Composite Housed Gapless Zinc Oxide ArresterThe gapless zinc oxide arrester adopts zinc oxide resistor as the core component, which has excellent nonlinear volt-ampere characteristics, fast steep wave and large circulation capacity. The composite housed gapless zinc oxide arrester is molded by integral silicone rubber, which has the advantages of small volume, light weight, pollution resistance, free-cleaning, explosion prevention and vibration resistance. It is an updated product of porcelain-sheathed lightning arrester. Service environment of product: the power frequency is 48-62 Hz, the temperature is 40°C to +40°C, the altitude does not exceed 1,000 m, and the earthquake intensity is VII or below. Executive standard of product: GB11032-2000 Gapless Metal Oxide Arrester for AC System and JB/T8952-2005 Composite Housed Gapless Metal Oxide Arrester for AC System. Main technical parameters
