        ■ 验收及维护 Acceptance and maintenance
        每只干式高于穿墙套管出厂前进行了工频耐压、局部放电测量、介质损耗因数测量及末屏耐压试验。到现场后,可以按BG50150《电气装置安装工程 电气设备交接试验标准》进行。干式高压穿墙套管基本不需要维护,每2~3年测量一次电容量及介质损耗因数即可。
        Every dry type high voltage wall bushing has passed the tests including poewr frequency withstand voltage,partial discharge,dielectric loss factor,terminal withstand voltage before leaving the factory. We follow up GB50150 《Standard for hand-over test of electric equipment electric equipment installation engineering》when the products are handed over. In generally,the products need no maintenance basically.It is enough to check the primary winding capacity and dielectic loss factor every 2~3 years.
        ■ 运输及安装 Transportation and installation
        运输时用防震材料包装,防止剧烈震动。
        吊装时应防止硅橡胶伞裙受损。
        出厂文件包括:产品合格证、试验报告和产品说明书,均放入包装箱内,与产品一起运输。
        安装好后应将干式高压穿墙套管的末屏引线可靠接地。
        The products should be packed by shockproof material when they are transported.
        Pay attention to the silicon rubber umbrelas when the products are suspended.
        Documents:certificate,test report,product manual.They should be put into packing box with the products.
        Please earth reliably the terminal of the products after installing.
        ■ 订货须知 Notice for order
