　　3. The distance between the top floor bridge and the floor slab shall not be less than 150mm, and the distance between the upper and lower floor bridges shall not be less than 150mm;

　　4、桥架、线槽按砼特殊角度准确放样、加工、安装；|

　　4. Cable trays and trunking should be accurately laid out, processed, and installed at special angles of concrete; |

　　5、直线段钢制电缆桥架长度超过30 米、铝合金或者玻璃钢制电缆桥架长度超过15 米设有伸缩节；电缆桥架跨越建筑物变形缝处设置补偿装置；

　　5. Steel cable trays with a length exceeding 30 meters in straight sections, and aluminum alloy or fiberglass cable trays with a length exceeding 15 meters are equipped with expansion joints; Install compensation devices at the deformation joints where cable trays cross buildings;

　　6、金属电缆桥架及其支架全长应不少于2 处于接地干线相连接；桥架首位两端需与配电柜外壳或地线排可靠连接；

　　6. The total length of metal cable trays and their supports should be no less than 2 connected to the grounding main line; The first two ends of the bridge should be reliably connected to the outer shell of the distribution cabinet or the grounding wire;

　　7、非镀锌电缆桥架间连接板的两端跨接铜芯接地线，跨接地线一定要注意线槽桥架专用接地孔上，地线的小允许截面积不小于4mm2；连接前剔除接地螺栓下方的绝缘层；镀锌桥架连接板的两端不跨接接地线，但连接板两端不少于2 个有防松螺帽或防松垫圈的连接固定螺栓；

　　7. The two ends of the connecting plate between non galvanized cable trays should be bridged with copper core grounding wires. Attention must be paid to the dedicated grounding holes on the cable tray for the grounding wires. The minimum allowable cross-sectional area of the grounding wire should not be less than 4mm2; Remove the insulation layer below the grounding bolt before connection; The two ends of the galvanized bridge connecting plate shall not be connected to the grounding wire, but there shall be no less than 2 connection fixing bolts with anti loosening nuts or anti loosening washers at both ends of the connecting plate;

　　8、与土建配合，桥架穿越墙体、楼板等部位预先留孔；

　　8. Cooperate with civil engineering to leave holes in advance for cable trays passing through walls, floors, and other parts;

　　9、线槽、桥架底板应与支吊架横担用金属螺栓固定（≤200mm,用一个螺栓固定；＞200mm，距边1/4 处两个螺栓固定）；桥架穿越墙体及楼板，应用不燃材料封堵；穿越防火分区桥架内必须做防火封堵；

　　9. The bottom plate of the trunking and bridge should be fixed with metal bolts to the cross arm of the support and hanger (≤ 200mm, fixed with one bolt; ＞200mm， Two bolts are fixed at a distance of 1/4 from the edge; Bridge passing through walls and floors should be sealed with non combustible materials; Fire sealing must be done inside the bridge frame passing through the fire compartment;

　　10、室外安装桥架安装高度不能低于积雪、积水高度，同时考虑选用防水型盖板，进出室外桥架、线槽，室内须高于室外，防止雨水流入室内。

　　10. The installation height of outdoor cable trays should not be lower than the height of snow and accumulated water. At the same time, waterproof cover plates should be considered. For outdoor cable trays and trunking, the indoor height should be higher than the outdoor height to prevent rainwater from flowing into the indoor area.
