          產品特點Product Features

          ZW20A-12采用成熟的箱式密封結構,內部充以SF6氣體,具有良好的密封性能,是一種免維護產品。其彈簧操作機構采用直動傳動和多級脫扣系統,動作可靠性高;配備航空插座作二次電氣連接、便于與智能化控制器相結合。
          1. 操作靈活,方便:本產品為電動儲能、電動分合,同時具有手動儲能、手動分合;
          2. 開斷性能優越:開斷額定短路電流達30次;
          3. 操作功率小,可靠性高:全新設計的小型電動彈簧機構,機件數目和操作功都降低到最低水平;
          4. 安裝方式靈活:可采用柱上吊裝或坐裝安裝方式;
          5. 獨特的進出線方式:采用硅橡膠套管,使接線端子之間絕緣距離充裕,外絕緣特性優良;
          6. 使用安全:在箱體頂部安裝有防爆裝置,即使發生意外的內部故障,也不會有高溫氣體或飛濺物泄漏出來。
          ZW20A-12 uses better box-type seal structure. Interior filled with SF6 gas, with good sealing performance, and maintenance-free, the spring operating mechanic uses direct drive transmission system and multi-stage release, it has the high operating reliability; with secondary aerial socket for the electrical connection with the intelligent controller combination.
          1. Flexible operation, this product is the power storage with hand-operated and automatic electric operation;
          2. Superior breaking advantage: breaking short current can reach 30 times;
          3. Small operation power with the high reliability; all newly-designed small size electric spring mechanism, the operation power can be decrease at lowest level;
          4. Flexible installation: it can be placed on the column or hung on the column;
          5. Unique in-out way of cables: using bushing to expand the insulation space between the terminals, the unique insulation characteristics;
          6. Safety utilization: installation the explosion-proof device on the top of the cabinet. The high temperature gas or spatter will not be leak, even if there is accident inside.
