Electricity safety requires caution. X-ray imaging detection technology is used to detect cables

Due to electricity, humanity initiated the Second Industrial Revolution, represented by electrification, and deeply influenced the later Third Industrial Revolution and now the Fourth Industrial Revolution. Today, electricity has become an indispensable part of our production and daily life, with various power generation, consumption, transmission, and storage equipment scattered throughout factories, communities, and households. In modern society, we cannot do without electricity. No matter what we do, we cannot work without electricity. Electricity is very important for our lives, but accidents caused by electricity are also common. When it comes to electricity safety, we must always pay attention to it.

In the use of electricity, the use of cables is indispensable. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and so on. They are all composed of single or multiple wires and insulation layers, used to connect circuits, appliances, etc.

In recent years, with the continuous acceleration of urbanization in China, the demand for electricity in various fields has been increasing, which has led to the rapid development of the wire and cable industry. Related products have been widely used in fields such as electricity, construction, communication, and petrochemicals. According to the structural form, transmission lines can be divided into two types: overhead transmission lines and cable lines. Overhead transmission lines are mainly composed of wires, line fittings, overhead ground wires, insulator strings, towers, and grounding devices, which are installed on the ground. Cable lines are mainly composed of wire cores, insulation layers, shielding layers, and protective layers, and are mainly used for urban underground power grids, power station outgoing lines, internal power supply of industrial and mining enterprises, and underwater transmission lines crossing rivers and seawater.

From the above, it is not difficult to see that "electricity" is widely used in our daily lives, and wires and cables are indispensable. So, how should we determine whether there is a fault in the wires and cables? Recently, the editor learned about a new technology called "X-ray imaging detection technology" for detecting cables.

It is reported that X-ray imaging detection technology, as a real-time imaging non-destructive testing technology, uses X-ray to penetrate the interior of the tested object, process and convert the shooting results into digital signals, and present them in an image format. When using this technology for cable anomaly diagnosis, if there is a defect anomaly in the cable, the intensity of the radiation passing through the area will produce a blackness difference in the image, helping maintenance personnel quickly and accurately evaluate the location of the cable defect and visually analyze the degree of the defect.

In addition, X-rays are electromagnetic waves with extremely short wavelengths and high energy. The wavelength of X-rays is shorter than that of visible light (about 0.001~100 nanometers, while the wavelength of X-rays used in medicine is about 0.001~0.1 nanometers). The use of X-ray imaging detection technology can not only improve the detection rate of cable anomaly diagnosis defects, but also has the advantages of fast detection speed, strong instrument portability, and high detection sensitivity.

With the continuous development of urban construction, the use of cable lines will inevitably be fully popularized. We can apply X-ray imaging detection technology to diagnose and pulse cables, ensuring electricity safety.
