Zero value self-breaking, easy to detect
Tempered glass insulators have the characteristics of zero-value self-breaking. As long as the observation is on the ground or on a helicopter, there is no need to climb the poles to detect piece by piece, which reduces the labor intensity of workers.
The products introduced into the production line have an annual operating self-breaking rate of 0.02-0.04%, which can save line maintenance costs. Good arc and vibration resistance
The new surface of the glass insulator burned by lightning during operation is still a smooth glass body with a toughened internal stress protection layer, so it still maintains sufficient insulation performance and mechanical strength.
On the 500kv line, there have been many disasters caused by the movement of the wire running on ice. The glass insulator after the wire movement has been tested, and the electromechanical performance has not been attenuated.
Good self-cleaning performance and not easy to age
According to the general report of the electric power department, the glass insulators are not easy to accumulate dirt and are easy to clean. The glass insulators running on the southern line are washed clean after rain.
Regular samples of glass insulators on lines in typical regions are taken to determine their electromechanical performance after operation. The accumulated data show that the electromechanical properties of glass insulators after 35 years of operation are basically the same as those at the factory without aging.
The main capacity is large, the voltage distribution in the string is uniform, and the dielectric constant of the glass is 7-8, so that the tempered glass insulator has a large main capacitance and the voltage distribution in the string is uniform, which is beneficial to reduce the load on the insulator near the wire side and the grounding side. Voltage, so as to achieve the purpose of reducing radio interference, reducing corona loss and extending the life of glass insulators, operation practice has proved this.
