    69KV Porcelain Electronic Zinc Oxide Lightning Arrester With Double Sealing Structure

    Porcelain Metal-oxide Outdoor Lightning Arrester 69KV


    Introduction:


    Porcelain Surge Arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.

    Main features: It adopts double sealing structure, the core encapsulates by molded silicone rubber which completely solves the sealing problem of porcelain housed products.
    It has a two-way pressure release structure.
    Its core component ZnO varistor has good pressure ratio, consistency, large flow capacity and high reliability.


    Applications:


    1. Distribution networks

    2. Transmission line

    3. Substation

    4. Railway power station

    5. Alternator and electromotor
