AC surge arrester YH10W-18

1. The ambient temperature is not high than +40 celsius and not lower than -40 celsius. 2. The altitude above sea level do not exceed 1000-2000m.(Altiplano area should be indicated when order.) 3. The frequency in AC system is 50Hz or 60Hz. 4. Power frequency voltage which has been bearing on arrester for a long time do not exceed continuous operating voltage. 5. Max. wind speed do not exceed 35m/s. 6. Apply to the area where earthquake intensity is not exceed 8 degree. 7. The filthy area should be indicated before. 1. The low weight facilitates installation and permits erection in limited spaces and at almost all angles. 2. No continuous current and low current impulse residual voltage. 3. Excellent pollution and short circuit performance. 4. Safe to touch when energised by accident. 5. Stable U-I characteristics,even after multiple strikes. 6. Resistant to UV,ozone,chemicals,mechanical abuse. 7. Fully qualified following IEC60099-4.
