PI/P polyglass bushings

Bushing insulators in polyester polyglass material reinforced with fiberglass in red color.
PI/P type bushing insulators are manufactured 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 pass-through insulators are made up of 2 polyglass insulating pieces that fit one inside the other. The blocking is done by a rod and 2 nuts, one of which is fixed to the rod. The conductors are locked with the rod and the nuts. The conductors can be connected or disconnected on both sides without twisting or unscrewing them.
The central rod of the socket is made of nickel-plated brass.
Nuts and washers in nickel-plated brass and galvanized steel

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.
