Application The ZnO arrester is mainly used to protect distribution transformer,cable connector and electric equipment from being damaged by lightning impulse voltage and oper-ated over-voltage. • 0 oxide arrester is the most advanced over-voltage protector on the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional silicon carbide arrester, this prescription of the product improves greatly the volt-Ampere characteristics of the resister disc and increased through- current capability at over voltage so as to bring a rad Ical-chages for the characteristics of the arresters. 1. Ambient temperature:-40°C — +40°C; 2. Altitude: up to 1000m; 3. AC system frequency 50Hz or 60Hz; 4. Maximum wind velocity: 35m/s; 5. Earthquake intensity: 8 degree; 6. The filthy area should be given clear indication Technical Standar. All technical performances are in compliance with GB 11030-2000, IEC 60099-4, IEC37-199/CDV..
