Cable Pulling

Cable Pulling Analysis

Cable Pulling Analysis accounts for multiple cables of different sizes and allows complex 3D pulling path geometry.

Accurate prediction of cable pulling tension is essential for the proper design of cable systems. This knowledge makes it possible to avoid under-estimated and/or over conservative design practices to achieve substantial capital savings during construction.

A point-by-point calculation method is performed at every conduit bend and pull point. Both the forward and reverse pulling tensions are calculated for determining the preferred direction of pull.
