Porcelain Lightning Arrester

Type: Porcelain Lightning Arrester (zinc oxide arrester) Y5W-6 are mainly used to keep the amplitude of lighting impulse withstand voltage and switching impulse withstand voltage to the prescribed level. Condition of Use: 1. Ambient air temperature within the range of -40 Celsius degree to +40 Celsius degree; 2. Altitude above sea level not exceeding 2,000m; 3. Frequency of the A.C. power supply being 50Hz or 60Hz; 4. Power frequency voltage applied continuously between the terminals of the arrester not exceeding its continuous operating voltage; 5. Maximum wind speed not exceeding 35m/s; 6. The earthquake intensity not exceeding 7 degrees.
