Before writing this article, after seeing those towering transmission towers, I couldn't help but feel delighted by these power facilities. At the same time, a question arose in my mind: With so many conductors transmitting enormous amounts of electrical energy day and night, how can we ensure that these high-voltage…

Insulators are insulating bodies used to support conductors. They are mostly applied for insulating external live conductors in overhead transmission and distribution lines, busbars in power plants and substations, and various electrical equipment. They are generally composed of insulating parts (such as glass or cer…

Under normal power frequency voltage, especially during prolonged high-temperature, high-humidity weather or pollution, flashover may occur on HTV silicone rubber composite insulators. The discharge mechanism of hydrophobic composite insulators differs from that of hydrophilic porcelain and glass insulators. When the…

During the installation of building-related pipelines, it is sometimes unavoidable to pass pipelines through walls. In such cases, wall bushings must be used at the relevant locations to protect the pipelines from the pressure of the building structure. However, during the lowering operation, a great deal of technica…
