What is the meaning of mobile working temperature for cable applications ?
Mobile working temperature means that the cable can work flexibly and there will be no cracks in the cable sheath and insulators during operation. The cold bend test is conducted to measure this. After the cable is kept at the desired temperature, it is bent up to the minimum bending radius specified by the manufacturer. If no cracks are observed in the cable, it passes the test. It is generally used for cable designs with smaller diameters.
