由于電纜橋架具有品種全、應(yīng)用廣、強度大、結(jié)構(gòu)輕、造價低、施工簡單、配線靈活、安裝標準、外形美觀的特點，給技術(shù)改進、電纜擴充、維護檢修帶來方便，在工程中得到了廣泛的運用，下面濟南電纜橋架廠家來講講玻璃鋼電纜橋架的選用技術(shù)要點。

The cable tray has the characteristics of complete variety, wide application, large strength, light structure, low cost, simple construction, flexible wiring, standard installation, and beautiful appearance, which brings convenience to technical improvement, cable expansion, maintenance and overhaul, and has been widely used in the project. Next, Jinan cable tray manufacturer will talk about the technical key points of selecting GRP cable tray.

1.電纜橋架、線槽及其支吊架使用在有腐蝕性環(huán)境中，應(yīng)采用耐腐蝕的剛性材料制造，或采取防腐蝕處理，防腐蝕處理方式應(yīng)滿足工程環(huán)境和耐久性的要求。

1. The cable tray, trunking and its supports and hangers shall be made of corrosion-resistant rigid materials or treated with anti-corrosion treatment, which shall meet the requirements of engineering environment and durability.

2.電纜橋架在有防火要求的區(qū)段內(nèi)，可在電纜梯架、托盤內(nèi)添加具有耐火或耐燃性能的板、網(wǎng)等材料構(gòu)成封閉或半封閉式結(jié)構(gòu)，并采取在橋架及其支吊架表面涂刷防火涂層等措施，其整體耐火性能應(yīng)滿足有關(guān)規(guī)范或標準的要求。

2. In the section with fire protection requirements, the cable tray can be added with fire-resistant or flame resistant plates, nets and other materials in the cable ladder and tray to form a closed or semi closed structure, and measures such as painting fire-resistant coating on the surface of the tray and its supports and hangers shall be taken. The overall fire resistance shall meet the requirements of relevant national codes or standards.

3.電纜梯架、托盤寬度和高度的選擇應(yīng)符合填充率的要求，電纜的梯架和托盤內(nèi)的填充率在一般情況下，電力電纜可取40%～50％，控制電纜可取50%～70％，且宜預(yù)留10%～25％工程發(fā)展裕量。

3. The selection of width and height of cable ladder and tray shall meet the requirements of filling rate. In general, the filling rate of cable ladder and tray can be 40%~50% for power cable and 50%~70% for control cable, and 10%~25% engineering development allowance should be reserved.

4.在選擇電纜橋架的彎通或引上、引下裝置時，不應(yīng)小于電纜橋架內(nèi)電纜小允許彎曲半徑。

4. When selecting the bending or leading up and down devices of the cable tray, it shall not be less than the small allowable bending radius of the cable in the cable tray.

玻璃鋼電纜管可在露天立柱或支墩上安裝，橋架吊裝時，應(yīng)盡量采用工字鋼立柱兩側(cè)對稱敷設(shè)。可水平、垂直敷設(shè)，可轉(zhuǎn)角、T字型、十字形分支；可調(diào)寬、調(diào)高、變徑。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://m.ymmgjx.net進行咨詢吧！

Glass fiber reinforced plastic cable pipe can be installed on the open column or buttress. When hoisting the bridge, the I-steel column shall be laid symmetrically on both sides as far as possible. It can be laid horizontally and vertically, with corner, T-shaped and cross shaped branches; Adjustable width, height and diameter.
