The sheath and insulation are easily damaged in frequent moving situations. The maximum operating temperature can only reach 200°C and cannot be used in higher environments. For cables that need to be resistant to high temperatures and need to be moved frequently, a new type of tensile, wear-resistant and high temperature resistant soft cable is needed to meet the use requirements.
