The composite insulator is composed of three parts: an insulating core rod, a silicon rod with a rubber sheath, and the connecting hardware at both ends.

Insulating core rod, also known as the epoxy glass fiber pulling rod, serves as the framework for composite insulators, supporting the hood, inner insulation, connecting hardware at both ends, and withstanding mechanical loads. It boasts an exceptional tensile strength, typically exceeding 600MPa, which is twice that of ordinary steel and 5 to 8 times that of ceramic materials. It also exhibits excellent dielectric properties and resistance to chemical erosion, as well as good resistance to bending fatigue, creep, and impact. Silicone rubber hood primarily protects the core rod, shields against rain and snow, increases the creepage distance, and enhances the product's external insulation. It is made from high polymer silicone rubber, reinforced with flame retardants, anti-aging agents, coupling agents, and other fillers through high-temperature, high-pressure vulcanization. It offers good hydrophobicity and migration properties, along with excellent resistance to corrosion, aging, and electrical insulation. Moreover, it boasts a high flashover voltage and resistance to breakage, with uniform voltage distribution. Compared to porcelain, its flashover voltage under the same conditions is over twice that of porcelain.

Product Performance Features

Small in size, light in weight, about 1/5 to 1/9 of the same voltage grade porcelain insulators, convenient for transportation and installation.

Composite insulators feature high mechanical strength, reliable structure, stable performance, and ample safety margin for operation, providing assurance for both the line and safe operation.

The composite insulator boasts superior electrical properties. The silicone rubber canopy ensures excellent hydrophobicity and migration resistance, excellent dirt resistance, strong anti-tracking ability, and can operate safely in heavily polluted areas without the need for manual cleaning, thereby eliminating the need for zero-value maintenance checks.

Composite insulators feature resistance to acids and alkalis, heat aging, and electrical breakdown, excellent sealing properties, and ensure internal insulation remains dry.

The composite insulator boasts excellent anti-fracture properties, strong vibration resistance, and will not experience brittle fracture accidents.

Composite insulators are interchangeable and can be used in place of porcelain insulators and others.
