Abstract
The utility model discloses a high-strength anti-theft power cable including a plurality of alloy conductors. The cross sections of the alloy conductors are polygons. The alloy conductors are provided with reinforcing cores composed of high-carbon fiber strands respectively. The conductors are wrapped with silicon rubber insulating layers respectively. The alloy conductors wrapped with the silicon rubber insulating layers are twisted with each other, so that a cable core is formed. A coiling layer formed by coiling a fire-proof mica tape in an overlapped manner and an inner sheath are arranged outside the cable core successively. An anti-theft layer is arranged outside the inner sheath. An inner layer of the anti-theft layer is formed by adopting high-carbon zinc-coated wires for weaving into a net shape, a middle layer of the anti-theft layer is formed by coiling a steel tape and an outer layer is formed by twisting steel wires in a spiral manner. The distance between the steel wires of the outer layer is not larger than 2.5 times of the diameter of the steel wires. An outer sheath is arranged outside the anti-theft layer. According to the utility model, the material cost is reduced by adopting the alloy conductors, the inner part of the high-strength anti-theft power cable is prevented from damaging by adopting the reasonable structural design and the mechanical strength of the high-strength anti-theft power cable is also improved, so that the stability of the high-strength anti-theft power cable in long-distance power transmission.
Description
Technical field
The utility model relates to power cable field, specifically a kind of high-strength anti-theft type power cable.
Background technology
As everyone knows, on 80% cost of power cable, all on copper conductor, along with the continuous increase in cable conductor cross section, the cost that copper conductor occupies also constantly increases.Constantly soaring along with the copper valency stolen and cuts power cable and strip copper conductor and make profit and become some offender's appurtenance means.
Especially in the area of public security weak, steal that to cut the cable phenomenon particularly outstanding.The interruption impact of power cable causes large-area power-cuts, plant downtime, and the loss that causes can't be estimated, and it is long to change the cable cycle, and expense is large, consumes a large amount of manpower and materials, and this just has higher requirement to the theftproof performance of cable.
In addition, cable is in length is carried apart from electric power, and conventional electric power cable machinery intensity does not reach requirement, so the electric power transfer of cable can not get permanent guarantee.
The utility model content
Make up the defective of prior art, the purpose of this utility model is to provide a kind of high-strength anti-theft type power cable, improves on the basis of common power cable, improves anti-theft and the mechanical strength of cable, has effectively guaranteed the normal operation of cable.
The technical solution of the utility model is as follows:
high-strength anti-theft type power cable, it is characterized in that: include several alloy conductors, several alloy conductors cross section is polygon, be respectively equipped with the strengthening core that high carbon fibre tow strand consists of in several alloy conductors, every conductor is enclosed with respectively silicone rubber insulation layer outward, the mutual stranded bunchy of several alloy conductors of parcel silicone rubber insulation layer consists of cable core, cable core is provided with the lapping layer of the overlapping wrapped formation of fire-resistant isinglass belt outward successively, inner restrictive coating, described inner restrictive coating is provided with theft-proof layer outward, theft-proof layer first adopts the high-carbon zinc-coated wire to be woven into netted formation internal layer, then adopt the wrapped formation of steel band middle level, steel wire spiral is wound around and consists of skin, spacing between outer field winding is not more than 2.5 times of steel wire diameter, described theft-proof layer is outer is formed with external sheath layer by extrusion molding.
Described high-strength anti-theft type power cable is characterized in that: the internal layer high-carbon zinc-coated wire count of described theft-proof layer is not less than 85%, and the steel band wrapped rate of putting up in middle level is not less than 35%.
The beneficial effects of the utility model:
The utility model is adopting alloy conductor to reduce material cost, be provided with theft-proof layer between the employing tension core of cable and interior external sheath layer, can effectively reduce cable inside injury-free, also strengthened the mechanical strength of cable, in addition, cable has ensured the stability of cable electric power transfer in big-length, remote distance power are carried, extended the useful life of cable.
