[Chai Jin cable tray to recommend the star product - Bridge] company to provide accurate and timely services trough bridge 200100, high-quality galvanized trough bridge products, competitive prices, we will now look to the future, and constantly open innovation, advance with the times. Some are passive electrical (optical) cable (such as data cables, video coaxial cable, etc.), so that when the arrangement layout and routing in the design, should be distinguished, should not only meet the specification requirements, but also consider wiring security, scalability, economy and aesthetics, ease of maintenance, cable tray as the bearer of various cabling carrier belonging wiring needs trough bridge, the same should be implemented following the above principles. [Chai Jin cable tray to recommend the star product -] tray tray tray cable bridge in the selection of cable tray in the general level of emissions is a single layer, so its installation bridge width b is: b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ...... n1, n2, n3 ...... isoform above the number of model specifications of the cable. [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, while aluminum cable bridge over 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, the width and height of the tray should be chosen to meet the requirements of the filling factor, in cable ladder, tray fill rate in general, the power cable preferably 40% -50%, preferably 50% of the control cable. 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 ---- working fire trough bridge uniform load, kN / m; qE ---- rated uniformly distributed load, kN / m; LG ---- actual span , m. Rated bridge uniform load rating in Table 1. Trough bridge specifications Chai Jin Bridge Works _ _ Tianjin Wuqing bridge trough cable tray provided by the Tianjin Chai Jin Limited.
