Abstract

The invention discloses an aluminum alloy conductor polypropylene insulated interlocking armored power cable, which comprises a conductor, an insulating layer, an inner shielding layer, a tape layer and an armoring layer. Set in the tape layer, the tape layer is covered with an outer shielding layer and a sheath layer from the inside to the outside in turn, the sheath layer is covered with an armor layer, and the conductors in each group are sequentially covered from the inside to the outside Cover the insulating layer and inner shielding layer; use aluminum alloy as the conductor material to greatly improve the mechanical properties of the conductor, avoid the problems of low elongation, poor creep resistance, and poor flexibility of pure aluminum conductors, and increase the cable system. Connection reliability; by setting the armor layer connected to the armor structure, the armor layer can be guaranteed to have strong tensile properties, and at the same time, the bending performance of the armored cable can be improved through the cooperation of the convex part of the connection ring and the sliding hole , to facilitate the arrangement of cables.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to an aluminum alloy conductor polypropylene insulated chain armored power cable. Background technique [0002] Aluminum alloy cable adds copper, iron, magnesium, silicon, zinc, boron and other alloy elements to electrical aluminum, and at the same time, through process adjustment, the mechanical properties of aluminum alloy conductors are greatly improved, avoiding the low elongation and creep resistance of pure aluminum conductors. The problems of poor variable performance and poor flexibility increase the connection reliability of the cable system. In addition, keep the electrical properties of aluminum alloys on the same level as electrical aluminum conductors, above 61% IACS. [0003] Alloy power cables make up for the shortcomings of previous pure aluminum cables. Although the electrical conductivity of the cable is not improved, the bending performance, creep resistance...
