This composite housing zinc oxide surge arrester, especially the one with series gaps designed for line applications within the 13 - 54kV range, plays a unique role. When overvoltage appears in the line system, the series gaps work in coordination with the main body of the arrester. The gaps first provide an initial insulation breakdown path under certain overvoltage conditions, and then the arrester promptly conducts the excessive voltage energy to the ground. This effectively protects line insulators, conductors, and other crucial components from potential damage, ensuring the continuous and stable operation of the power transmission and distribution lines.
The 13 - 54kV Surge Arrester For Lines has notable features. It offers reliable overvoltage protection, able to swiftly respond to sudden voltage spikes. With sufficient power frequency withstand voltage and strong lightning impulse withstand voltage tailored to the line's electrical characteristics, it can endure various electrical disturbances commonly encountered on the lines. Moreover, its design with series gaps enhances its ability to handle different levels of overvoltage more precisely. It also has good thermal stability and mechanical strength to guarantee dependable operation under diverse working conditions outdoors along the lines.
