- for indoor use -

Cycloaliphatic epoxy is an organic compound with a ring-like molecular structure and thus the term ’cyclo’. These insulators have proven themselves in all types of electrical operating environments and voltages. All major switchgear manufacturers throughout the world use cycloaliphatic insulators to some degree in their products.

The applications are in metal-enclosed switchgear, outdoor distribution and transmission, pad-mounted switchgear, metal-clad switchgear, surge arresters, transformers and power circuit breakers. The performance of cycloaliphatic epoxies has been outstanding and they have passed the test of time in all kinds of environments.

Cycloaliphatic insulators are about 70% the weight of porcelain insulators, much stronger than porcelain ones and will not shatter due to mechanical/physical shock.
