A Better Design. A Better Insulator. A Bold Solution.

Hubbell Power Systems is proud to offer a transmission insulator that triumphs over today's unpredictable environment. Appropriately named, Quadri*Sil Insulators incorporate a revolutionary four-point seal, a proprietary silicone-rubber compound, and end seal design. The result – an ultimate shield against contamination and moisture intrusion.
