As a supporting project of the distribution project, there is no special standard guidance at present, and the specification procedures of various manufacturers are also lack of versatility. therefore, in the design and selection of Cable tray supplier, according to the type and quantity of cables in various weak current systems, the suitable bridge should be selected reasonably.
1.Orientation: according to the layout plan of the building, combined with the settings of air-conditioning pipes and electrical pipes, it is convenient for maintenance, and the cable tray is dense to determine the best path of the cable tray.
Indoor, as far as possible along the wall, column, beam and floor erection, if the use of integrated pipe corridor erection, should be erected on one side or parallel of the pipe, and consider leading line and branch line to avoid crossing as far as possible, if there is no other pipe rack to borrow, should set up their own (support) column.
2.Calculation of load: calculate the weight per unit length of the main cable tray on the longitudinal plane of the cable tray.
3.Determination of tray width: the type, specification, arm length, pillar length, spacing, tray width and number of layers of cable tray shall be determined according to the number of cable wiring, cable diameter and cable spacing.
4.Determine its installation mode: determine the fixed mode of the bridge according to the installation position of the bridge, choose suspension type, vertical type, sidewall type or mixed type, the general matching supply of connectors and fasteners, and select the corresponding cover plate according to the bridge structure.
5.Draw the horizontal section of the Cable tray supplier bridge, and also draw the spatial section of the list of materials.
6.if used with power cable overhead lines, the power cable and the weak current cable should be placed in the middle, separated by a partition.
7.When the weak current cable is bridged with other low voltage cables, the weak current system with external shielding layer should be strictly implemented to avoid mutual interference.
