[Chai Jin cable tray to recommend the star product - Bridge] How to get a given deflection deflection trough cable tray, also there is no clearly defined tray cable bridge, apparently in the area should be considered to reduce the burden around degrees, which means The amount of steel will increase accordingly, so long as the full use of the calculation of the maximum allowable stress of steel, and to ensure adequate safety factor, the maximum deflection of the general and span (anchor pitch) than taking a / 250 ~ 1/150 for appropriate. Expansion and contraction problems. [Chai Jin cable tray to recommend the star product - a bridge], supporting the project as a cable tray wiring works, there is no specific regulatory guidance, a manufacturer specifications program lacks versatility, so Cascade cable bridge design Selection process should seem the type, quantity of each system according to the weak cable, select the applicable reasonable bridge. (1) determine the direction: According to the building floor plan, combined with air-conditioning lines and electrical lines and other settings, easy maintenance, as well as cable routing density to determine the best route cable tray. FRP cable tray, tray-known manufacturers Chai Jin (certified), provided by the Tianjin Hangu Chai Jin cable tray cable tray Limited. Chai Jin Tianjin cable bridge Limited (www.tjcjdlqj.com) is Tianjin, metal building materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chai Jin leader in cable tray with the staff warmly welcome all inquiries negotiations to create Chai Jin cable tray a better future.
