[Chai Jin cable tray to recommend star products - Tray] cable trays are designed to be used to follow a certain formula, introduced under the following specific formula: in design calculations, the actual load capacity if the cable tray with G Total said: then: G Total = n1g1 n2g2 n3g3 ...... Where: g1 g2, g3 ...... are various models within the cable tray weight per unit length. Units (kg / m) n1, n2, n3 is the number of different types and specifications of the cable. [Chai Jin cable tray to recommend the star product - bridge] bridge control cables within its total cross section s does not exceed the total cross section of cable tray s. The 40% principle. The total cross section s control cable is: where: s1, s2, s3 ...... for various control cables within the bridge cross-sectional area (including the sheath portion) unit is mm, d3 ...... within the outer diameter of the cable tray various control galvanized tray standard units of mm; nnn ...... root number is above the same types of specifications of the cable. Corresponding control cable tray width b: where h is the height of the cable tray, the unit is mm. When the cable tray installation in indoor galvanized tray manufacturers, to ensure the bridge straight appearance, neat line, it generally horizontal load deformation should be controlled within 4.0mm.
