Product overview

Built around the project specification

A line post insulator holds the conductor clear of the structure and carries the mechanical load of the span. Composite construction — a fibreglass core inside a silicone shed system — gives the strength-to-weight and pollution performance that make it the current default for new line construction.

Key features

Fibreglass core with silicone shed system
High strength-to-weight ratio
Retains hydrophobicity under pollution
Range of creepage and mechanical classes

Applications

Transmission and distribution line construction
Substation gantries and structures
Line refurbishment
Compact line designs
