Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 Shown is a water-blocking super-large cross-section hollow segmented conductor, the center of which is a hollow layer or a filled water-blocking layer 1; a single-layer conductor single-wire layer 2 is arranged outside the hollow layer or filled water-blocking layer 1; A plurality of corrugated conductor strands 3 are arranged outside the single wire layer, and a corrugated water-blocking layer 4 is arranged outside each corrugated-shaped conductor strand; water-blocking filling strips 5 are arranged in the gaps between the corrugated-shaped water-blocking layers , a water-blocking layer 6 is provided outside a plurality of corrugated conductor strands.

[0019] The conductor single-wire layer is composed of a plurality of "Z"-shaped conductor single-wires. The "Z"-shaped conductor single-wire is a self-supporting structure with a stable structure. ...

Abstract

The invention discloses a water-blocking super-large section hollow split conductor. The center of the conductor is provided with a hollow layer or a filled water-blocking layer; a single conductor single-line layer is arranged outside the hollow layer or the filled water-blocking layer; a plurality of corrugated conductor blocks are arranged outside the conductor single-line layer; a corrugated water-blocking layer is arranged outside each corrugated conductor block; a gap among the corrugated water-blocking layers is provided with a water-blocking filling strip; and a water-blocking layer is arranged outside the plurality of corrugated conductor blocks. The water-blocking super-large section hollow split conductor has the characteristics of being low in characteristic requirements on a tooling mold and equipment, stable in structure, low in skin effect, high in carrying capacity and good in water-blocking property, corrosion resistance and oxidation resistance, and the difficulty of the production technology is reduced.

Description

technical field [0001] The invention relates to the field of cable conductors, in particular to a water-blocking super-large cross-section hollow segmented conductor. Background technique [0002] With the rapid growth of China's economy and the further acceleration of industrialization and urbanization, the requirements for the construction of infrastructure such as urban power grids are increasing. Cities in developed regions and provincial capitals have required the use of underground power cables to transmit electric energy in urban centers. At the same time, electricity is the premise and foundation of the development of the national economy. With the rapid development of the national economy, the demand for electricity has increased sharply, the capacity of the grid has increased sharply, and the power of motors has increased. ) transmission direction development. In order to increase the carrying capacity of the cable, the method of increasing the cross section of th...
