[Chai Jin cable tray to recommend the star product - the bridge] in the room, as far as possible to set up along the walls, columns, beams and floor of the building, such as Xu take advantage of a comprehensive pipe gallery set up, should be in the side or top of the parallel pipeline erection cable tray and consider deflectors and branch lines to avoid the cross, as no other pipe racks to borrow, you need inception (branch) column. (2) Load Calculation: trunk cable bridge profile weight per unit length of the cable. [Chai Jin cable tray to recommend the star product - bridge 2, such as the power cable tray combination, should power cables and electronic cables between each straight side of the cable tray how to sell, in the middle separated by diaphragms. 3, weak cable in combination with other low-voltage cable bridge, should be strictly enforced select an outer shield weak system of weak cable, to avoid mutual interference. [Chai Jin cable tray to recommend the star product - bridge] If the different levels of cable laid in the same cable tray cable tray installation, intermediate bulkhead should be increased isolation. 1.8 When the steel straight sections longer than 30m, when aluminum cable bridge over 15m. Or when should retractable cable tray after building (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 in the ladder, tray filling rate in general, the power cables desirable 40% -50%, 50% of the control cable is preferable. 70%. L0% and should set aside a 252 project development margin. 1.10 When choosing cable tray load rating if the actual span cable tray hangers is not equal to 2m time. The work uniform loads should be met: where qG ---- work uniform load cable tray, kN / m; qE ---- rated uniform load, kN / m; LG ---- actual span, m . Rated bridge uniform load rating Table 1.
