Glass Ground Insulators

The ground wire is a device that protects overhead transmission lines from lightning attacks, also known as lightning protection wire. The transmission line spans a vast area, and it is easy to be struck by lightning in the thunderstorm season, which will cause interruption of power transmission, which has become one of the main reasons for power outages in the power system. Installing overhead ground wires can reduce lightning accidents and improve the safety of line operations. Ground wire insulators are usually installed in the ground wire protection device in the transmission line. The ground wire insulator usually consists of two parts, the insulator, and the protective gap./

When the line is in normal operation, the ground wire insulator can protect the ground wire and insulate the ground wire from the iron tower and can reduce the loss of power transmission energy, and open the ground wire carrier communication. If there is an overvoltage on the ground wire, the protective gap of the ground wire insulator can realize conduction between the ground wire and the iron tower through discharge, so as to play various protective functions. Ground wire insulators can also be divided into three types: porcelain insulators, glass insulators, and composite insulators. Among them, the anti-aging performance of tempered glass insulators for ground wires is also very good. Since the dielectric constant of the glass material is between 7 and 8, the tempered glass insulators have a large main capacitance and a series of evenly distributed voltages. It is beneficial to reduce the voltage on the periphery of the insulator, and it is also beneficial to reduce radio interference and corona loss, thereby effectively prolonging the life of the glass insulator.
