Measures for pulling and stretching electrical wires connected to distribution boxes
Use spool rollers (Figure 4) that allow spools to rotate in place and release wire smoothly without twisting. There are four key operating components used in an overhead distribution stringing job: the tensioner, pulling line (bull line), stringing blocks, and the puller. These key pieces should work together, and if any one of these components is deficient, either in design or performance, it directly. Conduit installation, wire pulling, and termination are interdependent tasks that must be carried out in a specific sequence to ensure the safety and functionality of the electrical system. Pulling devices include pulling ropes, swivels, pulling eyes, and pulling grips (crimp-on and basket type). The conductors of the cable are generally the only members that can bear the pulling forces. Conductor stringing is the process of installing overhead power lines or conductors onto transmission towers or distribution poles.
