Description
Technical Field
The utility model belongs to the technical field of the cable technique and specifically relates to an irradiation cross-linking does not have steamed low fire-retardant high performance cable of cigarette.
Background
Cables are typically made of two or more cores coated with a highly insulating material, with adjacent cores being insulated from each other. With the rapid development of economy and science and technology, cables are widely used in various places, such as power stations, railway stations, high-rise buildings, factories, oil drilling platforms and other fields. In case of fire, the flame often spreads along the cable, which easily causes great economic loss to people. Most of the existing cables are added with flame retardants for fire prevention, but most of the existing flame retardants are halogen-containing flame retardants, can generate a large amount of toxic gas when a fire disaster occurs, and cause secondary damage to people in the fire disaster.
In addition, the existing cable often needs to be moved in use, and the cable layer is easily scratched, so that accidents such as electric leakage and the like are caused.
