Composite Insulators

The one-piece silicone formulation weathershed material is injection moulded directly to a high-quality, corrosion-resistant fiberglass reinforced 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.


Standard distribution dead/end suspension units are supplied with clevis and tongue fittings meeting ANSI C29-2 specifications. Ball, socket, and eye fittings are also available. All are made of hot-dipped galvanized high-strength carbon steel (stainless steel available upon request) with an ultimate tensile strength rating of 15,000 pounds (6,800 kg). All end fittings on dead-end/suspension insulators are attached by compression. Every insulator is proof tested to verify the crimp.


The various phase-to-phase ratings available include 15kV, 28kV, 35kV and 46kV (dead-end/suspension) or 27kV (dead-end only).
