About Composite Insulators

Composite insulator is a multiple insulation structure composed of continuous layers of different insulation materials, used as a new type of safety insulation material to replace traditional insulators and other electrical insulation devices. It is usually composed of structural layers, intermediate insulation layers, and surface insulation layers. The main structure is usually made of metal, and the insulation material is composed of structural insulation layers and surface insulation layers layer by layer. According to their applications, composite insulators can be subdivided into rod-shaped suspension composite insulators, needle type composite insulators, cross arm composite insulators, pillar composite insulators, etc.

Overall structure: The composite insulator consists of a core rod, umbrella skirt sheath, and connecting fittings. The core rod material is usually fiberglass, providing the mechanical properties of the insulator; The sheath is connected to the surface of the core rod through adhesive to protect the core rod; The connecting fittings are located at both ends of the composite insulator, used to connect the insulator to the tower fittings.

Excellent electrical insulation performance of composite insulators: Composite insulators are composed of different insulation materials and have high insulation strength, which can effectively protect electrical equipment.

Small size and light weight: Compared to traditional insulators, composite insulators have a smaller volume and lighter weight, making them easier to install and maintain.

Excellent anti pollution flashover performance: The surface of the composite insulator is coated with high-value baking paint, which can effectively prevent the influence of external pollutants on its insulation performance.

Composite insulators are widely used in various fields such as high-voltage cables, steel smelting, oil fields, marine engineering, trains, automobiles, power stations, etc. In addition, it is widely used in aviation electronic equipment, such as aircraft engines, airplanes, and aviation equipment, which can effectively prevent damage to electronic devices.
