Product Description
The Power Cable Heating Cycle Test System provides controlled conductor heating for power cable thermal cycling and type-testing applications.
It is especially suitable for XLPE insulated HV and EHV power cables, where the cable needs to experience repeated temperature changes similar to those encountered during actual operation.
The system uses high-current heating technology to raise the conductor temperature and maintain the required thermal condition for a defined period before allowing the sample to cool.

Application Scenarios
Cable Manufacturers
Used during product development, type testing, qualification, and quality verification.
Cable Accessory Manufacturers
Suitable for testing cable joints, terminations, connectors, and other accessories together with the cable system.
Testing Laboratories
Provides a dedicated thermal cycling platform for customer-witnessed and certification-related tests.
Power Utilities
Can be used for research, qualification, and evaluation of cable systems intended for transmission and distribution networks.
Customer Concerns
Customers normally need to know:
- What maximum current is available?
- What cable cross-section can be tested?
- What temperature range can be achieved?
- How accurately is temperature controlled?
- How many cycles can be programmed?
- Can the test run automatically?
- Can data be exported?
- Can the equipment be customized?
- Can it be integrated with an HV test system?
The final system configuration should therefore be based on the cable specification and test standard, rather than simply selecting a fixed current rating.
FAQ
Does the system test only XLPE cables?
No. The system can be configured for different cable insulation systems and test specimens according to the customer's requirements.
Can it be used for EHV cable testing?
Yes. The system can be engineered for EHV cable applications, including prequalification-related testing.
Does the system include temperature sensors?
Yes. Temperature measurement and monitoring can be integrated into the control system.
