Composite Suspension Insulator
Composite Suspension Insulators are electrical components designed specifically for suspension applications in high-voltage electrical systems. They consist of a core material made of insulating silicone rubber or other polymer materials, surrounded by a weather-resistant, flexible outer shell. The suspension insulators are suspended from overhead power lines and provide electrical insulation between the conductor and the support structure.
These insulators have several advantages over traditional porcelain or glass insulators, including being lightweight, easy to install, and having a higher mechanical strength. They are also resistant to moisture, UV radiation, and pollution, which can cause insulators to degrade over time. This helps to extend the service life of composite suspension insulators and reduces maintenance costs.
Composite line post insulators
Composite line post insulators are electrical components used to support overhead electrical conductors in power distribution and transmission systems. They consist of a core material made of insulating silicone rubber or other polymer materials, surrounded by a weather-resistant, flexible outer shell. They offer several advantages over traditional porcelain or glass insulators, including higher mechanical strength, lighter weight, and resistance to environmental factors such as moisture, UV radiation, and pollution.
Composite pin-type insulators
Composite pin-type insulators are electrical insulators used in high-voltage power systems. They consist of a fiber-reinforced composite material molded into a cylindrical shape, with a metal pin embedded for attachment. They offer advantages over traditional ceramic or glass insulators, including higher strength, better resistance to weathering and contamination, and lighter weight. They are used in power transmission, distribution systems, substations, and electrical equipment.
Composite Cross-arm Insulator
Composite cross-arm insulators are a subcategory of cross-arm insulators made from fiber-reinforced composite materials. They offer several advantages over traditional porcelain or glass cross-arm insulators, including:
Lightweight: Composite cross-arm insulators are much lighter than porcelain or glass insulators, making them easier to handle and install.
Improved weather resistance: The composite material used in these insulators is highly resistant to weathering, making them well-suited for use in harsh outdoor environments.
Increased mechanical strength: The fiber-reinforced composite material used in these insulators provides improved mechanical strength, making them suitable for use in applications where high mechanical loads are encountered.
Enhanced electrical performance: Composite cross-arm insulators have a low dielectric constant and loss tangent, which helps to improve their electrical performance and minimize energy loss.
Composite cross-arm insulators are commonly used in high-voltage power transmission and distribution systems, particularly in outdoor applications where weather resistance and high mechanical strength are important considerations.

Composite Anti-Wind Insulator
The application of composite anti-wind insulators can be seen in electrical power transmission and distribution systems where they are used to prevent power outages caused by wind-induced movement of electrical conductors. They are particularly useful in areas with high wind speeds, where traditional insulators may not be effective. The composite material provides excellent mechanical strength, making it resistant to damage from wind and other environmental factors, and helps ensure the reliability and stability of the electrical system. These insulators are also used in various other industrial and commercial applications where electrical insulation is required, such as in electrical substations, switchyards, and electrical power plants.
