Composite insulators consist of three parts: an insulating core rod, a silicon rod with a rubber sheath, and the connecting hardware at both ends.

Insulating core rods, also known as epoxy glass fiber drawn rods, serve as the skeletal structure for composite insulators. They support the hood, internal insulation, and connect the two terminal hardware, while also withstanding mechanical loads. They possess high tensile strength, typically exceeding 600 MPa, which is twice that of ordinary steel and 5 to 8 times that of porcelain. They also exhibit excellent dielectric properties and resistance to chemical erosion, as well as 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. They 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 good hydrophobicity and migration properties, as well as excellent resistance to corrosion, aging, and electrical insulation. Moreover, they offer high flashover voltages 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.
