The TPU materials type raw cable jacket can guarantee longer lifetime and quality. Coiled cable can be used to carry electrical currents as well as data and signal for telecommunications applications. This versatility makes coil cords ideal for use in environments that are often too rough for non-coiled cable.
It has the ability to extend beyond the natural length at rest, which can be a real space-saving feature. These cords are flexible beyond simple extending and retracting in that they can also be pulled, bent, and twisted without experiencing the metal fatigue of a straight cable.
