34.5 kv High voltage Pin insulators 8190R-70

Product Information

Specification

About

Pin type insulators are designed to provide line support. The function of these insulators is to support the conducting cable directly on the head or neck of the insulator (top and side grooves).

Pin type insulators are designed and manufactured according to ANSI standard (C29.6) to ensure their electrical and mechanical performance, as well as to satisfy all dimensional specifications and requirements. We offer low and medium voltage pins, and are used in distribution lines ranging from 7.2kV to 34 Kv.

These insulators are also offered with a semi-conductive glaze, generally used to homogenize the field generated by the electrical path through the conductor that may cause radio interference.

Pin type insulators are mounted on metallic cross arms, wood cross arms or directly on the post.
