330kV Lightning Surge Arrester,
0.22kV Surge Arrester In Transformer,
Compound Lightning Surge Arrester
The composite sheathed metal oxide arrester is a comprehensive scientific research result combining the technical advantages of organic insulating materials and porcelain sheathed arresters. It not only has the advantages of porcelain sheathed arresters, but also has good electrical insulation performance, high dielectric strength, anti-leakage tracking, and high resistance. Low temperature, wind and sand resistance, aging resistance, explosion-proof, good chemical stability, water repellency and other advantages. The outer jacket is made of high-quality silicone rubber, and is formed at one time by the integral molding and vulcanization process, with good sealing performance and long product life. The products are designed and manufactured in strict accordance with GB 11032 and other standards, and are at the leading level of similar products in China. Products are widely used in major projects of the State Grid and Southern Power Grid, such as: National Grid 1000kV Jindongnan-Nanyang-Jingmen UHV AC Test Demonstration Project Jindongnan 1000kV UHV Substation, State Grid 1000kV Jindongnan-Nanyang-Jingmen UHV AC Test Demonstration Project Nanyang 1000kV switch station expansion, State Grid ±800kV Hami-Zhengzhou UHV DC Transmission Project Hami South Converter Station, State Grid 750kV Lanzhou East Substation, State Grid 500kV Beijing Shunyi Substation, State Grid 750kV Gansu Baiyin Substation, State Grid 750kV Shaanxi Baoji Substation, State Grid 750kV Shazhou Substation, State Grid 750kV Qinghai Qaidam Substation, 500kV Baoji-Deyang DC Transmission Project, Southern Power Grid EHV 500kV Hechi Substation DC Ice Melting Project, Guizhou Power Grid 500kV Anshun Substation DC Major projects such as ice melting and 330kV Samsung substation in Xi'an High-tech Zone have reliable protection and stable operation.
