Cable Pulling Calculator

ICEA P-45-482 · BS 8010-2.1

Calculate pulling tension and sidewall bearing pressure for cable installation in ducts and conduits. Define multi-section routes with straight runs, bends, and inclined sections.

T_out = T_in × e^(μθ) at bends (capstan equation)• T = μWL for straight sections• SBP = T / R (N/m)• Conduit fill & jam ratio checks
