Outdoor Porcelain Surge Protector Lightning Protection

 

Application

         The Outdoor Pocerlain Surge Protector Lightning Protection is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage.

 

Keystone

         The Outdoor Pocerlain Surge Protector Lightning Protection is the most advanced over-voltage protector in the word. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with conventional silicon carbide arrester, this prescriptions of the product improves greatly the volt-Ampere characteristic of the resistor disc and increased through-current capability at over-voltage so as to bring a rid I cal-changes for the characteristics of the arrester.

        Under the circumstance of normal operating voltage, the current is through the arrester I just on microampere degree. When suffered from over-voltage, the arrester is excellent nonlinear character is tics will make the current through the arrester increase to several thousand amperes, While the arrester will be under the circulating state and release over-voltage energy so as to protecting the power transmission equipments against the damage caused by the over-voltage.

  

Normal service conditions
