DIN Bushing Range

Originally designed in Germany, this range of bushings was quickly adopted in Europe – as well as the Far East and Middle East Regions of the world. The design is typified by its use of a doughnut shaped oil seal compressed around a terminal ‘bolt’. The porcelain is shaped internally to retain the bolt and also to prevent it from rotating. The Standard range is limited if you require multiple cable take-offs, but Webster-Wilkinson Ltd can produce solutions to this and many more termination problems besides.

Compliance Standards
DIN 42530, DIN 42531, DIN 42532, DIN 42533, DIN 42534, DIN 42539, DIN 42541
BS EN ISO 60137

Available Designs
We can offer all designs contained in the relevant DIN Standards. Additionally, we are able to offer, in some instances, high creepage versions. Arcing horns can be provided for bushings of 12kV and above- if required.

Insulators
Ceramic insulators are porcelain brown-glazed.

Metalwork
All bushings normally utilise unplated (self-colour) conductors and terminals. Conductors can be tin-plated by special order.

Termination
Standard air-side terminations are normally screwed, round conductors. We can supply palm or flag terminals – if required. Oil-side termination is either via draw lead or via screwed, round conductor or flat threaded lugs.

Fixing
Up to 12kV, bushings are normally supplied in kit form and are of two-piece porcelain design. 12kV bushings and above are fixed via a formed light gauge clamp and fixing pieces which locate on the transformer facing – studded by others. Fixings and fasters are available in a range of materials and finishes.
