String & Insulator Hardware

Every line begins where the conductor meets the tower.
Insulator strings hold the conductor to the tower and hold it clear — forged, tested, and assembled in-house from 33kV to 1200kV.

Conductor Accessories

A bundle only performs if it holds its shape.
Spacers, connectors, and dampers keep bundled sub-conductors in formation — the difference between decades of service and premature failure.

Spacer Dampers

One design, proven across the coldest and hottest grids on earth.
TAG's flagship — holds the bundle apart and damps vibration. Over 3 million supplied, proven from −30°C to +50°C.

OPGW Hardware & Accessories

Hardware for the fiber-optic ground wire — grips firmly enough to hold decades, gently enough to protect the fiber inside.

Power does not end at the grid.
