槽式电缆桥架的选用关键

槽式电缆桥架的选用关键
Key to selection of trough cable tray
1.槽式电缆桥架及其支吊架运用在有腐蚀性环境中,应选用耐腐蚀的刚性资料制作,或采纳防腐蚀处理,防腐蚀处理方式应满意工程环境和耐久性的要求。
1. When the trough cable bridge and its support and hanger are used in corrosive environment, the corrosion-resistant rigid data should be selected to make, or anti-corrosion treatment should be adopted. The anti-corrosion treatment method should satisfy 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难燃功能的板、网等资料构成关闭或半关闭式结构,并采纳在桥架及其支吊架表面涂刷防火涂层等办法,其全体耐火功能应满意国家有关规范或规范的要求。
2. In the section where the fire-proof requirement exists, the cable bridge frame can be closed or semi-closed by adding fire-resistant or flame-retardant materials such as plates and nets into the cable ladder and tray, and by coating the surface of the bridge frame and its supporting suspension frame with fire-proof coating, the fire-proof function of the cable bridge frame should be satisfied with the requirements of relevant national codes or codes. Please.
3.在工程防火要求较高的场所,不宜选用铝合金电缆桥架。
3. aluminum alloy cable bridge should not be used in places where fire safety requirements are high.

4.槽式电缆桥架宽度和高度的挑选应契合填充率的要求,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%,操控电缆可取50%~70%,且宜预留10%~25%工程发展裕量。
4. The selection of the width and height of the trough cable bridge should meet the requirements of the filling rate. The filling rate in the cable ladder and tray can be 40%-50% for the power cable, 50%-70% for the control cable, and 10%-25% for the project development margin should be reserved.
5.在挑选电缆桥架的荷载等级时,电缆桥架的作业均布荷载不该大于所选电缆桥架荷载等级的额定均布荷载,假如电缆桥架的支吊架的实践跨距不等于2m时,则作业均布荷载应满意要求。
5. When choosing the load grade of cable bridge, the uniformly distributed load of cable bridge should not be greater than the rated uniformly distributed load of the selected cable bridge load grade. If the practical span of the suspension frame of cable bridge is not equal to 2 m, the uniformly distributed load of the operation should be satisfied.
6.各种组件及支吊架在满意相应荷载的条件下,其规格尺度应与托盘、梯架的直线段、弯通系列相匹配。
6. Under the condition of satisfying the corresponding load, the specifications of various components and hangers should match the straight line segment and bending series of pallets, ladders.
7.在挑选槽式电缆桥架的弯通或引上、引下设备时,不该小于电缆桥架内电缆最小答应曲折半径。8)关于跨距大于6m的钢制电缆桥架和跨距大于2m或承载要求大于荷载等级D级的铝合金电缆桥架,应按工程条件进行强度、刚度及稳定性的计算或试验验证。
7. The minimum allowable bending radius of cables in the cable bridge should not be less than that of the cable in the cable bridge when selecting the bending or leading up and setting down the equipment of the slot cable bridge. 8) The strength, stiffness and stability of steel cable bridges with spans greater than 6 m and aluminum alloy cable bridges with spans greater than 2 m or load-bearing requirements greater than grade D should be calculated or tested according to engineering conditions.
