CERAMIC HOLLOW INSULATORS

Hollow insulators are used in several kind of applications, such as bushings for power transformers, instrument measuring transformers, wall bushings, circuit breakers, surge arresters and cable terminals to mention some areas of useage. The design of the hollow insulators depends on customer requirements, and installation in the final equipment. The hollow insulators are supplied with or without flanges, made of different materials.

CERAMIC HOLLOW INSULATORS
Other types in this category are indoor bushing or outdoor-indoor bushings used for passing through walls. These insulators are assembled with a mid-flange and a conductor passing through the insulator.
