15KV line post insulator,composite line post insulator
15KV line post insulator has light weight, up to 80% less than Ceramic line post insulator. Composite line post insulator is used on transmission and distribution lines.
15KV line post insulator is suitable for pollution level falls under IEC 60815 Classification-E7 (very heavy). To improve the performance & life of composite line post insulator, the electric field on the live end of insulators must not exceed 4.5kV/cm (corona onset for water drops - reference EPRI, USA).
Composite line post insulator consists of fiberglass rod core, housing, sheds, metal end fittings and silicone rubber. The core made up of fiber glass rod is the insulating part of the insulator. The end fitting connection adopts the zinc cover protection. The middle of the 15KV line post insulator sheds is made from high quality silicone rubber composition.
To ensure the quality about the 15KV line post insulator, we do tests for them. We have high quality and competitive price for composite line post insulator. Many customers are satisfied with our considerate service. We represent some of the Chinese leading manufacturers of composite high voltage insulator.
