Arresters for transmission, distribution, and substation

Whether it’s transmission, substation, or distribution, our products keep equipment and personnel safe wherever they are used. Discover arresters and insulators that protect power systems in all environments and conditions.

Distribution arresters

Our products are tested and designed to meet or exceed IEEE C62.11 requirements for normal or heavy-duty arresters.

Line surge arresters (LSA)

Protecta*Lite® line surge arresters help avoid faults on transmission and distribution lines. Our arresters prevent insulator flashovers by safely diverting the lightning surge to ground.

Substation class (IEEE) arresters

Safeguard high-voltage substation equipment from lightning damage with substation arresters. Tested to exceed IEEE C62.11 requirements.

Suspension Quadra*Sil® (silicone) arresters

Made from a hydrophobic silicone polymer, the Quadri*Sil® transmission suspension insulator features the latest in polymer insulator design.

Veri*Lite™ insulator (ESP)

Our Veri*Lite suspension insulators (VLS) are designed to directly replace three porcelain distribution bells.

Line Post Quadra*Sil (Silicone)

The highest quality, lab tested, and field proven insulators on the market! Made from hydrophobic silicone polymer and featuring a four-point sealing system.

Line post Hi*Lite (ESP) insulator

With our line post insulators, linemen don’t have to install a crossarm on the pole to support conducting cables. They also prevent electrical current from flowing through the pole itself.
