　　4、橋架、線槽按砼特殊角度準確放樣、加工、安裝；|

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

　　5、直線段鋼制電纜橋架長度超過30 米、鋁合金或者玻璃鋼制電纜橋架長度超過15 米設有伸縮節；電纜橋架跨越建筑物變形縫處設置補償裝置；

　　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、金屬電纜橋架及其支架全長應不少于2 處于接地干線相連接；橋架首位兩端需與配電柜外殼或地線排可靠連接；

　　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、非鍍鋅電纜橋架間連接板的兩端跨接銅芯接地線，跨接地線一定要注意線槽橋架專用接地孔上，地線的小允許截面積不小于4mm2；連接前剔除接地螺栓下方的絕緣層；鍍鋅橋架連接板的兩端不跨接接地線，但連接板兩端不少于2 個有防松螺帽或防松墊圈的連接固定螺栓；

　　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、與土建配合，橋架穿越墻體、樓板等部位預先留孔；

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

　　9、線槽、橋架底板應與支吊架橫擔用金屬螺栓固定（≤200mm,用一個螺栓固定；＞200mm，距邊1/4 處兩個螺栓固定）；橋架穿越墻體及樓板，應用不燃材料封堵；穿越防火分區橋架內必須做防火封堵；

　　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、室外安裝橋架安裝高度不能低于積雪、積水高度，同時考慮選用防水型蓋板，進出室外橋架、線槽，室內須高于室外，防止雨水流入室內。

　　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.
