Background.
 
Proven in use since the fifties in the extremes of the North American climate, Epoxy-Silica solid insulant dry transformers overcome location and fire hazard limitations of liquid and open ventilated designs.

Their non flammable construction, attractive compact appearance and quiet operation allow them to be located unobtrusively in schools, hospitals and laboratories.


 
The sealed construction makes them suitable for indoor or outdoor use in the hostile environments of manufacturing industries, steelworks, quarries, mines, ships and chemical plants.

Since commencing manufacture in 1971, JENSTAR has supplied over 100,000 encapsulated transformers in ratings up to 100 kVA.

They can be found on top of high temperature furnaces, beneath mobile broadcasting vehicles, North Sea oil platforms and in Japan, Russia and America.
