Main Characteriestics & Features:

1. The insulating member of the porcelain insulator is made of an inorganic material alumina ceramic which has excellent aging resistance and chemical stability. The glass insulator is made of tempered glass as an insulator, assembled by cement glue and other metal hanging parts, and adopts the "hot tempering" process, which gives the glass surface layer a permanent prestress of 100-250 MPa, which increases the strength of the tempered glass. Increased thermal stability, enhanced aging resistance and extended life.
2. According to China's electromechanical performance tracking test of glass and porcelain insulators that have been running for 5 to 30 years, the service life of glass insulators depends on metal accessories. The service life of porcelain insulators depends on the insulation parts. Operating experience shows that glass insulators run 40a. The electromechanical performance does not change much, and the average life cycle of porcelain insulators is 15~25a.
3. The outer insulation of the composite insulator is made of organic material silicone rubber. It is easy to age under the conditions of corona discharge, ultraviolet radiation, humid environment, temperature change and chemical corrosion. It is necessary to observe the service life for a long time. Currently, the composite insulator is only With more than 20 years of operational experience, there is not enough data to support it. From the domestic and international operating experience, as long as the composite insulator can guarantee the quality of the factory, the service life of 10a is no problem.

1. LSR is a two-component liquid material divided into A component and B component. The operation of the mixer thoroughly mixes the A component and the B component in a precise 1:1 ratio. Because some products are colored, they are equipped with a color pump set and a color metering part. The A+B components, additives, colors, etc. are thoroughly mixed and then enter the plasticizing system.
2. The plasticizing screw has the functions of homogenization and mixing, and the mixture is injected into the hot mold through a screw, and the curing reaction of the silica gel occurs at a mold temperature of 170 to 200 °C. When using a cold runner system, it is worth noting that the runner is cold enough. In order to avoid leakage, the needle valve is mounted on the surface of the mold part, and the needle valve immediately closes the nozzle when the injection is completed.
