[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, tray width and height should be chosen to meet the requirements of the filling factor of the cable under the ladder, filling ratio generally within the tray, power cable desirable 40% -50% of cable tray, control cables desirable 50% . 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 cable tray standard, m. Rated bridge uniform load rating in Table 1. [Chai Jin cable tray to recommend the star product - the bridge] in selecting a tray type cable tray, cable tray manufacturing plant is provided to allow the load should be greater than the actual amount of the total amount of load G. When the cable tray with cover in outdoor installations, cable trays should be counted, etc. The maximum snow load impact. Cable tray width b is determined with the different power cables and control cables work system rather different. As the power cables in the bridge are generally single-level emissions, so the installation of the bridge width b is: b = n1 (d1 + k1) + n2 (d2 + k2) + n3 (d3 + k3) + ...... Where: d1 , d2, d3 ...... for a variety of cable outer diameter of the inner tray trough cable tray, the unit is mmn1, n2, n3 ...... above the number of the same types of specifications of the cable. K1, k2, k3 ...... pitch of said cable when placed. The value should be greater than 1/4 of the minimum diameter of the cable. In general, control cables can be arranged either horizontally within the bridge can also be stacked.
