The IEC 60840 Cable Thermal Cycling Test System is designed for thermal cycling and heating-cycle testing of high-voltage cable systems and accessories.
The system uses controlled conductor current to heat the cable to the required operating-temperature condition and maintains the temperature according to the specified test procedure.
IEC-oriented cable thermal cycling applications commonly involve controlled conductor temperature, heating/cooling cycles, and voltage application during the specified test stage.
Power cables repeatedly heat and cool during actual operation because of changes in load current and environmental conditions.
These temperature changes can produce thermal and mechanical stress within the cable insulation, conductor, screen, sheath, joints, and terminations.
Thermal cycling testing allows manufacturers and laboratories to evaluate cable-system performance under controlled and repeatable conditions before commercial deployment.
Is this system suitable for IEC 60840 type testing?
It can be engineered for IEC 60840 test requirements. The exact configuration should be confirmed against the customer's cable rating and complete test procedure.
Does IEC 60840 testing require high current?
Yes. The cable conductor is heated by controlled current to achieve the required conductor temperature.
Can voltage be applied during heating?
Depending on the test configuration, the heated cable can be subjected to the required electrical stress using additional suitable HV equipment.
