Importance of Surge Arrester Leakage Current Measurement Measuring the leakage current of surge arresters is one of the most important routine preventive tests in power operation and maintenance. It is the most direct and effective method to judge whether the…
When we built the power grid, glass fiber crossarms were an important part of the tower. They fix large wires and insulators and keep the entire power system working properly. Most common cross arms are made of metal. They do…
Basic Overview of Surge Protectors A surge protector, also widely known as a lightning protector or overvoltage protector, is an essential safety device used in power distribution systems, industrial automation, communication computer rooms, and household electrical circuits. Many people only…
In the construction and operation of 10kV high‑voltage transmission and distribution networks, surge arresters play an irreplaceable core role in safeguarding power lines, transformers, switch cabinets and terminal electrical equipment. Different from ordinary low‑voltage lightning protection products, specially customized 10kV…
Rural power grid projects used to face big troubles. In past years, when workers upgraded power lines in villages, they only focused on setting up wires to supply electricity and tried to cut costs as much as possible. They mainly…
I. Material Benefits of the 66 kV High-Voltage(FRP) Cross Arm The appearance of FRP cross arms is basically the same as that of traditional composite material ones. But, in comparison with galvanized steel cross arms, FRP cross arms are only…
For 33 kV outdoor transmission lines, crossarms are critical for supporting the line’s conductors, and their performance directly impacts the overall safety and the line’s serviceability. Crossarms constructed using conventional iron undergoes accelerated corrosion due to exposure to atmosphere, which…
