Webster-Wilkinson Resin Bushings
resin bushings
Webster-Wilkinson offer a complete range of bushings which are robustly built using resin insulation and designed for use on power transformers operating at LV MV HV electrical voltages.
One of the main benefits of using resin bushings instead of porcelain bushings is the design. The conductor is embedded into the resin and sealed against oil ingress. Therefore there are fewer opportunities for operational failures through gasket issues.

Switchgear & Transformer Bushings
Contact us for complete range of Indoor & Outdoor Transformer Bushings manufactured in accordance with IEC 60137 and product standards including EN50386 and EN50180. A standard range of porcelain bushings are offered according to EN50336 (historically BS2562 & BS6435) for use up to 36kV 4000A.
Cable box bushings are designed for use indoors but can be used in several insulating mediums typically oil/compound (fully insulated), oil /air (partially insulated) and air/air (partially insulated).
- BS EN 50386 Bushings up to 1kV and from 250A to 5kA for liquid filled transformers
- BS EN50180 Bushings above 1kV up to 52kV and from 250A to 3,15 kA for liquid filled transformers
- BS EN50336Â Bushings for transformers and reactor cable boxes not exceeding 33kV/36kV
