Calculation of Cable Tray Size
Calculate Size of Cable Tray for Following Cable Schedule. Cable Tray should be perforated and 20% spare Capacity. Distance between each Cable is 10mm. Cable are laying in Single Layer in Cable Tray. (1) 2 No’s of 3.5Cx300 Sq.mm XLPE Cable having 59.7mm Outer Diameter and 5.9 Kg/Meter weight (2) 2 No’s of 3.5Cx400 Sq.mm XLPE Cable having 68.6mm Outer Diameter and 6.1 Kg/Meter weight (3) 3 No’s of 3.5Cx25 Sq.mm XLPE Cable having 25mm Outer Diameter and 0.5 Kg/Meter weight Calculation: Total Outer Diameter of all Cable Passing in to Cable Tray: Diameter of 300Sq.mm Cable =No of Cable X Outer Diameter of Each Cable Diameter of 300Sq.mm Cable =2X59.7 = 119.4 mm Diameter of 400Sq.mm Cable =No of Cable X Outer Diameter of Each Cable Diameter of 400Sq.mm Cable =2X68.6= 137.2 mm Diameter of 25Sq.mm Cable =No of Cable X Outer Diameter of Each Cable Diameter of 25Sq.mm Cable =3X28= 84 mm Total Diameter of All Cables laying in Tray = (119.4+137.2+54)mm Total Diameter of All Cables laying in Tray = 340.6mm Total Weight of Cables Passing in to Cable Tray: Weight of 300Sq.mm Cable =No of Cable X Weight of Each Cable Weight of 300Sq.mm Cable =2X5.9= 11.8 Kg/Meter Weight of 400Sq.mm Cable = No of Cable X Weight of Each Cable Weight of 400Sq.mm Cable =2X6.1= 12.2 Kg/Meter Weight of 25Sq.mm Cable = No of Cable X Weight of Each Cable Weight of 25Sq.mm Cable =3X0.5=…
