A colored thread is placed between the cable insulation and overlying protective layers of each of the three phases of the cable. Each thread is a different color and continous thruout the cable length so that the phases can be easily identified on each end, making the cable easier to splice and test. The type of thread is so designed as to have enough strength that it can serve as a ripcord to facilitate the removal of protective layers. This reduces the likelihood that the insulation is damaged during preparation for splicing. It also facilitates the removal of said layers in the event of a manufacturing defect.
