镀锌金属线槽作为电缆电气线路的外露及可导电部分，必须接地才可靠，山东电缆桥架在施工中应该正确的选择跨接接地线截面，并做好其连接，使得各个关节点之间形成有效可靠完好的链接。同时必须保证与接地干线的可靠连接。

Galvanized metal trough as cable electrical wiring of the leakage and electrically conductive parts, must be grounded to reliable, shandong cable bridge in construction should be the right choice jumper grounding line cross section, and make the connection, makes the link of each joint point between an effective and reliable in good condition. At the same time must ensure that the connection to a reliable grounding line.

镀锌金属线槽安装使用必须在正确的室内环境中，应该确保室内环境的干燥和不易受到机械损害，但是我们必须明白的一点就是对于有严重腐蚀的场所不应该采用。

Galvanized metal trough installation must be in the right indoor environment, should ensure that the indoor environment of the dry and less susceptible to mechanical damage, but we must understand that for a place with severe corrosion should not be used.

同一回路的所有相线和中性线，应敷设在同一金属线槽内。同一路径无防干扰要求的线路，可敷设于同一金属线槽内，线槽内电线或电缆的总截面（包括外护层）不应超过线槽内截面的20％，载流导线不宜超过30根。控制、信号或与其相类似的线路，电线或电缆的总截向下应超过线槽内截面的50％，电线或电缆根数下限；

All of the same loop phase line and neutral line, should be equipped in the same metal trough. The same path without the requirement of interference lines, can be equipped on the same metal trough, trough the total wire or cable cross section (including outer sheath) should not exceed 20% of the line groove section, current-carrying wire should not be more than 30 roots. Control, signal, or similar lines, and its total wire or cable should be cut down by more than 50% of the line groove section, the number of wire or cable floor;

镀锌金属线槽垂直或倾斜安装时，应采取措施防止电线或电缆在线槽内移动。4.由镀锌金属线槽引出的线路，可采用金属管，硬质塑料管、半硬塑料管、金属软管或电缆等布线方式。电线或电缆在引出部分不得遭受损伤；

Galvanized metal trough vertical or inclined installation time, measures should be taken to prevent the wire or cable groove moving online. 4. Line arise out of the galvanized metal trough, can use metal, hard plastic tube, half-hard plastic pipe, metal hose, or cable wiring. Wire or cable in lead part shall not suffer injury;

有的金属线槽可能不平稳，有弯曲变形的情况，通常出现这种情况是不可行的，山东电缆桥架

金属线槽应该是平整、无扭曲变形，内壁应光滑、无毛刺。

Some metal trough may not smooth, a bending deformation, often appear this kind of circumstance is not feasible, shandong cable tray metal trough should be level off, without distortion, inner surface should be smooth, no burr.
