[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 galvanized bridge, i.e. (cable trays) Length total resistance (mΩ); r-- ladder side resistance per unit length (mΩ / m) r' - Direct contact resistance plate bolts. [Chai Jin cable tray to recommend the star product - the bridge] deformation under load size selected cable tray width and the desired horizontal tray, check the corresponding structure in the form of bridge load curve galvanized tray price, when not meet the deformation requirements, can be appropriately increased or reduced high-side tray support spacing, in order to meet the requirements. Cable tray is stamped with a thin steel plate. Its carrying capacity has a certain limit. Otherwise it will cause serious overloading bridge deformation. Affect the safe operation of the bridge's beauty and cables. Strong galvanized tray Texas _ _ galvanized tray provided by Tianjin Tianjin bridge election Chai Jin Chai Jin cable bridge Limited.
