Composite long rod insulator,Silicone Rubber Long Rod insulator

Composite long rod insulator is one type of the composite insulator: another said is silicone rubber long rod insulator.
Composite long rod insulator introduction:
Overhead power transmission and distribution lines require both cables from the steel towers by which they are supported. The insulators have conventionally been made of ceramics or glass. These materials have outstanding insulating properties and weather resistance, but have disadvantages of being heavy, easily fractured, and subject to degradation of their withstand voltage properties when polluted. There was therefore a desire to develop insulators of a new structure using new materials that would overcome these drawbacks. Composite insulators gradually replace them; more and more countries used Composite insulators.

Composite long rod insulator mechanical reliability
The quality of the rod is adjective use for the long term mechanical reliability of composite suspension insulator. Mechanical reliability is one of the important Composite long rod insulator parameters, except, high voltage, materials are also important.
Features of Silicone Rubber Long Rod Insulator
1. High quality HTV silicone rubber for the sheds of composite insulator
2. Epoxy Pultrusion FRP core of the composite insulator
3. Hot Dip Galvanized Forged or Cast Steel for metal end fittings of the composite insulator.
4. Whole molding and injection technology.
5. Metal End Fittings are directly crimped to the composite insulator core rod by a circumferential crimping process.
6. Superior bending and torsion strength as well as anti-explosive, un-puncture performances.
7. Application in heavy polluted and hard-to-reach areas (swampy areas &highlands).
