What are the advantages of glass insulators?

Glass insulator is used to support the wire and make it insulated device, it is made of glass, currently used in the route is widely toughened glass insulator. It is generally made of glass and porcelain, and is one of the key components of high-voltage transmission lines, and its performance directly affects the operation safety of the entire transmission line. Glass insulators are widely used because of the characteristics of zero self-breaking and easy maintenance. Now let's talk about the advantages of glass insulators.

(1) High mechanical strength, 1 to 2 times higher than the mechanical strength of porcelain insulators.

(2) The performance is stable and not easy to age, and the electrical performance is higher than that of porcelain insulator.

(3) Fewer production processes, short production cycle, easy to mechanized, automated production, high production efficiency

(4) Due to the transparency of glass insulators, it is easy to find small cracks and various internal defects or damage during external inspection.

(5) When the glass body of the insulator has various defects, the glass will automatically break, which is called "self-breaking". After the insulator is broken, the iron cap hammer still maintains a certain mechanical strength and is suspended on the line, and the line can still continue to run. When line inspectors patrol the line, it is easy to find self-broken insulators, and timely replacement of new insulators. Because the glass insulator has this "self-breaking" characteristic, it is unnecessary to carry out preventive tests on the insulator during on-line operation, which brings great convenience to the operation.
