由于电缆桥架具有品种全、应用广、强度大、结构轻、造价低、施工简单、配线灵活、安装标准、外形美观的特点，给技术改进、电缆扩充、维护检修带来方便，在工程中得到了广泛的运用，下面 济南电缆桥架厂家来讲讲玻璃钢电缆桥架的选用技术要点。

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.电缆桥架、线槽及其支吊架使用在有腐蚀性环境中，应采用耐腐蚀的刚性材料制造，或采取防腐蚀处理，防腐蚀处理方式应满足工程环境和耐久性的要求。

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.电缆桥架在有防火要求的区段内，可在电缆梯架、托盘内添加具有耐火或耐燃性能的板、网等材料构成封闭或半封闭式结构，并采取在桥架及其支吊架表面涂刷防火涂层等措施，其整体耐火性能应满足有关规范或标准的要求。

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.电缆梯架、托盘宽度和高度的选择应符合填充率的要求，电缆的梯架和托盘内的填充率在一般情况下，电力电缆可取40%～50％，控制电缆可取50%～70％，且宜预留10%～25％工程发展裕量。

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.在选择电缆桥架的弯通或引上、引下装置时，不应小于电缆桥架内电缆小允许弯曲半径。

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.

玻璃钢电缆管可在露天立柱或支墩上安装，桥架吊装时，应尽量采用工字钢立柱两侧对称敷设。可水平、垂直敷设，可转角、T字型、十字形分支；可调宽、调高、变径。更多相关内容就来我们网站 //www.comprepyme.com进行咨询吧！

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.
