Scope

Formula example only. Cable manufacturer limits, raceway condition, lubricant, bend sequence, pulling setup, and qualified review govern pull acceptance.

Lookup table

Show basic pulling-tension and sidewall-pressure arithmetic relationships for preliminary pull planning.

Scroll sideways to keep row labels aligned with hidden columns.

Formula basis: straight-pull tension = weight x length x friction coefficient; sidewall pressure = tension / bend radius.

Notes
  • Check table values for preliminary lookup and arithmetic checks only.
  • Confirm equipment ratings, product markings, installation conditions, utility requirements, and the local authority requirements before design or field use.
