New electromagnetic protection technology: anti EMC electromagnetic interference/EMP cable applications

The global order has entered a period of deep adjustment, with the trend of multipolarization and geopolitical games running in parallel, economic recovery diverging, and the aftermath of epidemics intertwined with inflationary pressure. International trade friction and protectionism have not ceased, and emerging economies are seeking new momentum. Local wars and proxy conflicts continue, and tensions in the Middle East and Eastern Europe have escalated. Peace and security are facing a severe test, and international cooperation and dialogue need to be strengthened.

Modern society is highly dependent on electronics and information technology, and the “EMP event” in the Middle East in mid-June 2024, which caused a global sensation, could have triggered a chain reaction affecting a number of critical areas such as the banking system, transportation control, healthcare facilities, water supply and food supply chain. On the electromagnetic interference of some of the problems whether there is a solution to it, TST CABLES with everyone to take a look.

EMP, or Electromagnetic Pulse, is a short-lived but extremely intense phenomenon of electromagnetic field perturbation, capable of instantaneously generating a wide range of electromagnetic radiation. This phenomenon can occur naturally, such as with solar storms or lightning, or it can be artificially created, especially by nuclear explosions or non-nuclear EMP weapons (e.g., high-power microwave weapons).

First, anti-electromagnetic interference cable solutions and performance

  • Shielding design: these cables usually use a multi-layer shielding structure, such as copper braid, aluminum foil layer and highly conductive composite materials, forming a closed “Faraday cage”, effectively blocking the intrusion of external electromagnetic pulse, while reducing the internal signal leakage.
  • Low coupling coefficient materials: the use of insulating materials with low permeability and low dielectric constant reduces the propagation and coupling of electromagnetic energy within the cable, thus reducing the impact of interference.
  • Grounding design: Good grounding of the shield is critical to ensure that any electromagnetic energy that penetrates the shield is quickly exported, preventing it from building up inside the cable and interfering with the signal.
  • Reinforced Construction: In order to cope with the physical impacts that EMI/EMP can cause, these cables may also be designed with a reinforced mechanical structure to ensure that normal function is maintained in extreme environments.
  • Redundant design: In some critical applications, dual or multiple backup line design is used, even if the main line is damaged, but also through the backup line to maintain the continuity of communication or power supply.

Second, anti-electromagnetic interference cable application areas

  • Military defense: to protect command and control centers, radar stations, missile launch systems and other sensitive military facilities from EMP attacks.
  • Critical Infrastructure: Ensure the stable operation of power grids, data centers, nuclear power plants, oil and gas fields, medical care, communication base stations and other national critical infrastructure.
  • Aerospace: for aircraft, satellites and other equipment that need to work in complex electromagnetic environments, to ensure the safety of their electronic systems.
  • Transportation: railroad signal system, marine navigation equipment, etc., to ensure the stability and safety of the transportation system.

Third, anti-electromagnetic interference cable performance indicators

  • Shielding effectiveness: a measure of the cable’s ability to resist external electromagnetic interference, usually expressed in decibels (db). Scientific research level shielding room is divided into three levels, of which the shielding rate of the second level of shielding room up to dB60, which means that in a specific frequency band can achieve 99.9% shielding effect. Such shielding performance is sufficient to meet the requirements of most scientific research experiments on EMP protection, can effectively isolate the external electromagnetic interference, to protect the laboratory precision instruments and experiments are not affected. Efficient and stable anti-EMP cable should have more than 100dB shielding performance, can effectively isolate most of the electromagnetic pulse interference.
  • Transmission loss: In order to ensure the integrity of the signal at the same time, anti-interference cable also need to minimize the signal attenuation in the transmission process, which is particularly important for high-frequency signals. Excellent cable design can balance the shielding effect and signal attenuation to ensure the accuracy of data transmission.
  • Durability and environmental adaptability: In addition to anti-EMI / EMP capabilities, such cables also need to have excellent abrasion resistance, corrosion resistance, as well as in extreme temperatures, humidity, chemical corrosion in the environment of the stability of the ability to work to ensure long-term reliable use.
  • Compatibility and flexibility: in the design of the compatibility with existing systems, as well as flexibility in the installation and maintenance, so that anti-EMI cables can be seamlessly integrated into various types of complex systems, easy to upgrade and maintenance.

Fourth, anti-electromagnetic interference cable development trend

  • Application of new materials: with the progress of materials science, the development of new shielding materials and insulation materials will greatly enhance the cable’s anti-interference capability and durability, such as the application of nanomaterials and smart materials.
  • Intelligent design: Incorporating sensors and intelligent monitoring systems, the cables are able to self-diagnose EMI conditions, provide timely warnings of potential EMI risks, and realize preventive maintenance.
  • Lightweight and miniaturization: Reduce the weight and size of cables while maintaining high performance to adapt to a wider range of application scenarios, especially aerospace and portable military equipment.
  • Integrated solution: Provide a total solution including cables, connectors and splices to ensure the consistency and reliability of the anti-interference performance of the whole system.

Anti-electromagnetic interference cables are an important means of protection in modern informationized warfare and complex electromagnetic environments. Through the special design of the cables, they are able to provide reliable signal transmission and power supply under extreme conditions, and protect critical equipment from damage caused by electromagnetic pulse, thus maintaining national security and social stability. With the continuous progress of technology, the performance of these anti-EMI cables will be more optimized, and the scope of application will be further expanded.
