Air in coastal areas contains salt spray, which over long periods of time causes corrosion of external insulation components of power systems, posing a serious problem for high-voltage power transmission and conversion equipment. 330kV zinc oxide arrester manufactured by Shijiazhuang Heist Electric Co., Ltd. Features a ring voltage equalization structure to enhance anti-pollution protection and is specially designed for use in areas subject to heavy salt spray and industrial pollution.
The body of the equipment is made of composite silicone rubber, which is resistant to salt spray corrosion and has excellent anti-aging properties. It can maintain overall equipment performance after long-term use in humid and salty environments. Electrical networks in some coastal regions of Russia are exposed to salt spray year-round, and insulating parts of high-voltage equipment are susceptible to ground faults, requiring higher standards of protection against lightning rod contamination. This product uses a voltage equalization ring to optimize potential distribution, improve the operating condition of external insulation, and reduce the risk of failure caused by polluted environment. Backed by intelligent product design, Hyster Electric high voltage lightning protection equipment provides stable and reliable surge protection solutions for substations and power lines in coastal areas overseas.
