[Chai Jin cable tray to recommend the star product - bridge] trough cable tray trough cable tray is a fully enclosed cable tray. It is applicable for laying computer cables, communication cables, thermocouple cables and other sensitive systems control cables. It controls shielded cable interference and heavy corrosion in the cable environment protection have good results. Stepped, tray, trough cable tray respective advantages and disadvantages: stepped line bridge with good ventilation performance FRP cable tray, no dust, no interference. Trough, tray-line bridge with dust, anti-interference performance. [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 cable tray prices, aluminum cable tray exceeds 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 filling ratio of FRP bridge, power cables 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] in easy to fouling and the need to cover the environment or other outdoor venues should be stamped plate. 3, in addition to the above, according to the site can also choose the environment and technical requirements tray, trough, stepped glass or steel corrosion retardant cable tray common type bridge. In easy to fouling and the need to cover the environment or other outdoor venues should be stamped plate. 4, or outdoors in public access across the road segment, the bottom rung of the bottom plate or tray should be added in the segment. When large span across public channels, can improve the load carrying capacity of the bridge or use walking frames according to user requirements. 5, large span (> 3m) to choose composite bridge (FB). 6, to choose outdoor epoxy composite bridge (F). FRP cable tray, Tianjin Chai Jin bridge (certified), provided by the Tianjin Chai Jin Langfang bridge cable bridge Limited.
