support insulators - bell type

Support insulators made of polyester material reinforced with red fiberglass.
I2IC type insulators are made by compression molding, and are absolutely unbreakable, with high mechanical and electrical characteristics, can be used even in precarious working conditions (high ambient temperature, in the presence of corrosive substance, etc.).

The material used is certified and classified HL2 according to standard EN 45545-2.
Certified R7, R22 and R23 for railway standard EN 45545-2.
On request, we can supply the insulators with:
– Female inserts in stainless steel or brass
– Female inserts in inches
