Y5WZ-10/27 Station Type Porcelain Housing Zinc Oxide Arrester

Applicable Standards

Y5WZ-10/27 station type porcelain housing zinc oxide arrester is suitable for AC 220kV and below power generation, transmission, transformation and distribution systems, used to limit the amplitude of lightning and system internal operating overvoltages to specified levels. It is the basis for insulation coordination of all types of electrical equipment in power systems. The protection performance of the arrester determines the internal and external insulation indicators (short-time power frequency withstand voltage, lightning impulse withstand voltage and switching impulse withstand voltage, etc.) of all electrical equipment in the power system.

Y5WZ-6kV porcelain housing metal oxide arrester (station type porcelain housing zinc oxide arrester) is the best product among conventional arresters internationally, with excellent nonlinear volt-ampere characteristics, fast steep wave response and large current carrying capacity. The porcelain insulation housing of FAURE/Gaosuo Electric's porcelain housing arresters is formed by isostatic pressing, with high density and good electrical insulation. Equipped with unique sealing technology and pressure relief devices, it is safe and reliable, widely used in various power applications. It has long service life and good texture, making it an ideal product that combines durability and aesthetics. After China fully introduced this technology in the mid-1980s and through years of practical digestion, the performance of products from professional arrester manufacturers is now not far behind the best products from the United States, Japan and Western Europe. Products that truly meet all international requirements can also meet all requirements of international IEC standards.
