Spiral Cable is a straight wire cable twisted by one or several groups of insulated wires. The spiral state is completed on the metal core rod, and then it is cooled and cooled after 30 minutes to 120 minutes of heat processing and shaping in the drying room. There are air cooling and water cooling. Spiral Cable is stretchable in a spiral state (the time is determined by the temperature and the sheath material).
