Five-core type cable with shielding function

Abstract

The invention discloses a five-core type 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 on the left and right sides of a cable reel, a cable body is wound on the cable reel, the outer sheath is disposed on the outer surface of the cable body, and an inner side of the outer sheath is provided witha high-temperature resistant layer. The outer sheath is made of a halogen-free flame-retardant polyolefin material member, the main material of the high-temperature resistant layer is quartz sand, aninner side of the high-temperature resistant layer is provided with an oil-proof layer, the material of the oil-proof layer is nitrile polyethylene, an inner side of the oil-proof layer is provided with a magnetic radiation prevention layer, a metal sheath is fixed to an inner side of the magnetic radiation prevention layer, and the metal sheath is a copper material member. According to the cableof the invention, a radiation shielding layer and a shielding layer are set in the cable, the electromagnetic radiation that the cable may bring during power transmission can be eliminated, the health of people is ensured, the shielding layer can shield the interference of external signals, and work requirements are satisfied.

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
