Product feature:
Metal oxide arrester for transmission lines is a new type protection device for over-voltage,which has much more merits,such as:tiny power frequency flow current,reliable arcing suppressing,low weight,good pollution tolerance,good electrical erosion,anti-aging,small volume,not easily damaged normally free maintenance,convenient installation and can withstand multiple lightning,etc,and widely used in the transmission lines from lightning impulse,reducing lightning trip-out rate,particularly applicable to the area with frequent lightning activities,higher soil resistance,and also for the area difficult to be examined and sited.
