采用膨胀螺栓固定电缆桥架的好处
1. cable tray laying level, supporting the distance should be 1 / 4 span bridge between the distance within the joint, it is better for large span bridge put butt on the supporting frame, to increase support in a separate curved way or three way place, perpendicular to the direction of the arm every 1.5m with a fixed point.
2.电缆桥架的大载荷、支撑间距应小于允许载荷和支撑跨距。
2. the maximum load and supporting space of the cable tray shall be less than the allowable load and span.
3.桥架内的电缆应用电缆卡带、或金属电缆卡子进行分组固定。对于水平敷设的电缆通常每隔2m左 右作一固定点;对于垂直敷设的电缆应每隔1—1.5m固定一次，在改变标高的端部也应予以固定。
The application of cable cable, cable clip or metal cassette tray fixed group 3. For horizontally laid cables, a fixed point is usually maintained at intervals of about 2m; for vertically laid cables, shall be fixed once every 1 to 1.5m, and shall be fixed at the end of the change elevation.
4.桥架的安装应以规范为准，桥架在安装过 程中严禁载人。
4. the installation of the bridge shall be subject to the state standards, and the bridge shall be manned strictly during the installation.
5.电缆桥架按电力施工规范要求应进行良好接地，对于镀锌电缆桥架无须有专门接地装置，其本体 即可作为接地干线;对于表面进行非金属处理的桥架则必须有专门的接地装置.
5. cable tray should be well grounded in the electric power construction specification for galvanized cable tray without special grounding device, the body can be used as a grounding line; for surface treatment of non metal bridge must have special grounding device.
6.桥架的立柱、托臂等支架可与基础预埋件焊接固定，也可采用膨胀螺栓固定，对于现场焊接处一 定要做好防腐处理，通常由用户现场涂刷防腐漆。
The 6. column, frame bridge can be fixed and welded based embedded parts, also can use the expansion bolt, for on-site welding must be good anti-corrosion treatment, usually by the user site brushing anticorrosive paint.
桥架的接地线可用VV- 16mm2电缆或等截面的铜编织线，该线通常由用户自备，如由本厂供货，则应在合同中注明，长距离的电缆桥架每隔30—50m接地一次。
The bridge ground available VV- 16mm2 cable or non copper braided wire, the line is owned by the user, such as by the factory delivery, shall be specified in the contract, the long distance cable tray every 30 50m grounding once.
