Download RIGID: Conduit Bending Calculator and enjoy it on your iPhone, iPad, and iPod touch. Enter the known dimensions in the HellermannTyton online heat shrink calculator. Calculate: Conduit Size Needed Based on Cables % Conduit is filled. If the obstruction is 10" wide, you will now have marks at 50", 40" and 27". The only tools you need for more complex bends are an angle finder and a cheap scientific-type hand calculator or, in today's world, a smartphone with a calculator. dl = change in object length (m, inches) L0 = initial length of object (m, inches) α = linear expansion coefficient (m/moC, in/inoF) t0 = initial temperature (oC, oF) t1 = final temperature (oC, oF) The final length of the object can be calculated as L1 = L0 + dl = L0 + L0 α (t1 - t0) (2) where L1 = final length of object (m, inches). Shrinkage for Conduit Bending Explained Craig Michaud- Electrical Instructor 48. or a bender calculator that accounts for gain and shrink. When measuring for a rolling offset, place the tape measure from one conduit to the other at right angles to the conduit. 250" shrink per inch of offset 45° 3/8" =. SIMpull® Cable Pull Calculator Estimate and Manage Your Projects Use this simple tool to calculate conduit size and fill percentage, pulling tensions, cable sidewall pressure, jam probability, voltage drop, ground wire sizing, and more. Add the shrinkage amount given in this calculator to this dimension and make your first mark on the conduit. Electrical Conduit Math For nonstandard angles, C can be calculated by subtracting the cotangent Shrink on a 90 will vary by conduit size and bender shoe size. To determine the size of conduit you need in order to fit your chosen cable, enter your Belden cable part number or the diameter of your cable. radius and a 90 degree bend into the Developed Length Calculator we find that the gain or shrink is 8 9/16 inches. The height of the swept section of conduit is 2*Rcl*sin (A) + straight*cos (A) The maximum bend angle, with no straight section between bends, is 29 degrees. 4 mm) Sharp Bend 1994 – 2009 Swagelok Company Slide-Chart by PERRYGRAF, L. Input everything into the bend allowance formula: BA = angle × (π/180) × (radius + K-factor × thickness). When measuring for a rolling offset, place the tape measure from one conduit to the other at right angles to the conduit. Note: The values calculated for this question will be used in additional questions. " To determine the size of conduit you need in order to fit your chosen cable.
