The Power Cable Thermal Cycling Test Equipment is designed not only for cable conductors but also for evaluating complete cable systems and accessories under repeated thermal stress.
Cable joints and terminations can experience significant thermal and mechanical stress when cable load changes during operation. Thermal cycling testing helps verify the performance and reliability of these components under controlled conditions.
Customers purchasing this type of equipment often focus on:
Cable size compatibility
The current output must match the conductor cross-section and required temperature.
Accessory installation
The test chamber, connection arrangement, cable routing, and fixture dimensions need to accommodate the complete test specimen.
Temperature uniformity
The system needs to maintain a stable and repeatable thermal profile.
Long-term operation
The equipment should be capable of operating reliably throughout the complete test program.
Integration capability
For qualification tests, thermal cycling may need to be combined with AC, DC, impulse, or partial discharge measurements.
Can cable joints and terminations be tested?
Yes. The system can be designed for complete cable accessory assemblies.
Can the cable be heated while high voltage is applied?
Yes, where required, the thermal system can be integrated with suitable HV test equipment.
Can the system be designed for submarine cables?
Yes. The design can take into account the cable size, length, accessory arrangement, current requirement, and environmental conditions.
