Description

Technical Field

[0001] The utility model relates to the field of green and environmentally friendly cables, in particular to a green and environmentally friendly cable. Background Art

[0002] With the continuous progress of human society, people's awareness of environmental protection has gradually increased. Ecological environment, environmentally friendly products, "green" food, and "green" projects have become one of the focuses of people's attention. In the wire and cable industry, there are also clean cables, "green" cables, and environmentally friendly cables. Green wires and cables should have the following characteristics: First, the raw materials and auxiliary materials used in manufacturing should not pollute the surrounding environment. Second, the wire and cable materials do not contain halogens such as bromine and fluorine. In emergency situations (such as electrical accidents and fires), no harmful gases, corrosive gases and other secondary pollution should be generated.

[0003] Existing environmentally friendly cables have low flame retardancy and are easily burned in high-temperature combustion environments. They also have low tensile strength during use and are easily damaged by ice on the outside of the cables in low-temperature freezing environments. They also have low curling and stretching properties.

[0004] Therefore, those skilled in the art provide a green and environmentally friendly cable to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings existing in the prior art and to propose a green and environmentally friendly cable. The reflective strips on the outer surface of the fireproof sleeve emit light at night so that people can stay away from the cable and prevent safety hazards. The tensile layer on the outer surface of the thermal insulation layer can enhance the strength of the cable so that the cable has high tensile strength during use. The outer surface of the thermal insulation layer is fixed with a fixed metal ring to fix the internal structure of the thermal insulation layer, making the internal structure more firmly fixed. The flame retardant outer layer can prevent the spread of fire when the cable is burned. The first shielding layer inside the flame retardant outer layer can transmit electricity to the ground wire when there is leakage inside the wire. The flame retardant inner layer can prevent spontaneous combustion inside the cable.

The thermal insulation layer can reduce the internal temperature of the cable when it is burned. Three second shielding layers are arranged inside the thermal insulation layer, which can shield the electromagnetic field generated when current passes through the conductor body. The flame retardant outer layer can prevent the spread of fire when the cable is burned. The first shielding layer inside the flame retardant outer layer can transmit electricity to the ground wire when there is leakage inside the conductor. The flame retardant inner layer can prevent spontaneous combustion inside the cable. The anti-slip cover of the flame retardant outer layer can prevent the cable from burning in the event of a fire, and can also maintain the internal temperature in winter.

[0010] Through the above technical solution, the conductor body can transport electricity, and an insulating layer is fixed on the outside of the conductor body to insulate the conductor body from adjacent bodies, so that the conductor body can operate normally.

[0011] Furthermore, a luminous reflective strip is fixedly provided on one side of the outer surface of the fireproof cover;

[0012] Through the above technical solution, the reflective strips on the outer surface of the fireproof cover emit light at night so that people can stay away from the cables and avoid safety hazards.

[0017] Furthermore, a plurality of fixed metal rings are fixedly provided on the outer surface of the heat insulation layer;

[0018] Through the above technical solution, the outer surface of the heat insulation layer is fixed with a fixing metal ring, which can fix the internal structure of the heat insulation layer, making the internal structure more firmly fixed.

[0019] Furthermore, the threaded sleeve on one side of the fixed metal enclosure is provided with two fixing screws;

[0020] Through the above technical solution, the fixed metal enclosure is fixed by means of fixing screws, and the tightness of the fixed metal enclosure and the fixed fireproof cover can be adjusted by rotating the fixing screws.
