[Chai Jin cable tray to recommend the star product - as long as the bridge] modular cable tray with wide 100,150,200mm three groups based on what you need to be able to compose foot cable tray (20) inches of cable tray, it without production elbow, tee and other accessories can be installed according to the site to any steering, widens lead on points, cited under. In any part, no drilling, welding pipe can be elicited. It can facilitate the engineering design, manufacture and convenient transportation, more convenient installation and construction, is currently the best in cable tray products. [Chai Jin cable tray to recommend the star product - Bridge] If the different levels of cable laying in the same cable tray, the middle partition should be increased isolation. 1.8 When the steel line segment length exceeds 30m trough cable tray, cable tray when aluminum exceed 15m. Or when the cable tray after construction should stretch (settlement) seam allowance leaving O-30mm compensation. Its retractable connector plate connection should be used. 1.9 cable ladder, tray width and height should be chosen to meet the requirements of the filling factor, cable ladder, under normal circumstances tray fill rate of cable tray, power cable desirable 40% -50%, 50% preferred the control cables . 70%. L0% and should be reserved for a 252 project development margin. 1.10 In selecting cable tray load rating if the actual span cable tray hanger is not equal to 2m when. The work uniform load should be met: where qG ---- Work uniform load, kN / m; qE ---- rated uniformly distributed load, kN / m; LG ---- actual span, m. Rated bridge uniform load rating in Table 1. [Chai Jin cable tray to recommend the star product - the bridge] due to a variety of pipeline parallel to the cross within the building, space is limited, especially for large office buildings, commercial finance, hotels, stadiums and other buildings, information points intensive tray cable tray, cable In addition to using the floor line trenches and laying pipe way outside the walls, the ceiling in the shaft and the house is widely used cable tray ceiling, to provide different wiring, weak system of classification of the various cables placed in the tray cloth, its best routing and installation according to the requirements of the position and combine architecture and air conditioning, electrical and other pipeline negotiations to be determined, the cable can not be passive and active cable laying side by side, under limited conditions placement within the same bridge, during must be divided metal separators, leads to flat cable to avoid crossing the bridge across the floor, wall or when Cascade cable bridge expansion joints should be marked on the building plans to leave the position of the corresponding holes and avoid missing until construction of temporary air drill, may hurt the civil engineering structures. To prevent electromagnetic radiation interference (EMC), in the design of the bridge should be considered a closed bridge.
