[Chai Jin cable tray to recommend the star product - large span cable bridge] current bridge is typically assembled by the FRP profiles, suitable for power cables, control cables, lighting cables and accessories. Compared with the iron bridge, has a long life (typically the design life of twenty years), ease of installation and low cost (specific gravity is only 1/4 of steel, corrosion-resistant cable bridge, construction without flare, single bridge lengths up to 8 meters, cable bridge models, or even longer), cutting easy, no maintenance and other advantages. [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 straight, elbow, schedules branch (hanging) the size and number of racks and the necessary instructions, connecting plate and screws, headgear according to the above requirements fully serviced by the manufacturer. 4, non-standard technical instructions or diagrams special requirements. 5, within the scope of a limited budget, cable tray spot, design need to meet safety requirements. [Chai Jin cable tray to recommend the star product - the bridge]. (2) Installation position horizontal cable tray bridge laying, Weinan cable tray, height from the ground is generally not less than 2.5m. When the bridge multi-laying, for cooling, maintenance and anti-interference between the needs of the bridge layer should leave a certain distance cable tray laid in parallel with the variety of channels, the spacing should be consistent with the relevant provisions. (3) the quality of hangers hanger cable tray installation shall comply with the technical standards at the current level of laying cable trays, support span is usually 1.5 ~ 3m a try when laid vertically, fixed spacing of not more than 2m two-phase level bridge between adjacent carriage arm height difference should not be greater than 10mm, two adjacent vertical deviation bridge corbel vertical centerline should not exceed 20mm.
