Brackets and brackets should also be made of the same materials to improve the service life of cable trays and accessories. Cover plates should be added in environments or outdoor areas that are prone to dust accumulation and require covering.

3、除上述情況外，可根據(jù)現(xiàn)場(chǎng)環(huán)境及技術(shù)要求選用托盤式、槽式、梯級(jí)式、玻璃防腐阻燃電纜橋架或鋼質(zhì)普通型橋架。在容易積灰和其它需遮蓋的環(huán)境或戶外場(chǎng)所宜加蓋板。

3. In addition to the above situations, tray type, trough type, stepped type, glass anti-corrosion flame-retardant cable tray or steel ordinary type tray can be selected according to the on-site environment and technical requirements. Cover plates should be added in environments or outdoor areas that are prone to dust accumulation and require covering.

4、在公共通道或戶外跨越道路段，底層梯級(jí)的底部宜加墊板或在該段使用托盤。大跨距跨越公共通道時(shí)，可根據(jù)用戶要求提高橋架的載荷能力或選用行架。

4. In public passages or outdoor crossing road sections, it is advisable to add a pad at the bottom of the bottom step or use a pallet at that section. When crossing a public passage with a large span, the load capacity of the bridge can be increased or a gantry can be selected according to user requirements.

5、大跨距(>3m)要選用復(fù)合型橋架(FB)。

5. Composite cable trays (FB) should be used for large spans (>3m).

6、戶外要選用復(fù)合環(huán)氧樹(shù)指橋架(F)。

6. Composite epoxy tree finger bridge (F) should be selected for outdoor use.

電纜橋架廠家直銷規(guī)格選擇

Selection of direct sales specifications for cable tray manufacturers

1、復(fù)合環(huán)氧樹(shù)脂電纜橋架的寬度和高度就按下表選擇，并應(yīng)符合電纜真充率不超過(guò)有關(guān)標(biāo)準(zhǔn)規(guī)范的規(guī)定值，動(dòng)力電纜可取40-50，控制電纜可取50-70，另外需予留10-25的式程發(fā)展余量。

1. The width and height of the composite epoxy resin cable tray should be selected according to the following table, and should comply with the cable true filling rate not exceeding the specified values of relevant standards and specifications. Power cables can be taken as 40-50, control cables can be taken as 50-70, and a process development margin of 10-25 should be left.

2、各種彎通及附件規(guī)格應(yīng)符合工程布置條件并與橋架相配套。

2. The specifications of various bends and accessories should comply with the engineering layout conditions and be matched with the bridge.

3、支、吊架規(guī)格的選擇，應(yīng)按橋架規(guī)格、層數(shù)、跨距等條件配置。并應(yīng)滿足荷載的要求。

3. The selection of support and hanger specifications should be based on conditions such as cable tray specifications, number of layers, and span. And it should meet the requirements of the load.

對(duì)于電纜橋架的支、吊架的配置

Configuration of supports and hangers for cable trays

1、戶內(nèi)支、吊短跨距一般采取1.5-3m;戶外立柱中跨距一般采取6m。

1. The short span of indoor support and suspension is generally 1.5-3m; The span of outdoor columns is generally 6 meters.

2、非直線段的支、吊架配置就遵循以下原則：當(dāng)橋架寬度<300mm時(shí)，應(yīng)在距非直線段與直線結(jié)合處300-600m的直線段側(cè)設(shè)置一個(gè)支、吊架;當(dāng)橋架寬度>300mm時(shí)，除符合下述條件外，在非直線段中部還應(yīng)增設(shè)一個(gè)支、吊架。

2. The configuration of supports and hangers for non linear sections follows the following principles: when the bridge width is less than 300mm, a support or hanger should be set on the side of the straight section 300-600m away from the junction of the non linear section and the straight line; When the width of the bridge is greater than 300mm, in addition to meeting the following conditions, a support and hanger should also be added in the middle of the non linear section.

3、拉擠玻璃鋼電纜橋架多層設(shè)置時(shí)層間中間距為200，250，300，350mm。

3. When the pultruded fiberglass cable tray is set in multiple layers, the interlayer spacing is 200250300350mm.

4、橋架直線段每隔50m應(yīng)予留伸縮縫20-30mm(金屬橋架)。

4. Expansion joints of 20-30mm (metal bridge) should be left every 50m in the straight section of the bridge.
