Silvered steel tape shielded power cable

Abstract

The invention discloses a silvered steel tape shielded power cable, which comprises three groups of control wire cores, one group of grounding wire cores, a silvered steel tape armor layer, a silvered steel tape shielding layer, a silvered copper tape screened 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 a silvered copper conductor, a butyronitrile insulating layer and a silvered copper wire shielding layer; and the group of grounding wire cores comprise another silvered copper 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 silver-plated steel tape 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 wires and cables in France are silver-plated copper conductors, and aluminum conductors in Japan also account for more than 50%. my country's aluminum resources are very rich, but the a...
