Product overview

Built around the project specification

Toughened glass discs are assembled into strings sized to the line voltage. Their practical advantage is inspection: a failed glass disc shatters its shell and is visible from the ground or from a helicopter, so defective units are found on a routine patrol rather than by a fault.

Applications

Transmission line suspension strings
