He applies generally larger diameter cable laying galvanized fire bridge, suitable for high and low voltage power cables. [Chai Jin cable tray to recommend the star product - bridge] (2) ladder to the tray unit resistance values ??in Table 2. Table 2 in units of resistance ladder tray (3) cable channel unit resistance values ??in Table 3 (4) When the cable tray installation and connection process as a whole, the ladder each side (or each cable channel) of resistance: R = L (r + 1 / 3r ') where: R-- ladder side, i.e., (cable trays) Length total resistance (mΩ); r-- ladder side resistance per unit length (mΩ / m) r' - Direct plate bolt contact resistance. [Chai Jin cable tray to recommend the star product - bridge 2, such as when combined with the power cable tray, power cables and electronic cables should each straight side of the fire bridge manufacturers, separated by an intermediate diaphragms. 3, weak cable combined with other low-voltage cable bridge, should be strictly enforced outer shield choose a weak system of weak cable to avoid mutual interference.
