1.The porcelain lightning arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage.
2 Under the circumstance of normal operating voltage,the current go through the porcelain lighting arrester is just on micro ampere degree. When suffered from over-voltage,the excellent nonlinear characteristic of the porcelain lightning arrester will make the current that run through the arrester increase to several thousand amperse,While the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments from the damage caused by the over-voltage.
3.Normal service conditions
The ambient air temperatures is no higher than +40°C, no lower than -40°C.
The altitude above sea level does not exceed 1000-2000m(the altiplanoarea should be indicated when order).
