Should increase the use of non-porous plate or tray on the bottom of the bridge. [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 ladder bridge parts, cables under ladders, trays fill rate within the general how to sell ladder 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 - bridge] at 1KV and below neutral grounding system, grounding neutral grounding powered devices connected to the system. Air-powered equipment is automatically turned off at Villa, the long direction of the metal bridge level cross-sectional area shall not be less than the specified value. 3, along the full length of the bridge lay another ground lines, each (including non-linear segment) should be at least a little bridge a reliable connection with the grounding line. 4, for vibration place, at the junction of the ground portion of the coil should be installed.
