The true origin of glass insulators
Sep 04, 2018

Glass is also called dewaxed glass in ancient times. Glass is a material that is transparent, strong and hard, and airtight. Glass is chemically inert in everyday environments and does not interact with organisms, so it is very versatile. Glass is generally insoluble in acid (exception: hydrofluoric acid reacts with glass to form SiF, which causes corrosion of the glass); but is soluble in strong bases such as barium hydroxide. Glass is an amorphous supercooled liquid. The melted glass cools rapidly, and each molecule forms glass because it does not have enough time to form crystals. Glass in ancient times refers to a kind of natural jade, also called water jade, but not the current glass.

Insulators are a special type of insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used in utility poles. Later, one end of the high-voltage high-voltage wire connection tower was hung with a large number of disk-shaped insulators. In order to increase the creepage distance, it is usually made of glass or ceramic, which is called an insulator. Insulators play two fundamental roles in overhead transmission lines, namely supporting the conductors and preventing current from returning to the ground. These two functions must be ensured. The insulators should not fail due to various electromechanical stresses caused by changes in environmental and electrical load conditions. Otherwise, the insulator will not have a major effect, which will damage the use and operating life of the entire line.

Glass and insulator are combined with glass insulators, and glass insulators can be used to eliminate the periodic periodic preventive test of the insulator during operation. This is because every damage to the tempered glass will cause damage to the insulator, which is easy for the operator to find when patrolling. When the insulator is damaged, the glass fragments near the steel cap and the iron foot are stuck, and the mechanical strength of the remaining portion of the insulator is sufficient to prevent the insulator string from breaking off.
