Five-core cable with shielding function

Abstract

The invention discloses a five-core cable with a shielding function. The cable comprises discs, an outer sheath, an inner core, a filler and an insulating sleeve. The discs are arranged at the left side and the right side of a cable winding and unwinding roller, a cable body is wound on the cable winding and unwinding roller, and the outer sheath is arranged on the outer surface of the cable body.A high-temperature-resistant layer is arranged at the inner side of the outer sheath, the outer sheath is made of a halogen-free flame-retardant polyolefin material component, and the high-temperature-resistant layer is mainly made of quartz sand; the inner side of the high-temperature-resistant layer is provided with an oil-proof layer, the oil-proof layer is made of butyronitrile polyethylene,and the inner side of the oil-proof layer is provided with an anti-magnetic radiation layer; the inner side of the anti-magnetic radiation layer is fixedly provided with a metal sheath, and the metalsheath is a copper material component. Accordig to the present invention, the anti-radiation layer and the shielding layer are arranged in the cable, so that the electromagnetic radiation possibly brought by the cable during the power transmission process can be eliminated, the body health of people is guaranteed, the shielding layer can shield the interference of the external signals, and the work requirement is met.

Description

technical field [0001] The invention relates to the technical field of cable equipment, in particular to a five-core cable with shielding function. Background technique [0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits power or information from one place to another. Traditional cables only have single-core or double-core inside, resulting in cable The ability to transmit power is insufficient, and the conduction speed will be greatly reduced, which cannot meet the needs of electric power work, and the inside of the traditional cable is not equipped with an oil-proof layer. The cables used in some factories will come into contact with oil or some corrosive This kind of liquid is easy to make the cable age rapidly, greatly reducing the service life of the cable, and the traditional cable is not equipped with an anti-electromagnetic radiation layer, the cable may generate some electromagnetic ...

[0002] A cable is usually made of one or more mutually insulated conductors and an outer insulating protective layer, which transmits power or information from one place to another. Traditional cables only have single-core or double-core inside, resulting in cable The ability to transmit power is insufficient, and the conduction speed will be greatly reduced, which cannot meet the needs of electric power work, and the inside of the traditional cable is not equipped with an oil-proof layer. The cables used in some factories will come into contact with oil or some corrosive This kind of liquid is easy to make the cable age rapidly, greatly reducing the service life of the cable, and the traditional cable is not equipped with an anti-electromagnetic radiation layer, the cable may generate some electromagnetic radiation during work, which will cause great harm to people's health. Threat, and the traditional cable is not equipped with a shielding layer, so the cable cannot isolate the signal connection with the outside world, and some concealed projects cannot use this type of cable, which cannot meet people's needs
