Composite Insulator Manufacturer

The composite insulator is composed of three parts: the insulating core rod, the silicon rod insulating sleeve, and the connecting hardware at both ends.

Insulating core rods, also known as epoxy glass fiber pulling rods, serve as the skeletal structure for composite insulators. They support the hood, internal insulation, and connect the two terminal fittings, while also withstanding mechanical loads. They boast a high tensile strength, typically exceeding 600 MPa, which is twice that of ordinary steel and 5 to 8 times that of porcelain materials. They also exhibit excellent dielectric properties, resistance to chemical erosion, and good resistance to bending fatigue, creep, and impact. Silicone rubber hoods primarily protect the core rod, shield against rain and snow, increase the creepage distance, and enhance the external insulation of the product. These hoods are made from high polymer silicone rubber, reinforced with flame retardants, anti-aging agents, coupling agents, and other fillers, cured under high temperature and pressure. They have excellent hydrophobicity and migration properties, as well as good resistance to corrosion, aging, and electrical insulation. Moreover, they possess high pollution flashover voltage and resistance to breakage, with a uniform voltage distribution. Compared to porcelain, their flashover voltage under the same conditions is more than twice that of porcelain.
