The composite insulator is composed of three parts: an insulating mandrel rod, a silicone rod rubber umbrella sleeve and connecting fittings at both ends. The insulating mandrel is the abbreviation of epoxy resin glass fiber drawing rod, which is the skeleton of the composite insulator, which plays multiple roles such as supporting the umbrella sleeve, internal insulation, connecting the fittings at both ends, and bearing mechanical loads, and has high tensile strength, generally up to more than 600Mpa, which is 2 times that of ordinary steel, 5~8 times that of porcelain materials, and has good dielectric properties and chemical attack resistance, as well as good bending fatigue resistance, creep resistance and impact resistance. Silicone rubber umbrella cover mainly plays the role of protecting the mandrel rod, shielding rain and snow, increasing creepage distance and external insulation of the product, which is made of polymer silicone rubber as the matrix, supplemented by flame reta

The equalizing ring can improve the voltage distribution, and at the same time, the ring is discharged to the ground during the flashover, which can play a role in protecting the umbrella sleeve from being arc burned, and alleviate the aging of the umbrella sleeve at the live end. The high-voltage end of the 110kV product is equipped with a equalizing ring, but it is recommended to be equipped with equalizing rings at both ends in the multi-mine area; Products of 220kV and above voltage level have a voltage equalizing ring at the high voltage end and the grounding end.

35kV, 66kV, 110kV, 220kV windproof bias composite series products are suitable for high-voltage line hard jumpers, which can effectively prevent jumper wind deviation, and the wire dances with the wind, ensuring the insulation distance between phase and ground, also called hard jumper insulator, which eliminates the phenomenon of line tripping, wire arc burn, broken strands, and broken wires caused by jumpers. It solves the important hidden danger that the conductor dances with the wind and threatens the safe and stable operation of the overhead transmission line.

Composite tensile insulator is suitable for use in polluted areas, especially in heavily polluted areas, its high tensile strength, good anti-fouling performance, easy installation and use, etc., using a variety of fittings connection structure, and the line fittings are compactly connected.

The composite tensile insulating string is composed of composite insulators and energy-saving insulating tensile fittings, which has the advantages of compact structure, easy installation, reliable insulation, strong stain resistance and energy saving, and is deeply loved by the majority of users.

Composite pin insulators have high bending resistance, torsional strength, impact resistance, shock resistance and explosion-proof properties. The inner insulation is reliable, light weight, and easy to install, which is an ideal replacement for traditional porcelain insulators.

The composite cross arm insulator can effectively use the narrow corridor to open voltage power transmission, is suitable for the technical transformation of the urban network, can reduce the height of the tower, can save a lot of manpower, material and financial resources, due to its high bending strength, can prevent the porcelain cross arm is prone to cascade fracture accidents, is the porcelain cross arm can not replace the product; Small size, light weight, shockproof, strong impact resistance, no need for manual cleaning, to provide guarantee for safe operation.

The composite pillar insulator has good bending resistance, strong anti-fouling ability, strong impact resistance, good shockproof and anti-brittle breaking performance, small size, light weight, easy installation, maintenance-free, no manual cleaning, and interchangeability with porcelain.

The composite dry casing is a kind of wall casing, its inner insulation is made of insulating material, and the outer insulation (silicone rubber umbrella skirt) is made of high-temperature vulcanized silicone rubber, which has good stain resistance. The seismic performance and explosion-proof performance are in line with the development trend of oil-free and miniaturization in the power sector, and are high-voltage power transmission and transformation products that meet the transformation of urban and rural power grids.
