Glass insulators, it made of glass, and allowed to support the wire insulation device.

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 to be.

Due to the transparency of the glass, in the shape of test it is easy to find small cracks and a variety of internal defects and damage. Electromechanical properties of tempered glass is much higher than porcelain manufacture the same type of insulator, and its size and weight is much smaller than the porcelain insulators.

Glass insulators, raw materials for the manufacture of glass insulators, porcelain manufacture than the raw materials used in more stable power, stable electrical and mechanical characteristics of glass to create a good condition.
