Irradiated cross-linked power cable:
Irradiated crosslinked low smoke halogen-free flame retardant wire and cable have difficulty catching fire and have the ability to prevent or delay the spread of flame
Ability, over load strong, and once on fire, he has no halogen, low smoke, non-toxic, no corrosion and other characteristics, suitable
Such as high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, ores, petroleum, chemical
Work, etc.
It mainly includes: irradiation crosslinked low smoke halogen-free flame retardant polyethylene insulated wire, irradiation crosslinked polyethylene insulation control
Making cable, irradiation crosslinked low smoke halogen-free flame retardant control cable, irradiation crosslinked low smoke halogen-free flame retardant polyethylene insulation electricity Power cable.

1. Advantages of irradiation cross-linked cables:
High current carrying capacity: irradiated cross-linked cable, after being irradiated by high-energy electron beam, the molecular structure of the material changes from linear to three-dimensional network molecular structure, and the temperature resistance grade changes from non cross-linked
Increasing the temperature from 70 ºC to 90 ºC, 105 ºC, 125 ºC, 135 ºC, or even 150 ºC increases the current carrying capacity of cables of the same specification by 15-50%.
High insulation resistance: Due to the avoidance of using hydroxide as a flame retardant in irradiated cross-linked cables, it prevents pre crosslinking during crosslinking and the absorption of air by the insulation layer
The phenomenon of insulation resistance decreasing due to moisture content. This ensures the insulation resistance value.
Long service life and strong overload capacity: Due to the high temperature resistance and aging temperature of the irradiated cross-linked polyolefin material, the cycle time of the cable during use is extended
The service life of ring heating.
Environmental protection and safety: Due to the use of halogen-free and environmentally friendly materials in the cables, the combustion characteristics of the cables meet environmental requirements.
Product quality temperature: The quality of traditional warm water cross-linked cables is affected by factors such as water temperature, formulation process, cross-linking additives, etc., and the quality is unstable. However, irradiation cross-linked cables
The quality depends on the irradiation dose of the electron beam, which is controlled by a computer and eliminates human factors, resulting in stable quality.
2. Usage characteristics:
The rated voltage U of the power cable/ U is 0.6/1KV. The rated voltage U of the control cable/ U is 450/750V, and the rated voltage of the wire is U/ U is 450/750V and below.
The long-term allowable working temperature of the cable shall not exceed 135 ºC.
The ambient temperature during installation should not be lower than 0 ºC.
Minimum bending radius during cable installation:
A. Control cable: Cables without armor layer should not be less than 6 times the outer diameter of the cable, and cables with armor or copper tape shielding structure should not be less than 12 times the outer diameter of the cable.
