[Chai Jin cable tray to recommend the star product - bridge] 1, Cascade cable bridge CQ1-T based Cascade cable bridge is based on the information at home and abroad to improve the design. It is light weight, low cost, unique, easy installation, cooling, ventilation and good. He applied to the larger diameter cable laying ships, suitable for high and low voltage power cables. [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, Xingtai fire bridge, d3 ...... for a variety of control within the bridge the outer diameter of the cable, fire bridge how, in units of mm; nnn ...... the number of the same kinds of the above model specifications of the cable. The corresponding control cable tray width b: where h is the height of the cable tray, the unit is 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. [Chai Jin cable tray to recommend the star product - bridge] 5, material statistics (1) bridge: statistics of the total length of the bridge various models, in addition to the standard length of a bridge, obtained the number of trays outside, an additional 1% -2% of the balance. (2) Column: As unified specifications of the column, available divided by the average total length of the bridge column spacing, column number drawn, fire bridge the price, an additional 2% to 4% margin. A post different specifications, we need statistics separately. (3) the holding arm: bridge full-length divided by the average spacing bracket arm, and then add 1% to 2% margin, extremely total demand. (4) Other components: its body multiplied by a certain percentage (depending on the plant may be) to obtain the total number.
