Calculate Size of Anchor fastener for Cable Tray Support having following Details

• CABLE TRAY DETAIL: * Size of Cable Tray=600mm Ladder Type Cable Tray * Weight of Cable Tray=120 kg/meter * CABLE DETAILS (LAID IN CABLE TRAY) * Size of Cable =3.5Cx300 Sq.mm, Alu, XLPE, Armored Cable * No of Cable / Cable tray= 6 No’s * Weight of Cable = 5.9 Kg/meter * Size of Cable =3.5Cx150 Sq.mm, Alu, XLPE, Armored Cable * No of Cable / Cable tray= 2 No’s * Weight of Cable = 4.5 Kg/meter. * CABLE TRAY SUPPORT DETAILS * Cable Tray Support installed at 1 Meter of Cable Tray * Weight of Cable Tray Support =5.8 Kg/meter * Safety Factor=5

CALCULATIONS

• Weight of Cable Tray Support = No of Support X Weight of Support * Weight of Cable Tray Support =1×5.8 Kg/Meter * Weight of Cable Tray Support =5.8 Kg/Meter———(A) * Weight of Cable Tray = No of Cable Tray X Weight of Tray * Weight of Cable Tray =1×120 * Weight of Cable Tray =120 Kg/Meter———(B) * Weight of 3.5Cx300 Sq.mm Cable = No of Cable X Weight of Cable * Weight of 3.5Cx300 Sq.mm Cable =6×5.9 * Weight of 3.5Cx300 Sq.mm Cable =35.4 Kg/Meter———(C1) * Weight of 3.5Cx150 Sq.mm Cable = No of Cable X Weight of Cable * Weight of 3.5Cx150 Sq.mm Cable =2×4.5 * Weight of 3.5Cx150 Sq.mm Cable =9 Kg/Meter———(C2) * Total Weight =Safety Factor X (Weight of Cable Tray support + Weight of Cable Tray + Weight of Cables) * Total Weight =5X (5.8+120+35.4+9) Kg/Meter * Total Weight=851 Kg/Meter—————–(1) * Consider 4 No of 10mm size of Anchor Fastener having Basic Tensile Load Capacity of 5KN at each Support. * Total Tensile Load= No of Anchor Fastener X 101.97XAnchor Tensile Load Capacity (KN) * Total Tensile Load=4×101.97×5 * Total Tensile Load=1876 Kg/Meter————(2)

Here Total Tensile Load Capacity of Anchor Fastener (1876 Kg/Meter) > Total Weight (851 Kg/Meter) hence Size of Anchor Fastener is OK
