Wholesale Composite Insulator, Composite Insulator Manufacturer

In electrical power systems, composite insulators are of utmost importance. They are not only essential for supporting and insulating electrical conductors in power grids, but also find extensive applications in various other fields such as electrified railways and oil & gas drilling operations. By preventing current leakage, they ensure the safe and stable operation of electrical systems under diverse conditions.

Composite insulators function by providing a high level of electrical insulation between conductors and supporting structures. They are engineered to possess excellent mechanical strength, enabling them to bear the weight of conductors and withstand mechanical loads like wind and ice. The housing, typically made of silicone rubber, is weather-resistant and hydrophobic. This property helps prevent the formation of water films on the surface, thus reducing the risk of flashovers.

Composite Insulator Components

● Core Rod:

Usually crafted from high-strength fiberglass reinforced plastic (FRP), the core rod offers crucial mechanical support for the insulator. Its high tensile strength allows it to endure substantial mechanical forces.

● Housing:

Composed of silicone rubber, the housing not only protects the core rod from environmental damage but also provides reliable electrical insulation.

● End Fittings:

Attached to both ends of the core rod, these fittings are mainly made of forged iron or aluminum. They play a vital role in securely connecting the composite insulator to power line structures, conductors in power grids, as well as relevant components in electrified railways and oil & gas drilling equipment, ensuring a stable and dependable connection.
