Mineral insulated fireproof cable
Mineral insulated fireproof cable: 
Good fire resistance (as per BS6387): In the event of a fire, the metal sheathed inorganic mineral insulated cable can continuously supply power (withstand a high temperature of 950-1,000℃ for more than 3h), and can withstand the water during firefighting and the mechanical impact caused by the falling objects from a building catching fire, providing protection for evacuation and rescue. 
Strong overload capacity: The working temperature and overload capacity of the cable are mainly affected by the cable's insulation material. The metal sheathed inorganic mineral insulated cable uses synthetic mica material with a temperature resistance greater than 1,000℃, which is more than 10 times higher than ordinary plastic, so it has a good overload capacity. 
Application: Fire protection systems of all types of buildings; and important places such as control centers for hospitals, commercial districts, airports, petroleum, chemical, nuclear power,  national defense construction, aerospace, satellite launch, etc. 
Aluminum alloy conductor cable
Aluminum alloy conductor cable: 
It has been widely used in residential, commercial, and industrial projects with its safety, reliability, stable operation and high cost performance. At present, it has reached an application scale of about 80% low-voltage cables and 40% medium-voltage cables. By replacing pure aluminum conductors with rare-earth high-iron aluminum alloy, the defects of traditional pure aluminum cables, namely poor creep resistance and corrosion resistance, are made up, and such performance as high flexibility, strong extension, low rebound and stable connection is gained. The use of rare earth and cross-linked polyethylene insulation makes the cable better resistant to heat and carry more current than ordinary cables. 
The rare-earth aluminum alloy conductor is based on AA8030 aluminum alloy, with the addition of rare earth elements, making its conductor resistance, strength, creep performance, corrosion resistance, and elongation performance more superior. 
Cables for photovoltaic power generation systems
Cables for photovoltaic power generation systems: 
It is mainly used for the connection between solar cell modules, storage batteries, AC loads, solar cell arrays, and between storage batteries (battery packs) and inverters in photovoltaic power stations. 
Its service environment is harsh. The cable sheath of ordinary cables used in such environment for a long time will be fragile, and even the cable insulation layer may decompose, thereby directly damaging the cable system, increasing the risk of cable short circuit, and then greatly affecting the service life of the system. To this end, photovoltaic cable is weatherable, resistant to ultraviolet and ozone, and can withstand a wider range of temperature changes. 
Photovoltaic cable, also known as a dedicated photovoltaic cable, is mainly used in photovoltaic power stations. It has the advantages of high temperature resistance, cold resistance, oil resistance, acid and alkali resistance, UV protection, flame retardant, environmental protection, long service life, etc., and is mainly used in harsh weather conditions. Common models are PV1-F, and H1Z2Z2-K. 
Silicone rubber car wire
Silicone rubber car wire: 
It is a wire material used in automotive electrical systems, and consists of conductive copper or aluminum cores covered by a silicone rubber insulation layer. 
As an insulating material, silicone rubber has the following characteristics: 
1.High temperature resistance: Silicone rubber can work at high temperatures (150~200℃), which ensures the safe use of wires in high temperature areas such as engine room. 
2.Low temperature resistance: Silicone rubber maintains good flexibility and insulation performance at low temperatures. 
3.Excellent aging resistance: Silicone rubber is highly resistant to weather and light, and resists ultraviolet radiation, chemical erosion and aging. 
4. Flame retardancy: Silicone rubber can effectively prevent fire spread even in the event of, for example, short circuit due to its excellent flame retardancy. Silicone rubber automotive wires are suitable for low-voltage parts of automotive circuit systems, such as lights, audio, electric windows, and central control systems. 
Automotive irradiation wire
Automotive irradiation wire: 
It is a specially treated wire material. The common treatment method is electron beam irradiation, which is a technology that uses high-energy electron beam to irradiate materials. The physical and chemical properties of materials can be changed by adjusting the irradiation dose. It has the following characteristics: 
1.Enhance insulation performance: The insulation layer of an irradiated wire has higher mechanical properties. 
2.Improve temperature resistance: Irradiation treatment can improve the temperature resistance of the wire, so that it can work in a larger temperature range. 
3.Improve aging resistance: Irradiation treatment can make the insulation layer of the wire better resistant to aging. 
Automotive irradiated wires are widely used in automotive electrical systems, especially for parts that require high safety, such as electrical wiring in the engine room and body. Such wires can work stably for a long time in harsh environments, providing a reliable power supply for vehicles. 

Case presentation

Case study - irradiation application

Radiation application - pharmaceuticals and medical devices

Medical devices in use are required to be sterile, making it necessary to control the content of microorganisms at a low level. Manufacturers use ethylene oxide gas to sterilize products to inhibit the growth of microorganisms on the surface of a device. During use, there may be residual ethylene oxide, which can cause harm to human body. The emergence of electron irradiation technology has precisely solved this problem. Electronic accelerators can effectively kill bacteria, avoid contact infection to patients' open wounds, and also avoid secondary damage from ethylene oxide.

Similarly, the bacterial contamination of women and children's products in the production process will directly affect the health of children, so it is necessary to sterilize such products as per the health requirements.

Most Chinese patent medicines and some western medicines can be sterilized by irradiation, thereby effectively killing harmful bacteria in Chinese patent medicines and health products, so as to meet the practical and hygienic requirements. This is especially suitable for medicinal powder and Chinese patent medicines that are not resistant to high temperature and contain volatile components.

Irradiation application - food

Irradiation of food can inhibit physiological growth and prolong shelf life. For example, irradiation of garlic in large quantities can inhibit its physiological growth and achieve the purpose of preservation. Irradiation of fresh fruits and vegetables can inhibit enzyme activity, delay ripening, and prolong shelf life.

Insecticidal property and sterilization: Kill pests in cereals, bacteria in condiments and dehydrated vegetables, food-borne pathogenic bacteria in food, etc.

Preservation of frozen livestock, poultry, meat and seafood: The high-energy accelerator electron beam has high energy and high processing speed, which is suitable for frozen food that needs to be irradiated in time.

Degradation and destruction of harmful residues and food allergens in food.

Quarantine treatment by irradiation for import and export.

Irradiation modification - wire, cable, and sheet

Irradiation processing will change the molecular structure to a certain extent, and promote the stereo-linkage of chemical bonds in polymer materials, so as to make the structure more stable. This is common in wire and cable processing. After irradiation processing of PVC, PE, PTFE and other materials, the molecular structure of the cable cover forms stereo-crosslinking, and the degree of compactness is far beyond that of conventional products.
It not only significantly improves the physical indicators of the cable such as flame retardant, insulation, and environmental adaptability, but also improves the electrical performance of the product. PTFE, a very important high-temperature resistant material in aerospace field, is obtained by improving its performance through electron accelerator irradiation. The service life of an irradiated cable can be effectively prolonged.
