Composite Sway Insulator FXBW4-110 70

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 framework for composite insulators, supporting the hood, internal insulation, connecting hardware at both ends, and bearing mechanical loads. They offer high tensile strength, typically exceeding 600 MPa, which is twice that of ordinary steel and 5 to 8 times that of porcelain. They also possess excellent dielectric properties and resistance to chemical erosion, as well as good resistance to bending fatigue, creep, and impact. Silicon rubber hoods primarily protect the core rods, shield against rain and snow, increase the creepage distance, and enhance the external insulation of the product. Made from high polymer silicone rubber with flame retardants, anti-aging agents, and coupling agents as fillers, they are vulcanized under high temperature and pressure. They exhibit good hydrophobicity, migration resistance, and excellent resistance to corrosion, aging, and electrical insulation. Moreover, they have a high flashover voltage and fragmentation resistance, with a uniform voltage distribution. Compared to porcelain, their flashover voltage under the same conditions is more than twice that of porcelain.
