K3 Grade Signal Control Cables
1.Scene Introduction
As an important part of the global energy sector, the nuclear power industry is vital for its safety and stability. In the complex systems of nuclear power plants, K3 grade signal control cables play a key role in transmitting control signals and ensuring the normal operation of equipment. These cables not only need to maintain stable performance in extreme environments, but also need to meet strict safety and environmental standards.
2.The pain point analysis
Traditional cable systems may face multiple challenges in nuclear power plant environments, such as radiation, high temperature, high pressure, and chemical corrosion. These issues may lead to cable performance degradation, unstable signal transmission, and even cause safety hazards. Therefore, it is particularly important to develop a K3 grade signal control cable that can operate stably in a nuclear power environment for a long period of time.
3.The nuclear power K3 signal control equipment on the cable requirements
Nuclear power K3 signal control equipment on the cable requirements are extremely high, mainly including:
Radiation resistance, to ensure that the high radiation environment in the nuclear power plant cable performance is not affected.
High temperature resistance to adapt to the high temperature environment inside the nuclear power plant.
Excellent electrical performance to ensure the stability and accuracy of signal transmission.
High mechanical strength and corrosion resistance to resist the influence of external physical and chemical factors.
4.Certification Standards
Nuclear power K3 signaling control cables must comply with the relevant standards and regulations of the International Atomic Energy Agency (IAEA) as well as the nuclear power safety regulatory bodies of various countries. In addition, the cables are required to pass a series of stringent tests and certifications. For example, the cables should be able to withstand the bunched combustion test specified in the GB/T 18380.3 (IEC332-3) standard, as well as the vertical combustion test specified in the GB/T 18380.1 (IEC332-1) standard. Meanwhile, the low-smoke performance of the cable shall comply with the provisions of GB/T 17651 (IEC61034) standard, and the light transmittance shall be more than 60%; while the low-halogen performance shall comply with the provisions of GB/T 17650.2 (IEC60754-2) standard, and the PH value shall be not less than 4.3, and the conductivity shall be less than 10μs/mm.
Including but not limited to radiation resistance test, high-temperature aging test, electrical performance test.

7.Technical Tests
To ensure that the quality and performance of the cables meet the requirements of nuclear power class K3 signaling control equipment, TST CABLES has conducted a series of rigorous technical tests. The tests mainly include the following aspects:
Electrical performance test: verify whether the electrical performance of the cable meets the design requirements by measuring the cable’s resistance, insulation resistance, voltage withstand and other parameters. At the same time, the cable is tested for high-frequency signal transmission to ensure that it can accurately and stably transmit signals.
Environmental adaptability test: simulate the harsh environment of nuclear power plant with high temperature, high humidity, high radiation, etc., and carry out long-time operation test on the cable. Observe the performance changes of the cable in the harsh environment to verify whether it has good environmental adaptability.
Flame-retardant performance test: In accordance with the international standard flame-retardant test methods, the cable is tested for flame-retardant performance. By measuring the burning speed, smoke density and other parameters of the cable, we evaluate whether its flame retardant performance meets the requirements.
Mechanical performance test: The cable is tested for mechanical performance such as tensile, bending and twisting to verify whether it has sufficient mechanical strength and flexibility to meet the installation and operation requirements in the complex environment of nuclear power plants.
After the above tests, this nuclear power K3 signaling control cable solution has excellent performance in all performance indicators and fully meets the relevant standards and requirements of the nuclear power industry.
