Composite insulators are often used in electrical equipment to support and separate electrical conductors, and do not allow current to pass through the insulator.
The structural design of the composite insulators we produce varies, but they are mainly composed of core rods, sheds, and hardware (Base Connector & Oval Eye).
The core rods of composite insulators generally use epoxy glass pull rods (glass fiber reinforced plastic rods are also commonly used), which are mainly used to bear mechanical loads and serve as the internal insulation of composite insulators. And it meets the standard requirements of “color penetration test” and “water diffusion test”, and has good fatigue resistance, crack resistance and creep resistance.
We use high-quality high-voltage insulating silicone rubber polymer materials, which have the advantages of thermal stability, ozone resistance, ionizing radiation resistance, and flame retardancy.
Since silicone rubber materials can only show better bonding properties between similar molecular structures, the core rod sheath and the outer insulating sheds and shed grooves are made of the same silicone rubber material.
The hardware at both ends of the composite insulator forms the upper and lower electrodes and force transmission for it, and is convenient for connection with the hardware and wires on the tower.
We conduct strict quality inspection on each composite insulator before packing to ensure that the connection between the metal end and the core rod must be firm and reliable.

To overcome the challenges, Hbcrownwealth manufacturers focus on innovations in materials, structures, etc. Composite insulators have become an integral part of the power industry due to their unique properties. Here are some specific applications where they are particularly beneficial:
Transmission Lines: They are widely used in high voltage transmission lines to prevent arcing and flashover which can cause power outages and equipment damage.
Substations: Within substations, composite insulators serve as isolators, bushings, and surge arresters, providing insulation and protection against overvoltage conditions.
Electrical Equipment: They are used in circuit breakers, transformers, and switchgear to maintain electrical isolation and ensure the safe operation of these critical components.
Composite insulators are made of a combination of materials, usually consisting of a shell jacket made of polymer material and a core rod made of conductive material.
Our composite insulators are more than just insulation. They are mainly designed to withstand various harsh environmental conditions such as ultraviolet radiation, mechanical stress, and extreme cold and heat. Composite insulators prevent leakage, reduce maintenance costs and improve the reliability of power systems.
Glass Insulators: With high mechanical strength, glass insulators are not prone to surface cracking and have a long service life. Their brittle nature makes them prone to breakage under extreme conditions or physical shock.
Ceramic Insulators: They are highly praised for their excellent chemical and thermal stability and strong anti-aging properties. But they require laborious and expensive inspections, and they are more prone to accidents caused by lightning strikes.
Composite Insulators: Small size and light weight, easy to maintain and install, high mechanical strength, not easy to break, excellent anti-seismic and anti-fouling properties, suitable for various environments, relatively short production cycle, and highly consistent quality.
