Abstract

The utility model relates to a carbon-fiber copper-cladding-aluminum-core self-locking steel-band armored power cable. The power cable is formed by a single conductor core or a plurality of conductor cores through cabling. The power cable is characterized in that a copper layer wraps an aluminum core so as to form a conductor; the plurality of conductors are intertwisted with a carbon fiber wire so as to form conductor cores; a crosslinking polythene insulation layer wraps an external layer of each conductor core; the conductor core after cabling extrudes a polythene inner sheath; a filling layer is arranged between the insulation layer and the inner sheath; an external layer of the inner sheath is a self-locking steel-band armored layer and finally a polythene outer sheath layer is extruded. According to the power cable of the utility model, the copper cladding aluminum core is used to replace pure copper and is served as a cable core so that copper resources are saved and production cost is reduced; through intertwisting of the copper cladding aluminum core and a carbon fiber, tensile performance of the cable is greatly increased; the cable armor adopts a steel band self-locking mode so as to increase tensile strength and an impact resistance capability of the cable and increase a bending radius of the cable.

Description

Carbon fiber copper-covered aluminum-core self-locking power cable with flat steel wire armouring

Technical field

The utility model relates to electric wire field, is specifically related to carbon fiber copper-covered aluminum-core self-locking power cable with flat steel wire armouring.

Background technology

Along with the demand to metallic copper of society is increasing, the minimizing of copper resource, causes the price increase of copper.Cable industry copper-covered aluminum-core cable under this background arises at the historic moment.According to the attribute of metal self comparatively speaking, the tension degree of copper cash is 220-270mpa, and the tension degree of copper-clad aluminum conductor is 90-120mpa, and the deficiency that this has just determined copper-covered aluminum-core cable pull resistance has limited the application of copper-covered aluminum-core cable.Power cable is the cable for transmitting and distribute electric energy, needs higher compressive resistance.If use, need better performance under particular surroundings.The tensile strength of carbon fiber, more than 3500Mpa, is 7-9 times of steel.Tensile modulus of elasticity is more than 230Gpa, and higher than steel, and its proportion is 1/4 of steel.Although the metal armouring of common copper clad aluminum power cable has resistance to tension, impact resistance is poor, bending radius is less.

Summary of the invention

The utility model provides carbon fiber copper-covered aluminum-core self-locking power cable with flat steel wire armouring, utilize copper-clad aluminum conductor to possess the conductivity of copper and the little composite attribute of the density of aluminium as conductor simultaneously, when having saved a large amount of copper resource, utilize with carbon fiber twisting and increase copper-covered aluminum-core power cable pull resistance, adopt self-locking steel band to increase the ability of the anti-mechanical damage of cable.

Carbon fiber copper-covered aluminum-core self-locking power cable with flat steel wire armouring, lead core or many and lead core stranding and form by single, it is characterized in that, copper layer metallized aluminum core forms conductor, and many conductors are led core with the stranded formation of carbon fiber line, each outer wrapped crosslinked polyetylene insulated layer of core of leading, after leading core stranding, extrude polyethylene inner sheath, between insulating barrier and inner sheath, be packed layer, inner sheath is outer for self-locking steel-tape armouring layer, finally extrudes outer protective polyethylene jacket layer.

The utility model beneficial effect fruit: utilize copper-covered aluminum-core to replace fine copper to make cable core, save copper resource, reduce production costs; By the stranded great pull resistance that increases cable of copper-covered aluminum-core and carbon fiber, and carbon fiber has creep resisting feature; Cable armouring adopts steel band self-locking mode to strengthen greatly resistance to tension and the impact resistance of cable, increases the bending radius of cable.
