Detailed description of fxbw4-10 / 100 composite rod suspension insulator:
Composite insulator is composed of three parts: insulating core rod, silicon rod rubber umbrella sleeve and connecting hardware at both ends.
Insulating core rod is the abbreviation of epoxy glass fiber pull rod. It is the skeleton of composite insulator. It supports the umbrella cover, internal insulation, connecting the fittings at both ends, and bears the mechanical load. It has high tensile strength, generally up to more than 600MPa, 2 times of ordinary steel, 5-8 times of porcelain, and has good dielectric properties and chemical resistance, It also has good bending fatigue resistance, creep resistance and impact resistance. The silicone rubber umbrella covers mainly protect the mandrel, cover the rain and snow, increase the creepage distance and the external insulation of products. It is made of high molecular polymer silicone rubber as the base, supplemented with flame retardant, anti-aging agent, coupling agent and other fillers, which is sulfurized by high temperature and high pressure. It has good hydrophobicity and mobility, and good corrosion resistance, aging resistance, electrical insulation and other properties. Moreover, it has high pollution flashover voltage and crushing resistance, and the voltage distribution is even. Compared with porcelain, its flashover voltage is more than 2 times of that of porcelain under the same conditions.

Product performance characteristics
It is small in size and light in weight, about 1 / 5 ~ 1 / 9 of porcelain insulator of the same voltage level, which is convenient for transportation and installation.
Composite insulator has the advantages of high strength, reliable structure, stable performance and large margin of safe operation, which guarantees the safe operation of the line.
The electrical performance of composite insulator is superior. The silicone rubber umbrella has good hydrophobicity and mobility, good pollution resistance and strong anti pollution flashover ability. It can operate safely in heavily polluted areas without manual cleaning and zero value maintenance.
The composite insulator has the characteristics of acid resistance, alkali resistance, heat aging resistance, electrical resistance, good sealing performance, and can ensure that its internal insulation is not affected by moisture.
The composite insulator has good embrittlement resistance, strong shock resistance and no brittle fracture accident.
The composite insulator is interchangeable and can be used interchangeably with porcelain and other insulators.
