Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] The structure of the present invention is as figure 1 As shown, it includes a central steel strand layer 1 formed by concentrically twisting several steel wires. The central steel strand layer is cabled by several tightly pressed tile-shaped conductors 2 around it. After cabled, the outer layer is wrapped with a semi-charged 3. The extruded semi-conductive layer 4 is extruded and wrapped with an insulating layer 5; the tile-shaped conductor 2 is formed by twisting and pressing several aluminum wires, and each tile-shaped conductor 2 is wrapped with a semi-conductive tape 6.

[0011] The insulating layer 5 is cross-linked polyethylene insulating material. The voltage level of the cable is determined by the insulation layer, generally 10KV, 20KV, 35KV.

[0012] The semiconductive tape 6 is a cross-linkable semiconductive shielding materi...

Abstract

The invention provides a segmental conductor-type steel core aluminum stranded wire overhead insulated cable, which comprises a central steel stranded wire layer formed by concentrically stranding a plurality of steel wires. A plurality of strands of tightly-pressed tile conductors are arranged around the central steel stranded wire layer for cabling, a semi-charged layer is wrapped at the outer layer after cabling, a semi-conductive layer is extruded, an insulated layer is extruded at the outermost layer, a plurality of aluminum wires are stranded and tightly pressed to form the tile conductor, and a semi-conductive belt is wrapped outside each strand of tile conductor. The segmental conductor-type steel core aluminum stranded wire overhead insulated cable has the advantage of large current-carrying capacity, the problem of a long span between poles can be solved, the main cable usage amount is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a split-conductor type steel-cored aluminum stranded overhead insulated cable. Background technique [0002] The development of new urbanization, the increase of power lines, and the construction of intricate power grids lead to an increase in costs. In view of the new situation, increasing the cross-section of cable conductors and increasing the distance between poles is a solution to reduce costs and increase carrying capacity. indispensable way. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides a split-conductor-type aluminum-steel wire overhead insulated cable, which has the characteristics of large carrying capacity, solves the problem of long spans between poles, reduces the amount of backbone cables, and reduces the costs. [0004] The invention includes a central steel strand layer formed by concentrically tw...
