1 Νοε 2001 · If you're pulling a multiconductor cable, use the single-conductor equation. Looking at Table 5, you can see that as you increase the bend radius, the SWBP decreases. In addition, each equation defines the specific conductor in each conductor position that will experience the maximum crushing force: Cradle position: center conductor.
This article explains how to perform cable pulling tension and cable sidewall pressure calculations and also includes a worked calculation example.
Formation – Match the arrangement in which the cable(s) are pulled. Installation – Specify the conduit/duct dimensions, direction of pull, reel back tension and reduction factor. Friction – Enter the values for friction along the route including for the bends which result in high sidewall pressures.
6 Ιαν 2024 · Formula of Cable Pulling Force Calculator. The calculation formula for determining the pulling force (F) involves two primary variables: Cable Pulling Tension (T) and the Weight of the cable (W), calculated as:
11 Οκτ 2000 · For cable equipped with pulling eye or pulling bolt, the formula shown below is used to calculate the maximum allowable pulling tension on the cable for the entire routing. Tm = K x n x CMA (Formula 1) Where:T m = maximum pulling tension (lbs.) (see Appendix A for calculated tensions) K = constant.
29 Οκτ 2024 · The calculator will calculate the tension in each cable and provide individual capacities for each cable. Pulling Cable System - this will calculate the cable pulling tension due to the friction forces caused from pulling an object along a surface. This calculation requires the coefficient of friction between two surfaces.
3 Οκτ 2024 · The wire pull force (WPF) can be calculated using the formula: \ [ WPF = \frac {u \cdot d^2 \cdot L} {M \cdot I} \] Where: \ (WPF\) is the wire pull force in pounds (lbs), \ (u\) is the coefficient of friction, \ (d\) is the conduit inner diameter in inches (in), \ (L\) is the length of the run in feet (ft), \ (M\) is the material factor,
