First, the explanation of the principle of radiation:
Irradiation cross-linking is the use of high-energy electron beam generated by an electron accelerator to bombard the insulating layer and sheath, break the polymer chain, and break every broken point into free radicals. The radicals are unstable and recombine with each other. After recombination, the original chain-like molecular structure becomes a three-dimensional network-like molecular structure and forms a crosslink. Second, the characteristics of irradiation cross-linked low-smoke halogen-free wire and cable 1, the large flow rate; irradiation cross-linked cable, after irradiation by high-energy electron beam, the molecular structure of the material from linear to three-dimensional network molecular structure, temperature resistance Grades are increased from non-cross-linked 70 °C to 90 °C, 105 °C, 125 °C, 135 °C, even 150 °C, than the same size of the cable's current-carrying capacity increase 15-50%.
2. Insulation resistance is large; the use of hydroxide as a flame retardant is prevented by irradiating cross-linked cables, thus pre-cross-linking during cross-linking and insulation resistance drop due to absorption of moisture in the air by the insulating layer are prevented. In order to ensure the insulation resistance value.
3, long service life, strong overload capacity; due to irradiation of polyolefin materials after crosslinking high temperature rating, high temperature, so extend the life of the cable in the process of using the cycle of heat.
4, environmental protection, safety; because the cable used in the materials are halogen-free environmentally friendly materials, so the cable's combustion characteristics meet environmental requirements.
5, product quality temperature; the quality of the traditional warm water cross-linked cable is subject to water temperature, agent manufacturing process, China wire and cable network. Com crosslinking additives and other factors, quality instability, and the quality of irradiation cross-linked cable depends on the electron beam irradiation dose, irradiation dose is controlled by the computer, less artificial factors, so the quality is stable.
Irradiation cross-linked low-smoke halogen-free flame-retardant wire and cable have the ability to prevent fire and have the ability to prevent or delay the spread of flame. The overload force is strong, and once it catches fire, it is halogen-free, low-smoke, non-toxic, non-corrosive, etc. Yuru High-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, ore, petroleum, chemicals, etc.
