[Chai Jin cable tray to recommend the star product - the bridge] in the selection, cable tray type cable support, manufacturing plant to provide the allowable load capacity should be greater than the actual amount of load G total. When the cable tray with cover in outdoor installations, cable trays should be counted withstand the maximum load of snow and other effects. Cable tray width b determination with the different power cables and control cables duty rather different. As the power cable in the bridge are generally single-level emissions, so the installation of the bridge width b is: b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ...... Where: d1 , d2, a variety of cable outer diameter of the inner tray d3 ...... is, Baoding cable tray, the unit is mmn1, n2, n3 ...... the number of the same kinds of the above-mentioned model specification cable. K1, k2, k3 ...... spacing when said cable is placed. The value should be greater than 1/4 of the minimum diameter of the cable. In general, the control cable may be arranged both horizontally in the tray to be stacked. [Chai Jin cable tray to recommend the star product - bridge] install cable tray installation, refer to the standards issued by the China Architecture Design & Research JSJT-121 National General Building Standard Design - Electrical equipment standards Atlas "cable tray installation" 04D701 -3. Eight, the design requirements 1, the bridge system path floorplan; 2, about the cross-sectional view of the bridge system. 3, the bridge system uses corrosion-resistant materials and the necessary pass-through, schedules elbow, branch (hanging) the size and number of racks and the necessary instructions, cable bridge specifications, connecting plate and screws, headgear according to the manufacturer with the above requirements Qi. 4, non-standard technical instructions or diagrams special requirements. 5, within the scope of a limited budget, the design needs to meet the safety requirements. [Chai Jin cable tray to recommend the star product - the carrying capacity of the bridge] is the usual cable bridge cable bridge with a load characteristic curve represents. As can be seen by the load curves, the size of the cable tray loading capacity is the amount of a bridge and the support from the relevant specifications. The same support and curved projection distance corresponding to the amount of deformation. Side height of the bridge carrying capacity, the height of a small bridge carrying capacity is small. In addition, when the load capacity program, the same, for the same specification of cable tray. Support from the small distance is greater than the support of a small amount of bending deformation. Under normal circumstances the cable tray every l.5 ~ 2.0m Install a support frame.
