　　·The total length of the metal bridge should be connected to the grounding (PE) or neutral (PEN) main line at no less than 2 points, and the starting and ending ends must be connected to the building grounding device.

　　· 非鍍鋅橋架連接板兩端必須用≥4mm銅芯線跨接，鍍鋅橋架連接板兩端可不做跨接接地線，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。

　　·Non galvanized bridge connecting plates must be bridged with ≥ 4mm copper core wires at both ends. Galvanized bridge connecting plates do not need to have bridging grounding wires at both ends, but there must be at least 2 connection fixing bolts with anti loosening nuts or washers at both ends of the connecting plate.

　　4.伸縮節(jié)與補償裝置

　　4. Expansion joint and compensation device

　　· 直線段鋼制電纜橋架超過30m、鋁合金或玻璃鋼制電纜橋架超過15m時，應設置伸縮節(jié)，伸縮縫不小于20mm。

　　·When the straight section steel cable tray exceeds 30m, and the aluminum alloy or fiberglass cable tray exceeds 15m, expansion joints should be installed, with expansion joints not less than 20mm.

　　· 橋架跨越建筑物變形縫處應設置補償裝置。

　　·Compensation devices should be installed at the deformation joints where the bridge spans the building.

　　5.電纜敷設

　　5. Cable laying

　　· 電纜在橋架內(nèi)的填充率，動力電纜不應大于40%，控制電纜不應大于50%。

　　·The filling rate of cables in the cable tray should not exceed 40% for power cables and 50% for control cables.

　　· 電纜小彎曲半徑應符合規(guī)定，無絞擰、鎧裝壓扁、護層斷裂等缺陷。

　　·The minimum bending radius of the cable should comply with regulations, and there should be no defects such as twisting, armor flattening, or protective layer breakage.

　　· 電纜固定應符合要求，水平敷設時，在電纜首末端、轉(zhuǎn)彎處及每隔3-5m固定；垂直敷設時，在電纜上端和每隔1.5m固定。

　　·The cable fixation should meet the requirements. When laying horizontally, it should be fixed at the beginning and end of the cable, at the turning point, and every 3-5m; When laying vertically, fix it at the top of the cable and every 1.5m.

　　6.防火與防護

　　6. Fire prevention and protection

　　· 橋架穿越防火墻、樓板時，應采取防火封堵措施，封堵材料應符合防火要求。

　　·When the bridge passes through firewalls and floor slabs, fireproof sealing measures should be taken, and the sealing materials should meet the fire prevention requirements.

　　· 戶外橋架應有排水孔，坡度≥3‰，防止積水；腐蝕環(huán)境應采用防腐型橋架。

　　·Outdoor cable trays should have drainage holes with a slope of ≥ 3 ‰ to prevent water accumulation; Corrosive environments should use anti-corrosion cable trays.

　　7.外觀與防腐

　　7. Appearance and anti-corrosion

　　· 橋架表面應無變形、劃傷、開裂，內(nèi)側(cè)應平整光滑，無損傷電纜絕緣的凸起尖角。

　　·The surface of the cable tray should be free of deformation, scratches, and cracks, and the inner side should be flat and smooth, without protruding corners that damage the cable insulation.
