Abstract
The utility model relates to a copper-cladding-aluminum-core self-locking steel-band armored control cable. The cable is formed by a single conductor core or a plurality of conductor cores through cabling. The cable is characterized in that a copper layer wraps an aluminum core so as to form a conductor; the plurality of conductors are intertwisted so as to form conductor cores; a crosslinking polythene insulation layer wraps an external layer of each conductor core; a wrapping tape layer wraps the insulation layer; an external layer of the wrapping tape layer is a copper strip branch shielding layer; cabling and wrapping are performed on the conductor cores so as to form an outer wrapping tape layer; a filling layer is arranged between a copper strip branch shielding layer and an outer wrapping layer; an outer layer of the outer wrapping tape layer is a copper strip total shielding layer; a polythene inner sheath is extruded outside the copper strip total shielding band layer; an outer layer of the inner sheath is a self-locking steel band armor layer and finally a polythene outer sheath is extruded. The cable of the utility model has the advantages that the cable is suitable for a voltage scope of 450v-1kv; copper resources are saved; production cost is reduced and cable weight is mitigated so that transportation and on-site construction are convenient; tensile performance, impact resistance performance and a bending radius of the cable are increased; good mechanical damage resistance performance is possessed and a good shielding capability is possessed too.
Description
Technical field
The utility model relates to electric wire field, is specifically related to copper-covered aluminum-core self-locking steel tape armouring control cable.
Background technology
Along with economic development, the demand of cable is increasing, and industry competition is fierce, causes the high cost of electric wire.Fine copper is led core cable because copper resource is deficienter, be subject to the impact of international market, and weight is heavier, all more inconvenient at aspects such as transportation and site operations.Fine aluminium is led core and is determined that by self attributes discomfort is fit to do cable conductor.Amid all these factors copper clad aluminum conductor is widely used, and all trades and professions are more and more higher to the requirement of cable at present, beyond the market competitiveness factor on control cables basis more than not only needing to solve, also need the anti-mechanical damage abilities such as higher shielding and better pull resistance, anti-impact force to cater to the needs in market, the tensile strength of copper cash is 220-270mpa, copper-clad aluminum conductor tensile strength is 90-120mpa, and this causes the tension degree of copper-clad aluminum conductor inadequate.Cable industry, in order to increase the tensile property of cable, increases armour at cable, and armour anti-impact force is inadequate at present.
Summary of the invention
The utility model provides a kind of copper-covered aluminum-core self-locking steel tape armouring control cable, be specially adapted to voltage range at 450v-1kv, utilize copper-clad aluminum conductor to possess the conductivity of copper and the little composite attribute of the density of aluminium as conductor simultaneously, adopt double layer screen and self-locking steel band to solve the problems referred to above.
Copper-covered aluminum-core self-locking steel tape armouring control cable, by single, lead core or many and lead core stranding and form, it is characterized in that, copper layer metallized aluminum core forms conductor, core is led in the many stranded formation of conductor, each leads the outer wrapped crosslinked polyetylene insulated layer of core, the outer wrapped one deck belting layer of insulating barrier, and belting layer skin is sub-shield; Leading the outer belting layer of the wrapped formation of core stranding, is packed layer between sub-shield and outer lapping layer, and outer belting layer skin is total screen, always shields belt and extrudes polyethylene inner sheath outward, and inner sheath is outer for self-locking steel-tape armouring layer, finally extrudes outer protective polyethylene cover.
The utility model beneficial effect fruit: being applicable to voltage range is 450v-1kv, utilizes copper-covered aluminum-core to replace fine copper to make cable core, not only saves copper resource, reduces production costs and alleviates cable own wt, is convenient to transportation and site operation; By the stranded great pull resistance that increases cable of copper-covered aluminum-core and carbon fiber; Armouring is self-locking mode, increases pull resistance, impact resistance and the bending radius of cable, has fabulous mechanical bruise resistance, adopts two-phase shielding, has fabulous screening ability.
