Calculation of Uphill Bends in Simple Cable Trays
Calculate horizontal, vertical, or compound cable tray offsets based on bend angle, offset distance, and available installation space. How to calculate cable tray bends? Calculate the minimum required bend radius by multiplying the cable's outside diameter by its bending factor (e. Then, select a standard tray fitting (300mm, 450mm, etc. ) that matches or exceeds this value. Pre-fab vs Field Bent: For standard offsets (6, 12, 18 in at 45°), use manufacturer pre-fabricated offset fittings to save. Subscribe to get the latest posts sent to your email. Faster Theme by Seos Themes As CDEF is a parallelogram DE = CF. The fold angle is AEF which will be half of FCB. Come to think of it, CB isn't right for the horizontal either. Drop a perpendicular down from F to CB, let it cross CB at B' and CB' = 170mm.
