Application of Cables in Nuclear Power Sensors
1. Scene Introduction
With the rapid development of nuclear power technology, the safe and stable operation of nuclear power plants is crucial to guarantee national energy security and ecological environment. Sensors, as key equipments in nuclear power plants, are responsible for real-time monitoring of various operating parameters, providing important data for safety control and operation management of nuclear power plants. As a key component connecting sensors and data processing system, the performance and quality of nuclear power sensor cable directly affects the monitoring effect and operation safety of nuclear power plant.
2.The pain point analysis
In the field of nuclear power, the application of sensor cables faces many challenges. First of all, the operating environment of nuclear power plants is complex, the cable needs to withstand high temperature, high pressure, high radiation and other harsh conditions, and at the same time to ensure the stable transmission of signals. Secondly, the sensor cable needs to have good electromagnetic shielding performance to resist external electromagnetic interference and ensure the accuracy of the data. In addition, the cable selection, process and installation, etc. also need to reach high standards to meet the long-term stable operation of nuclear power plants.
3.The nuclear power sensor cable requirements
Nuclear power sensor cable requirements are mainly reflected in the following aspects:
Electrical performance: the cable should have excellent electrical conductivity and insulation to ensure the accurate transmission of signals; at the same time, the impedance matching and attenuation characteristics of the cable should also meet the requirements to reduce signal loss.
Environmental adaptability: the cable should be able to work normally in harsh environments such as high temperature, high pressure and high radiation, and it should have good weather resistance and corrosion resistance.
Electromagnetic shielding performance: the cable should have good electromagnetic shielding effect to resist external electromagnetic interference and ensure signal stability and accuracy.
Mechanical and physical properties: the cable should have sufficient mechanical strength and flexibility to adapt to the complex environment of the nuclear power plant installation and operation requirements.
4.The nuclear power sensor cable certification standards
Nuclear power sensor cable certification standards are strict and diverse, demanding, including the International Atomic Energy Agency (IAEA) standards, IEEE standards, IEC standards and national nuclear safety regulations. These standards on the electrical performance of the cable, environmental adaptability, electromagnetic shielding performance, mechanical and physical properties, etc. have made detailed provisions to ensure that the cable in the nuclear power plant in the safe and reliable operation.
5. Cable selection
For the special needs of nuclear power sensors, we recommend the selection of PEEK cables with excellent electrical performance, environmental adaptability and electromagnetic shielding performance.
In terms of material selection, we use low-smoke halogen-free flame retardant, high-temperature, radiation and corrosion-resistant high-performance materials;
In structural design, we adopt multi-layer shielding structure, small volume, light weight, and effectively reduce electromagnetic interference;
In the production process, we strictly control each link to ensure that the quality and performance of the cable reaches the best state.
Selection parameters for reference (can be customized according to actual needs)
Long-term temperature resistance: -50-250℃

10.The actual application of nuclear power sensor cable program examples
A large nuclear power plant off the coast of China decided to upgrade the existing sensor cable system in order to improve its operational efficiency and safety. After market research and technology comparison, the nuclear power plant finally chose TST CABLES for its customized nuclear power sensor cable solutions.
In the course of the project, TST CABLES first conducted a detailed study of the operating environment of this nuclear power plant, including factors such as temperature, humidity, radiation levels, etc., to ensure that the selected cable materials could adapt to these extreme conditions. Subsequently, we developed cable specifications, lengths and connections based on the type and distribution of sensors to meet the data transmission needs between different sensors.
For cable selection, TST CABLES used special cables with excellent electrical properties and environmental adaptability. These cables are not only able to operate stably under high temperature, high voltage and strong radiation environments, but also have good electromagnetic shielding properties to ensure the accuracy and reliability of nuclear power sensor data.
After the completion of the project, TST CABLES conducted comprehensive testing and acceptance of the nuclear power cable system. The results show that the nuclear power sensor cable solution fully meets the operational requirements of nuclear power plants, and the efficiency and accuracy of sensor data transmission has been significantly improved. In addition, TST CABLES nuclear sensor cable solution also improves the safety and stability of nuclear power plants, providing a strong guarantee for the long-term operation of nuclear power plants.
