Irradiated low-smoke halogen-free wire and cable

This product is suitable for transmission of electric energy in power lines with a rated voltage of 0.6/1KV and below. Irradiation cross-linking is the use of high-energy β-rays generated by irradiation to form polymer free radicals, and then polymer free radicals recombine into cross-linking bonds, thereby turning the original linear molecular structure into a three-dimensional network molecular structure. Cross-linked.

This product is suitable for power transmission in power lines with a rated voltage of 0.6/1KV and below.    
Product Executive Standard: Enterprise Standard:Q/JS12.04-2011
Explanation of the principle of irradiation
Irradiation cross-linking is the use of high-energy & beta rays generated by irradiation to form polymer free radicals, and then polymer free radicals recombine into cross-linking bonds, thereby turning the original linear molecular structure into a three-dimensional network molecular structure. Form crosslinks.
Characteristics of radiation cross-linked low-smoke halogen-free wires and cables
Large current carrying capacity: irradiated cross-linked cables, after high-energy electron beam irradiation, the molecular structure of the material changes from linear to three-dimensional network molecular structure, and the temperature resistance level is increased from the non-crosslinked 70℃ to 90℃, 105℃, 125℃, 135℃, even 150℃, the current carrying capacity of cables of the same specification is increased by 15-50%.
Insulation resistance is large: because the radiation crosslinked cable avoids the use of hydride as a flame retardant, it prevents pre-crosslinking during crosslinking and the insulation layer absorbs air The phenomenon that the insulation resistance decreases due to the moisture. Thereby ensuring the insulation resistance value.
Long service life, strong overload capacity: due to the high temperature resistance grade and high aging temperature of the polyolefin material after radiation crosslinking, it prolongs the cycle of heating during use. Service life.
Environmental protection and safety: Since the materials used in the cables are all halogen-free and environmentally friendly materials, the combustion characteristics of the cables meet the requirements of environmental protection.
Product quality is stable: The quality of traditional warm water cross-linked cables is affected by water temperature, extrusion process, cross-linking additives and other factors, and the quality is unstable. The quality of radiation cross-linked cables depends on the radiation dose of the electron beam. The dose is controlled by a computer, without human factors, so the quality is stable.
Irradiation cross-linked low-smoke, halogen-free, flame-retardant wires and cables are difficult to catch fire and have the ability to prevent or delay the spread of flames. They have strong overload capacity. Moreover, once they catch fire, they have the characteristics of halogen-free, low-smoke, non-toxic, and non-corrosive. It is suitable for high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical industries, etc.
Irradiation cross-linked low-smoke halogen-free fire-resistant wire and cable not only meets the characteristics of irradiated low-smoke halogen-free flame-retardant cable, it can also meet the power supply capacity of the line under fire conditions, and has a strong overload capacity. Mainly used in fire alarm, fire fighting equipment, smoke exhaust equipment, emergency channel transportation, lighting and other emergency facilities in the power supply line where fire resistance is required.


Flame retardant grades of radiation cross-linked low-smoke halogen-free cables
According to the test conditions specified in GB/T18380.3-2002, the flame retardant grades of irradiated low-smoke halogen-free cables are divided into four grades: A, B, C, and D
