Their materials directly determine the safety and reliability of the wires. Traditional iron-porcelain cross arms have experienced matching problems after years of use. In transmission projects, cross arms support insulators and wires. Compared with traditional iron-porcelain crossarms, they have eight…
With gapless structure, ultra-fast response, large current carrying capacity, strong aging resistance and maintenance-free performance, metal oxide surge arresters have completely replaced traditional arrester products. Today, they are standard overvoltage protection equipment widely adopted in power grids, industrial parks, building…
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…
