What Are Polymer Insulators?

Rod-shaped insulators are used for high-voltage power transmission lines. They can be used in areas with different pollution levels. They have the characteristics of light weight, small size, non-breakability, high tensile strength, and strong pollution performance.

This product can be widely used in high-voltage power transmission lines and can be applied to different pollution levels. It has the characteristics of light weight, small size, not easy to break, high tensile strength, and strong pollution performance.

There are at least two types of composite insulators

Composite insulators are composed of umbrella sleeves, core rods and metal fittings at both ends. For products of 110kV and below, there is no equalizing ring, and products of 220kV and above are equipped with 1-2 equalizing rings. Can also be equipped with pressure equalizing ring according to user needs.

1. Umbrella disc made of high molecular polymer with silicone rubber as base has good water repellency, corrosion resistance and aging resistance. It can effectively prevent the occurrence of pollution flashover accidents, reduce manual cleaning, and avoid zero-value maintenance, which provides a reliable guarantee for the safe operation of transmission lines.

2. The core rod is made of glass fiber reinforced resin rod, which has a high tensile strength (> 1100Mpa), which is about 1.5 to 2 times that of ordinary steel, and 3 to 5 times that of high-strength porcelain. In addition, the core rod also has good vibration resistance, creep resistance and fatigue fracture resistance.

3. Fittings and core rods are connected by non-damage mechanical crimping, which is the most advanced connection method in the world today. Its advantages are: the connection is safe and reliable, the compression stress distribution is uniform, and the integrity of the core fiber glass fiber bundle is not damaged, and the excellent characteristics of high tensile strength can be fully exerted.

4. The voltage equalizing ring has improved electric field distribution, reduces corona and radio interference, and protects the umbrella skirt from being burnt out during a strong arc. For composite insulators of high voltage level, the effect is more significant.

5. The composite insulator is compact in structure, small in size, and light in weight (1/7 to 1/10 of the same grade porcelain insulator string), has good elasticity, and does not require regular cleaning. Therefore, it not only brings great convenience to transportation and installation, but also greatly reduces the amount of maintenance and saves a lot of maintenance costs, reduces the labor intensity of workers, and also provides good conditions for accident maintenance and implementation of compact lines.

6. Composite insulators are produced using integral injection molding production processes. The umbrella cover has beautiful appearance, few interfaces, the core rod and the sheath are firmly and seamlessly bonded, and the internal insulation performance is good, which can avoid interface breakdown.

Rod-shaped Suspension Composite Insulator Model:

FXBW4-10 / 70, FXBW4-10 / 100, FXBW4-35 / 70, FXBW4-35 / 100, FXBW4-66 / 70, FXBW4-66 / 100, FXBW4-110 / 70, FXBW4-110 / 100, FXBW4- 110/120, FXBW4-220 / 70, FXBW4-220 / 100, FXBW4-220 / 120, FXBW4-220 / 160, FXBW4-330 / 100 ...

1. Products have been tested one by one and sampling tests according to the standards before leaving the factory. In order to prevent damage during transportation, they should be carefully checked one by one before installation. The surface area of the insulator umbrella disc (such as lack of glue, depression depth 1mm) area 0.2% of the total surface area of the insulator.

2. Do not use if the umbrella cover is torn or worn and the mandrel is exposed.

1. The insulators are packaged according to the provisions of JB / T9673.

2. Insulators are packed in sturdy, suitable-sized packaging cartons for easy transportation.

3. 220kV and below products are packed in cartons, 10kV products are packed with 6 products per box, and 35kV 220kV products are packed with 3 products per box. 330kV 750kV products are packed in round paper tubes, each tube contains one product. 330kV 750kV When packing, in order to better protect the product from damage, first use three radial support plates to fix the insulator, then install it in a round paper tube, and finally package the paper tube with plastic bags.

4. Each packing box contains a product certificate and 3 to 10 instructions for use are included with the shipment.

5.The pressure equalizing ring is packed in another carton. There are three pressure equalizing ring cartons for products of 220kV and below, and two pressure equalizing ring cartons for products of 330kV and above. ^] .
