[Chai Jin cable tray to recommend the star product - bridge] indoors strong galvanized tray, as far as possible along the wall of the building, columns, beams and slabs set up, take advantage of such a comprehensive pipe gallery set up, it should be in the pipeline side or above the parallel bridge erection galvanized grounding and consider deflectors and branch lines to avoid cross galvanized bridge, as no other pipe rack 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 - 1KV and below the bridge] in neutral grounding system grounded neutral grounding powered devices connected to the system. Fitted at moving off the power when loading Xuan, prefect direction of the metal bridge cross-sectional area of ??not less than a predetermined value. 3, along the full length of the bridge lay another grounding lines, each (including non-linear segment) bridge should be at least a little reliable connection and grounding lines. 4, the vibration place, at the junction of the ground portion of the coil should be installed. [Chai Jin cable tray to recommend the star product - its inner tray] bridge control cable does not exceed the total cross section of cable tray s total cross section s. 40% of the principle. The total cross section s control cable is: where: s1, s2, s3 ...... within the various bridge control cable cross-sectional area (including the protective layer portion) units of mm, d3 ...... within the outer diameter of the cable bridge a variety of control The unit is mm; nnn ...... the number of the same types of specifications for the above cable. The corresponding control cable tray width b: where h is the height of galvanized cable tray bridge factory, in mm. When the cable tray installed indoors, in order to ensure the bridge straight appearance, neat line, its deformation is generally horizontal direction load should be controlled within 4.0mm.
