How to carry out cable bridge wiring? We need to know what is the FRP cable bridge, which is assembled by extruded FRP profiles. It is suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, the FRP cable bridge has the advantages of long service life (common design life is 20 years), convenient installation and low cost (the proportion is only 1/4 of carbon steel, no fire is needed in construction, the length of a single bridge can reach 6 meters or even longer), convenient cutting, no maintenance and other advantages, high strength and insulation performance. Good, chemical corrosion resistance and other advantages.

　　假如我們是在復(fù)合環(huán)氧樹脂電纜橋架布線時，其電纜不應(yīng)有黃麻或其他易延燃資料外護層。在有腐蝕或特別濕潤的場所采用電纜橋架布線時，應(yīng)依據(jù)腐蝕介質(zhì)的不同采取相應(yīng)的防護措施，并宜選用塑料護套電纜。電纜橋架（托盤）程度裝置時的距地高度普通不宜低于2．50m，垂直裝置時距地1．80m以下局部應(yīng)加金屬蓋板維護，但敷設(shè)在電氣專用房間（如配電室，電氣豎井、技術(shù)層等）內(nèi)時除外。電纜橋架程度裝置時，宜按荷載曲線選取佳跨距進行支撐，跨距普通為1．5～3m。垂直敷設(shè)時，其固定點間距不宜大于2m。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(yīng)思索維護、檢修間隔。在電纜橋架上能夠無間距敷設(shè)電纜，電纜在橋架內(nèi)橫斷面的填充率：電力電纜不應(yīng)大于40％；控制電纜不應(yīng)大于50％。下列不同電壓，不同用處的電纜，不宜敷設(shè)在同一層橋架上：lkV以上和1kV以下的電纜。同一途徑向一級負荷供電的雙路電源電纜。應(yīng)急照明和其他照明的電纜。強電和弱電電纜。如受條件限制需裝置在同一層橋架上時，應(yīng)用隔板隔開。

　　If we use composite epoxy resin cable bridge in the indoor, the cable should not have jute or other flammable material outer protective layer. When cables are used in corrosive or especially wet places, corresponding protective measures should be taken according to different corrosive media, and plastic sheathed cables should be selected. The distance between cable tray and ground should not be less than 2.50m, while the distance between vertical device and ground should be less than 1.80m. The metal cover should be maintained, except when it is laid in special electrical rooms (such as distribution room, electric shaft, technical layer, etc.). When installing the degree of cable bridge, the optimum span should be selected according to the load curve, and the span is usually 1.5-3 M. When laying vertically, the distance between fixed points should not be more than 2m. When several groups of cable bridges are installed in parallel at the same height, the maintenance and repair intervals between adjacent cable bridges should be considered. Cables can be laid on the cable bridge without spacing. The filling rate of the cross section of the cable in the bridge frame should not be greater than 40% for power cables and 50% for control cables. The following cables with different voltages and different uses should not be laid on the same bridge deck: cables above lkV and below 1kV. Two-way power supply cables that supply power to primary load in the same way. Cables for emergency lighting and other lighting. Strong and weak electric cables. If conditions restrict the installation on the same deck of bridge, the partition shall be applied.

　　電纜橋架與各種管道平行或穿插時，其小凈距應(yīng)契合表DQ4-1的規(guī)則。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(yīng)采取防腐、隔熱措施。電纜橋架內(nèi)的電纜應(yīng)在下列部位進行固定。垂直敷設(shè)時，電纜的上端及每隔1．50～2m處。程度敷設(shè)時，電纜的首、尾兩端、轉(zhuǎn)彎及每隔5～10m處。 電纜橋架與各種管道的小凈距 表DQ4-1管道類別平行凈距(m)穿插凈距（m）普通工藝管道 0.40.3 具有腐蝕性液體（或氣體）管道0.50.5 熱力管道有保溫層 0.50.5 無保溫層1.01.0電纜橋架內(nèi)的電纜應(yīng)在首端、尾端、轉(zhuǎn)彎及每隔50m處，沒有編號、型號及起、止點等標志。電纜橋架在穿過防火墻及防火樓板時，應(yīng)采取防火隔離措施。

　　When a cable bridge is parallel to or intersected with various pipelines, its minimum net distance shall conform to the rules of Table DQ4-1. Cable bridge should not be installed above corrosive gas pipeline and thermal pipeline and below corrosive liquid pipeline. Otherwise, anti-corrosion and heat insulation measures should be taken. The cables in the cable bridge shall be fixed at the following parts. When the cable is laid vertically, the upper end of the cable and every 1.50-2 m place. When the cable is laid to a certain extent, the first and last ends, turning and every 5-10 m of the cable are arranged. Minimum Clean Distance Table DQ4-1 Pipeline Class Parallel Clean Distance (m) Interlacing Clean Distance (m) General Process Pipeline 0.40.3 Corrosive Liquid (or Gas) Pipeline 0.50.5 Thermal Pipeline 0.50.5 Thermal Pipeline with insulation layer 0.50.5 without insulation layer 1.01.0 Cable in cable bridge should be at the head, tail end, turning and every 50 m, No. There are numbers, models, starting and ending points and other signs. Fire-proof isolation measures should be taken when cable bridge traverses firewalls and fire-proof floors.
