Embodiment Construction

[0009] like figure 1 As shown, a new metal shielded power cable is composed of control core 1, grounding core 2, silver-plated steel tape armor layer 6, metal fiber braided shield layer 7, cross-linked polyethylene insulation layer 8, polychloride It is composed of vinyl insulation layer 9, low-smoke halogen-free sheath layer 10 and polyvinyl chloride sheath layer 12. The control wire core 1 is provided with three groups, which are composed of aluminum conductor 11, nitrile insulation layer 3 and silver-plated copper wire The shielding layer 5 is composed of one set of the grounding core 2, which is composed of an aluminum conductor 21, a nitrile insulating layer 3 and a galvanized copper wire shielding layer 4.

[0010] Specific implementation: the control wire core 1 and the grounding wire core 2 are extruded inside the silver-plated steel tape armor layer 6, and a layer of metal fiber braided shielding layer 7 is wrapped outside the silver-plated steel tape armor layer 6, s...

Abstract

The invention discloses a novel metal shielded power cable, which comprises three groups of control wire cores, one group of grounding wire cores, a silvered steel tape armor layer, a metal fiber-braided shielding layer, a crosslinked polyethylene insulating layer, a polyvinyl chloride insulating layer, a low-smoke halogen-free sheath layer and a polyvinyl chloride sheath layer, wherein each group of control wire cores comprise an aluminum conductor, a butyronitrile insulating layer and a silvered copper wire shielding layer; and the group of grounding wire cores comprise another aluminum conductor, another butyronitrile insulating layer and a galvanized copper wire shielding layer. The cable has the advantages of creep resistance, high flexibility, good water-proof capability and the like.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a novel metal shielding power cable. Background technique [0002] With the continuous development of my country's industry, my country has entered the era of electrification in an all-round way, and the use of power cables is also increasing. The main component of the conductor for manufacturing cables is copper, accounting for about 70% of the total amount of copper used. However, my country's copper resources are very short. With the depletion of China's copper mine resources, 80% of China's copper mines need to be imported, which is highly dependent. With the rising price of copper, replacing copper with aluminum is an inevitable trend in the development of wire and cable. More than 80% of the wires and cables in France are aluminum conductors, and the aluminum conductors in Japan also account for more than 50%. my country's aluminum resources are very rich, but the application amount...
