dimensions, cantilever and pollution requirements amongst many other things to arrive at the optimised wall through bushings design adapted for their end-use.
We welcome Inquiries for these highly specialised solutions immaterial of the quantities required whether it is for a few products or volume requirements, also including Retrofit/replacements of existing Wall Bushings or Oil to Oil Bushings of other reputed Global makes.
