Composite insulators Composite insulators have an overall rod-shaped design, compact structure, high quality, and weight that is 1/10 of the same grade porcelain and glass insulators. They are extremely convenient to transport and install, with high mechanical tensile load, large span and compact lines. The pollution flashover voltage is 30%-50% higher than that of porcelain and glass insulators of the same grade. There is three stability at -60 degrees to +200 degrees; the non-breakdown design is adopted, and there is no need to measure the zero value during operation.

1) Excellent pollution resistance. The surface of the silicone rubber sheath material is not only hydrophobic when new, but also temporarily restores its hydrophobicity under the operating conditions of the line. Water forms water droplets on the surface of the material, and the very fine film of the silicone rubber liquid basically engulfs the dirt, thereby suppressing the surface resistance of ionic substances at high voltages, reducing leakage current, and increasing pollution flashover voltage. This performance can maintain the reliability of energy transmission even when the silicone rubber material is aged, significantly reducing the cleaning and maintenance costs of insulators.

2) Excellent resistance to ultraviolet rays, corrosion resistance, no marks on Xiamen waste recycling

3) Small size and light weight The weight of 110kv/100kn composite long rod insulator is only 12% of the corresponding 70kn porcelain insulator. Such light weight greatly saves the need for cranes and is particularly suitable for emergency repairs of lines and the erection and maintenance of mountainous lines that are inaccessible to transportation tools; it can simplify the span of poles and towers (reduce the number of poles and towers); and provides conditions for the development of compact lines.

4) Production and delivery time is much shorter than porcelain insulators

5) No need for insulation resistance zero value detection

6) No brittleness This feature is not only convenient for installation and transportation, but also makes its arc tolerance much higher than that of porcelain insulator washing machine.
