Product overview

Built around the project specification

Suspension insulators hang the conductor from the tower and take the full tension of the line at anchor points. The long-rod composite form replaces a string of discs with a single unit, which removes the puncture failure mode of cap-and-pin strings and cuts the weight a tower has to carry.

Key features

Single-unit long-rod construction
No puncture failure mode
Light compared with an equivalent disc string
Specified by mechanical and electrical class

Applications

Overhead transmission line suspension sets
Tension and anchor sets
River and road crossings
Line uprating projects
