  護層保護器的專用裝置,防止雷擊及感應過電壓對電纜護層的危害.護層保護器并接于高壓電纜護層與地之間,用螺栓和電纜護層連接,護層保護器即投入使用.安裝時,高壓出線端端部引線拉力不應大于145N.連接導線的絕緣水平不應低于所保護電纜外護層絕緣水平,且連接回路應盡可能短.裝置須可靠接地.護層保護器采用ZnO壓敏電阻作為保護元件,無串聯間隙,保護特性好,具有優良的非線性伏安特性曲線.既具有瓷套式金屬氧化物避雷器的優點,還具有電氣絕緣性能好、介電強度高、抗漏痕、抗電蝕、耐熱、耐寒、耐老化、防爆等優點及良好的化學穩定性、憎水性、密封性.我們生產的可廣泛應用于單芯電力電纜線路中,用來保護電纜的金屬護層免受各種過電壓的危害.為更好的適應市場的需求,方便用戶現場安裝使用,我公司進一步開發了電纜護層直接接地箱、護層保護器和交叉互聯護層保護器等幾種形式的護層接地裝置.我公司生產的各種電纜護層接地裝置已廣泛應用于全國各個電氣化鐵路系統,取得了良好的運行經驗.
