Problems solved by technology

[0003] Cable products are usually divided into single-core cables and turnkey three-core cables. Although single-core cables have small outer diameter and large transmission capacity, they require a large space in the power system, cumbersome construction, unbalanced operation, and required bending. The radius is not less than 20 times the outer diameter of the cable; although the turnkey three-core cable has a compact stru

Abstract

The invention relates to a power cable and especially relates to a single-core stranded power cable. The invention discloses a 10 kilovolt (KV) single-core stranded cluster crosslinking polyethylene insulation flame retardation power cable. The single core cable comprises: a conductor wire core, a conductor shielding layer, an insulating layer, an insulation shielding layer a metal shielding layer which is arranged out of the insulation shielding layer, an outer sheath which is arranged out of the metal shielding layer, and at least two single core cables which are formed through stranding. The power cable of the invention has a simple and reasonable structure and is easy to be produced. Flexibility is raised and a bending radius requirement can be reduced. Installation and maintenance are convenient. A transmission capacity is raised. The power cable can be used in important occasions, such as a power plant, a power transmission line and the like.

Description

technical field [0001] The invention relates to a power cable, in particular to a single-core twisted power cable. Background technique [0002] There are many power material products used in power transmission and distribution systems. As the main product of urban power construction, power cables, with the continuous development of cities and the continuous increase of power facilities, the construction space is becoming tighter. Laying lines, which put forward new requirements for the structure of cable products, cable products with compact structure, large transmission capacity, small bending radius, light weight, and convenient construction and maintenance have attracted widespread attention. [0003] Cable products are usually divided into single-core cables and turnkey three-core cables. Although single-core cables have small outer diameter and large transmission capacity, they require a large space in the power system, cumbersome construction, unbalanced operation, an...
