      詳細信息
           交流輸電線路用復合外套避雷器是一種性能優異的過電壓保護設備,廣泛用于保護輸電線路,尤其是在雷電活動頻繁、土壤電阻率較大、巡線困難的山區,可大大降低輸電線路的雷害事故。
      線路避雷器可分帶串聯間隙和無間隙兩類,帶串聯間隙避雷器又可分為純空氣間隙和絕緣子間隙兩種。

      產品有如下特點:
             ⑴體積小、重量輕、便于懸掛安裝;
            ⑵采用可靠的密封結構設計,密封性能好、防潮、防爆、免維護;
            ⑶外絕緣采用優質、進口雙組份液態硅橡膠一次注射成型工藝,憎水性強、耐污性能好、耐電蝕、抗老化、撕裂強度高、耐碰撞、運輸無破損;
            ⑷帶串聯間隙線路避雷器,因其間隙隔離,電阻片運行負荷極輕,運行維護工作量極??;
            ⑸散熱性能好、防止電阻片老化;
            ⑹機械強度高;
            ⑺可承受多重雷擊,工作壽命長;
            ⑻獨特的內絕緣式設計給計數器安裝提供方便。

            表1.110kVMOA的技術參數見下表:


      2014725105026-1

       
             AC transmission line arresters composite jacket is an excellent over-voltage protection devices are widely used to protect transmission lines, especially in the frequent lightning activity, soil resistivity greater difficulty mountain patrol line, can greatly reduce the transmission line lightning damage accident.
            Line arrester with series gap can be divided into two groups with and without gaps, with a series of pure air gap arrester can be divided into two kinds of gaps and insulator gap.

            The product has the following characteristics:
            ⑴ small size, light weight, easy to install suspension;
            ⑵ using reliable sealing structure design, good sealing performance, moisture-proof, maintenance-free;
            ⑶ external insulation using high-quality, imported a two-component liquid silicone rubber injection molding process, hydrophobicity, good stain resistance, resistance to corrosion, aging resistance, high tear strength, resistance to impact, transport without damage;
            ⑷ line arrester with series gap, because the gap isolation resistor very light load operation, operation and maintenance workload minimal;
            ⑸ good heat dissipation performance, prevent aging resistors;
            ⑹ high mechanical strength;
            ⑺ can withstand multiple lightning strikes, long working life;
            ⑻ unique design to counter the insulation provided for easy installation.
