National standard code: FXBW4-220/160
Other manufacturers' codes for similar products: The composite suspension insulator FXBW4-220/160 produced by our company is completely produced according to national standards, with the same model number as other manufacturers.
A composite insulator consists of three parts: an insulation core rod, a silicone rubber umbrella sleeve, and connecting fittings at both ends.
Insulation core rod is the abbreviation for epoxy resin glass fiber pull rod. It is the skeleton of composite insulators, which plays multiple roles such as supporting umbrella sleeves, internal insulation, connecting two end fittings, and bearing mechanical loads. It has high tensile strength, generally up to 600Mpa or more, which is twice that of ordinary steel and 5-8 times that of ceramic materials. It also has good dielectric properties and chemical resistance, as well as good resistance to bending fatigue, creep and impact. The silicone rubber umbrella cover mainly plays the role of protecting the core rod, shielding rain and snow, increasing the creepage distance and external insulation of the product. It is made of high polymer silicone rubber as the matrix, supplemented with flame retardant, anti-aging agent, coupling agent and other fillers through high-temperature and high-pressure vulcanization. It has good hydrophobicity and mobility, as well as good corrosion resistance, anti-aging, electrical insulation and other properties. And it has high pollution flashover voltage and crush resistance, with uniform voltage distribution. Compared with porcelain, its flashover voltage under the same conditions is more than twice that of porcelain

Performance characteristics of the product
Small in size and light in weight, it is about 1/5~1/9 of the same voltage level ceramic insulator, making it easy to transport and install.
Composite insulators have high mechanical strength, reliable structure, stable performance, and a large margin for safe operation, providing guarantees for the safe operation of power lines.
The electrical performance of composite insulators is superior. Silicone rubber umbrellas have good hydrophobicity and mobility, good pollution resistance, strong anti pollution flashover ability, and can operate safely in heavily polluted areas without manual cleaning, and can be maintained without measuring zero values.
Composite insulators have the characteristics of acid and alkali resistance, heat aging resistance, electrical resistance, good sealing performance, and can ensure that their internal insulation is not affected by moisture.
Composite insulators have good anti brittleness performance, strong shock resistance, and will not cause brittle fracture accidents.
Composite insulators are interchangeable and can be used interchangeably with porcelain and other insulators.
