Cable tray price, north bridge election Chai Jin (certified), Xiqing cable tray cable tray provided by the Tianjin Chai Jin Limited. Chai Jin Tianjin cable bridge Limited (www.tjcjdlqj.com) is specialized in "galvanized bridge, fire bridge, ladder tray, spray tray, FRP bridge, galvanized bridge" of the enterprise, the company adhering to the "integrity management, intentions of service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Cai Yu Guan. [Chai Jin cable tray to recommend the star product - bridge] install cable tray installation, refer to the standard issued by China Architecture Design & Research JSJT-121 National General Building Standard Design - Electrical equipment standards Atlas "cable tray installation" 04D701 -3. Eight, design requirements 1, the bridge system path floorplan; 2, a cross sectional view about the bridge system. 3, corrosion-resistant materials used in the system tray and the required straight, curved bill pass, branch (hanging) the size and number of racks and the necessary instructions Cascade cable bridge, connecting plate and screws, according to the above requirements for protective cap fitted by the manufacturer Qi. 4, there is a non-standard technical description or illustration special requirements. 5, to a limited extent in the budget trough cable tray design required to meet safety requirements. [Chai Jin cable tray to recommend the star product - the carrying capacity of the bridge] is usually cable tray cable tray load characteristic curve represents. As can be seen from the graph of load size fireproof cable tray, cable tray loading capacity is the amount of a bridge away from the relevant specifications and support. The same distance between the support and the amount of deformation corresponding to the convex bending. Side height of the bridge carrying capacity, the height of a small bridge carrying capacity is small. In addition, when the load capacity planning, is the same, for the same cable tray specifications. Small distance from the support than the support of a large amount of bending deformation is small. Under normal circumstances every l.5 ~ 2.0m cable tray installation of a set of brace.
