Crafting transmission systems for the future

Proven transmission products

Discover insulators, arresters, connectors and other transmission components that support safe, efficient power transmission across the country.

Arresters

Ensure grid stability and longevity. Arresters safely divert lightning surges to the ground, minimizing flashovers and protecting transmission lines.

Connectors

Engineered for exceptional durability and performance, our transmission connectors help prevent line failures and costly repairs.

Insulators

Maintain efficient power transmission over long distances without loss or interruption. Lightweight and safe, silicone insulators keep electrical conductors separate from transmission towers to prevent short circuiting.

Transmission Switches

Designed for high performance, low maintenance, and ease of use, our transmission switches easily isolate faults, reconfigure power flow, and minimize outage impact.

Lineman Tools

Safely install, maintain, or repair overhead transmission power lines. We offer a full suite of tools that help linemen get the job done.

Anchoring and Foundations

We produce guy anchors and helical piles built to withstand the loads of transmission line structures. Our helical piles can be installed without heavy equipment or significant environmental impact.

Enclosures

We offer plastic, concrete, and fiberglass-reinforced polymer enclosures that protect transmission components from corrosion and electromagnetic interference.

Power Apparatus Bushings

Our power apparatus bushings reduce friction for smooth and efficient power transmission.

Accelerating the grid of the future, advancing the grid of tomorrow

Prepare for the future of power transmission. Our testing, engineering, and monitoring support helps you avoid outages, improve product performance, and extend the longevity of your infrastructure.

Power quality monitoring

Enhance grid efficiency with optical sensoring and sectionalizing kits. Precise fault detection and comprehensive power monitoring reduce outage duration.

Expansive product testing

We harness our industry-leading experience, quality, and accuracy to craft high-performing products. Our labs have a wide range of testing capabilities that support grid modernization.

Engineering & customization

TowerPak kits provide all your transmission hardware in one convenient package, so you can spend your time stringing lines instead of sorting, verifying, and staging material at the lay down.
