1: High voltage Post insulator has high strength, light weight. Can relieve stress, reduce the installation and maintenance of towerof strength, save costs. Because the rod core with tensile strength is high so it can be very handy.
2: High voltage Post insulator aging resistance, good. It has good corrosion resistance, aging resistance, at 70 degrees Celsius is elastic, can be long – term work 20 degrees celsius.
3: High voltage Post insulator has the advantages of small volume, light weight. Because the composite insulator has the advantages of small volume, light weight, and the umbrella disk is flexible, not easy to damage, so it brings great convenience to the transportation, installation, maintenance1: High voltage Post insulator has high strength, light weight.

Composite insulators are available for applications up to system voltages of 110 kV. The core of a composite insulator is a pultruded fiber glass rod which provides a high mechanical strength. In a direct injection molding process a non-tracking, erosion and UV resistant polymeric housing is molded directly onto the fiberglass rod. A corrosion resistant metal end fitting is crimped onto each end of the rod to provide a high mecha nical strength. A new developed crimping control technology monitors the assembly process of the metal fittings and ensures that crimping forces cause no damage to the fiberglass rod while achieving a crimp that will withstand the highest possible mechanical loads. Sealed with a tracking and erosion resistant polyurethane barrier, the core is protected from deterioration due to moisture ingress. Composite insulators are available as tension (suspension), line post and station post insulators. For railway applications, tension and strut composite insulators are available in a large variety of configurations.
