DESIGN Unibody design insulators are one-piece injection molded directly to the rod and sealed to the end fittings with a bead of silicone to give the insulator high dielectric strength and protect it from all environmental conditions. This design is used for standard distribution dead end/suspension insulators. FIBERGLASS ROD A high quality fiberglass reinforced rod is the core of every insulator with ultimate mechanical strength at least twice the maximum working load. END FITTINGS Standard distribution dead/end suspension units are supplied with clevis and tongue fittings meeting ANSI C29 specifications. Ball, socket and eye fittings are also available. All are made of hot dipped galvanized high strength carbon steel and have an ultimate tensile strength rating of 15,000 pounds. All end fittings on dead/end suspension insulators are attached by compression. Every insulator ls proof tested to verify the crimp.

Unibody insulators have end fittings sealed with silicone to eliminate any possibility of moisture or contamination from reaching the fiberglass rod.

INSULATORS SILICONE COMPOSITE INSULATORS We combine the technologies of a fiberglass reinforced rod, metal fittings and our extensive knowledge of elastomeric insulation to produce a high quality composite insulator. Since 1980, thousands of silicone insulators have been installed by utilities worldwide in a variety of environments. Continued outstanding performance is proof of their superior quality and design.
