[Chai Jin cable tray to recommend the star product - the bridge] intelligent building weak systems offer fire bridge, there are usually multiple information monitoring and communication facilities such as BA (Building Automation), OA (Office Automation), CA (Communication Automation) and other system components corresponding to BA fire bridge, for example, in addition to building their own power supply, water supply and drainage, air conditioning, elevators and parking facilities configuration information necessary to monitor, there are SA (Security Automation), FA (Fire automation ) several sub-systems such as fire bridge installation, system integration or part of the system integration. [Chai Jin cable tray to recommend the star product - the bridge] deformation under load size selected cable tray width and the desired horizontal tray, check the corresponding structure in the form of bridge load curve, when you can not meet the requirements of the deformation spraying fire bridge, can be appropriate to increase or decrease the high side of the bridge support spacing in order to meet the requirements. Cable tray is stamped with a thin steel plate. Its carrying capacity has a certain limit. Otherwise it will cause serious overloading bridge deformation. Affect the safe operation of the bridge's beauty and cables.
