電纜橋架的十二條布線規矩:在室內選用電纜橋架布線時,其電纜不該有黃麻或其他易延燃資料外護層。電纜橋架水平裝置時,宜按荷載曲線選取最佳跨距進行支撐,跨距一般為1.5~3m.筆直敷設時,其固定點間隔不宜大于2m。在有腐蝕或特別濕潤的場所選用電纜橋架布線時,應根據腐蝕介質的不同采納相應的防護辦法,并宜選用塑料護套電纜。幾組電纜橋架在同一高度平行裝置時,各相鄰電纜橋架間應考慮維護、檢修間隔。
Twelve wiring rules for cable tray: when selecting cable tray for indoor wiring, the cable shall not have jute or other combustible material outer sheath. When the cable tray is installed horizontally, the best span should be selected for support according to the load curve, and the span is generally 1.5 ~ 3M When laying straight, the interval between fixed points shall not be greater than 2m. When cable tray wiring is selected in places with corrosion or special humidity, corresponding protection methods shall be adopted according to different corrosive media, and plastic sheathed cables shall be selected. When several groups of cable trays are installed in parallel at the same height, maintenance and overhaul intervals shall be considered between adjacent cable trays.
在電纜橋架上能夠無間隔敷設電纜,電纜在橋架內橫斷面的填充率:電力電纜不該大于40%;操控電纜不該大于50%.電纜橋架水平裝置時的距地高度一般不宜低于2.50m,筆直裝置時距地1.80m以下部分應加金屬蓋板維護,但敷設在電氣專用房間內時在外。電纜橋架不宜裝置在腐蝕性氣體管道和熱力管道的上方及腐蝕性液體管道的下方,否則應采納防腐、隔熱辦法。)同一路徑向一級負荷供電的雙路電源電纜,強電和弱電電纜。如受條件約束需安裝在同一層橋架上時,使用隔板離隔。
The cable can be laid on the cable tray without interval. The filling rate of the cross section of the cable in the cable tray: the power cable shall not be greater than 40%; The control cable shall not be greater than 50% Generally, the height of the cable tray from the ground when it is installed horizontally shall not be less than 2.50M. When it is installed vertically, the part below 1.80m from the ground shall be maintained with a metal cover plate, but when it is laid in the special electrical room, it shall be outside. The cable tray shall not be installed above the corrosive gas pipeline and heat pipeline and below the corrosive liquid pipeline, otherwise anti-corrosion and heat insulation measures shall be adopted.) Dual power cables, strong current and weak current cables that supply power to class I load in the same path. If it is constrained by conditions and needs to be installed on the bridge on the same floor, the partition plate shall be used for separation.
1. 電纜橋架布線適用于電纜數量較多或較集中的場所。
1. Cable tray wiring is applicable to places with large or concentrated cables.
2. 在有腐蝕或特別潮濕的場所采用電纜橋架布線時,應根據腐蝕介質的不同采取相應的防護措施,并宜選用塑料護套電纜。
2. When cable tray wiring is used in places with corrosion or special humidity, corresponding protective measures shall be taken according to different corrosive media, and plastic sheathed cables should be selected.
3. 電纜橋架水平敷設時的距地高度不宜低于2.5m,垂直敷設時距地高度不宜低于1.8m。除敷設在電氣專用房間內外,當不能滿足要求時,應加金屬蓋板保護。

3. When the cable tray is laid horizontally, the height from the ground shall not be less than 2.5m, and when it is laid vertically, the height from the ground shall not be less than 1.8m. In addition to laying inside and outside the special electrical room, when the requirements cannot be met, metal cover plate shall be added for protection.
4. 電纜橋架水平敷設時,宜按荷載曲線選取最佳跨距進行支撐,跨距宜為1.5~3m。垂直敷設時,其固定點間距不宜大于2m。
4. When the cable tray is laid horizontally, the best span should be selected for support according to the load curve, and the span should be 1.5 ~ 3M. When laying vertically, the distance between fixed points shall not be greater than 2m.
5. 電纜橋架多層敷設時,其層間距離應符合下列規定:
5. When the cable tray is laid in multiple layers, the distance between layers shall comply with the following provisions:
1)電力電纜橋架間不應小于0.3m;
1) The distance between power cable trays shall not be less than 0.3m;
2)電信電纜與電力電纜橋架間不宜小于0.5m,當有屏蔽蓋板時可減少到0.3m;
2) The distance between telecommunication cable and power cable bridge shall not be less than 0.5m. When there is a shielding cover plate, it can be reduced to 0.3m;
3)控制電纜橋架間不應小于0.2m;
3) The distance between control cable trays shall not be less than 0.2m;
4)橋架上部距頂棚、樓板或梁等障礙物不宜小于0.3m。
4) The distance from the upper part of the bridge to the ceiling, floor or beam and other obstacles shall not be less than 0.3m.
6. 當兩組或兩組以上電纜橋架在同一高度平行或上下平行敷設時,各相鄰電纜橋架間應預留維護、檢修距離。
6. When two or more groups of cable trays are laid in parallel at the same height or up and down, a maintenance and overhaul distance shall be reserved between adjacent cable trays.
7. 在電纜托盤上可無問距敷設電纜。電纜總截面積與托盤內橫斷面積的比值,電力電纜不應大于40%;控制電纜不應大于50%。
7. Cables can be laid on the cable tray without distance. The ratio of the total cross-sectional area of the cable to the cross-sectional area in the tray shall not be greater than 40% for power cables; The control cable shall not be greater than 50%.
