Real origin of glass insulators

    Due to the high mechanical strength of the glass insulator surface, the surface is not easy to crack occur. Electric strength of the glass is generally unchanged during the entire run, and the aging process is much slower than the porcelain should, therefore glass insulators from damage mainly due to retirement, occurred in the operation of the first year, but the porcelain insulators only running a few flaws After only beginning to discover.

    Glass in ancient glass, also known as dewaxing. Glass is a transparent, strength and hardness is high, impermeable material. Glass is chemically inert in the everyday environment, it will not work with biological, therefore very versatile. Glass generally insoluble in acids (exception: hydrofluoric acid reacts with the glass SiF, leading to corrosion of the glass); but soluble in strong base, such as cesium hydroxide. Glass is an amorphous supercooled liquid. Melting glass is rapidly cooled, each molecule because there is not enough time to form crystals formed glass. Glass in ancient times and refers to a natural jade, also called drop of water, but not now in the glass.

    Insulator is a special insulation control can play an important role in the overhead power transmission lines. Early years insulator used for poles, slowly developed in the high-pressure end of the wire connecting the tower to hang a lot of disk-shaped insulator, it is to increase the creepage distance, usually made of glass or ceramic, called insulators. Insulators for overhead transmission line plays two fundamental role, namely supporting wire and prevent current back to land, these two actions must be guaranteed, the insulator should not change because of various electrical and mechanical stress caused by environmental and electrical load conditions occur and fail, Otherwise, it will not have a significant insulator effect, it will damage the use and operating life of the entire line.

    Combined with glass and insulators out of glass insulators, glass insulators, regular preventive tests can cancel charged during operation of insulators. This is because the glass will cause damage for each damaged insulators, operating personnel at the patrol line is very easy to find it. When the insulator is damaged, the steel cap iron and glass shards near the foot was stuck, mechanical strength sufficient to prevent the remaining portion of the insulator insulator strings broken off.
