Recently, Shanxi Electric Power Research Institute and Shanghai DEMIKS Electric Power Technology Co., Ltd. reached a cooperation agreement to purchase and apply the cable temperature rise testing system developed by Shanghai DEMIKS Electric Power Technology Co., Ltd. Judging from the project site photos, the system has been deployed at the power testing site, with the supporting high-current testing device, control cabinet, and data acquisition and monitoring unit operating in tandem, providing professional testing conditions for temperature rise testing of cables and related power equipment.
This collaboration represents a practical application of Shanghai DEMIKS Power Technology Co., Ltd.’s services to power research and testing institutions, and also reflects the Shanxi Electric Power Research Institute’s emphasis on the stability of testing equipment, the controllability of the testing process, and data management capabilities. By introducing a cable temperature rise testing system adapted to scientific research and testing scenarios, the Shanxi Electric Power Research Institute can further improve its power equipment testing processes and provide equipment support for the standardized implementation of related testing work.
To meet the needs of cable temperature rise testing, improve the testing process.
During long-term operation, cables are affected by factors such as load current, environmental conditions, laying method, and heat dissipation. The temperature rise of the conductor and connection parts directly affects the safety margin of equipment operation. Therefore, cable temperature rise testing is an important test in cable product performance evaluation, power equipment condition study, and engineering application verification.
The cable temperature rise testing system configured in this project employs a combination of a high-current output device and a test control unit. It applies a corresponding current to the object under test through the test circuit and controls and records the testing process. A centralized operation and monitoring interface is provided at the system’s front end, allowing testing personnel to view the operating status, adjust the test procedure, and monitor changes in key data.
It should be noted that the specific test current range, number of measurement channels, control accuracy, and supporting functions should be based on the project technical agreement, equipment nameplate, and formal acceptance documents. This article only introduces the equipment application scenarios based on project site photos and cooperation information.
Based on the on-site configuration, the system features multi-unit collaborative testing capabilities.
As can be seen from the on-site photos, the equipment mainly consists of the following types of units:
1. High Current Testing and Compensation Device
Multiple sets of blue box-type units were set up on site, forming test circuits via copper busbars and connecting conductors. This type of structure is typically used to provide the high current conditions required for testing to the cable or related conductor under test, and also facilitates circuit configuration and on-site adjustments according to different test objects.
2. Cable temperature rise test control cabinet
The control cabinet integrates operation buttons, status indicators, instruments, and a computer monitoring interface, enabling it to perform equipment start-up and shutdown, operational status observation, and test process management. This centralized control approach helps test personnel reduce on-site operational steps and improves the clarity of the test process.
3. Data Acquisition and Monitoring Unit
The monitoring interface shown in the image demonstrates that the system features multi-point information display and data monitoring capabilities. For cable temperature rise testing, continuously recording temperature changes at different measuring points helps testers analyze the heating process, determine the thermal stability state, and provides a data foundation for compiling test reports.
4. Supporting conditions for high-voltage testing site
Some of the on-site photos showcase the high-voltage testing area and related testing equipment at the Shanxi Electric Power Research Institute. The testing area employs isolation, warning, and zoned management methods, meeting the requirements for safety distances, on-site management, and operational order during power testing. The cable temperature rise testing system, used in this specialized environment, facilitates integration with power research, equipment testing, and comprehensive testing work.
Shanghai DEMIKS Power guarantees equipment application through project-based services.
For power research institutes, the procurement of cable temperature rise testing systems involves not only considering the functionality of individual devices but also the compatibility between the equipment and existing testing sites, power supply conditions, test objects, and management processes. Shanghai DEMIKS Power Technology Co., Ltd. completed the equipment configuration and on-site implementation based on the application scenarios of Shanxi Electric Power Research Institute, enabling the system to integrate into the existing testing environment and creating conditions for subsequent testing work.
During project implementation, power testing equipment typically undergoes stages including scheme communication, technical design, equipment manufacturing, on-site installation, commissioning, and acceptance. Targeted configuration based on cable temperature rise testing requirements helps improve equipment adaptability and facilitates subsequent testing of different types of tasks based on research objectives.
Supporting power research and equipment quality evaluation
As power transmission and distribution systems place higher demands on power supply reliability and equipment operational safety, the testing of cables and their associated equipment requires greater emphasis on process recording, data analysis, and result traceability. A stable cable temperature rise testing system can provide testing personnel with a relatively clear testing process and data management foundation, serving the following application areas:
- Study on temperature rise characteristics of cable conductors and related connection parts;
- Thermal stability and operational adaptability testing of power equipment;
- Performance verification of cables and related components;
- Data collection and analysis in power research projects;
- Equipment testing, product evaluation, and technological improvement.
This purchase of a cable temperature rise testing system from Shanghai DEMIKS Power Technology Co., Ltd. by the Shanxi Electric Power Research Institute will help further enrich the institute’s power testing equipment configuration and enhance its testing support capabilities for cables and related power equipment. In the future, both parties can continue to conduct exchanges and cooperation in areas such as the application of power testing equipment, optimization of testing technologies, and implementation of scientific research projects.
Conclusion
As can be seen from the equipment on-site and application environment, the cable temperature rise testing system provided by Shanghai DEMIKS Electric Technology Co., Ltd. has been integrated into the professional testing scenarios of Shanxi Electric Power Research Institute. This collaboration, based on actual testing needs, integrates high-current testing, process control, and data monitoring, providing new equipment support for cable temperature rise testing and related power research.
For research institutes, testing organizations, and power companies focusing on cable temperature rise testing systems, power testing equipment, and high-voltage testing equipment , equipment selection should be based on a comprehensive evaluation of the test object, testing standards, site conditions, and data management needs. Shanghai DEMIKS Power Technology Co., Ltd. will continue to provide more targeted power testing solutions based on customers’ actual applications.
