Abstract
The invention discloses a cable with high current-carrying capacity. The cable provided by the invention comprises more than one conductor and a sheath (5), wherein the more than one conductor is enamel-cover stranded conductor (1); and an insulating layer (2) is arranged on the surface of the more than one enamel-cover stranded conductor (1) and covers the surface. By adopting the technical scheme, under the condition that the cross-sectional area of the conductors is not increased, the surface area of the conductors is increased; and the conductors are decomposed into a plurality of independent parts and each independent part of the conductors has an insulation system, thus increasing the surface area of the conductors actually, reducing skin effects, improving the current-carrying capacity, keeping the material consumption unchanged, and being easy to realize technically.
Description
Technical field
The invention belongs to the technical field of power cable structure, specifically, the present invention relates to a kind of big ampacity cable.
Background technology
Along with high speed development of national economy, electricity needs is increasing, and the ability of cable transmission electric energy is had higher requirement, and need carry more electric energy with less cross section.But traditional cable is subjected to the influence of conductor kelvin effect, and ampacity is limited, and the kelvin effect of cable is exactly that electric energy just transmits at conductive surface.Generally speaking, need improve current capacity by increasing the ampacity that cross-sectional area of conductor improves cable.
Increase the cross section of conductor, just need to increase the use amount of conductor material, material cost increases; Simultaneously, the increase of cross-sectional area of conductor, materials such as insulation, sheath also increase thereupon.And the outside diameter of cable also increases thereupon, and this just needs the bigger space of laying.So this has not only increased the consumption of resource, the difficulty that has also increased design and laid.
Summary of the invention
The present invention is to provide the technical scheme of big ampacity cable, its objective is the ampacity that improves cable, realize the raising of cable transmission electric energy ability.
To achieve these goals, the technical scheme taked of the present invention is:
Big ampacity cable provided by the present invention comprises conductor, sheath, and described conductor is the enamel-cover stranded conductor, and in described big ampacity cable, the quantity of described enamel-cover stranded conductor is more than one, and its surface is provided with insulating barrier it is wrapped up.
Described enamel-cover stranded conductor constitutes by many single lines are stranded, is equipped with the insulating varnish coating layer on the surface of every single line.
Space between the described enamel-cover stranded conductor is provided with gasket for packing.
In described sheath, be provided with lapping layer, described lapping layer is with all enamel-cover stranded conductors and the wrapped parcel of gasket for packing in the described big ampacity cable.
Described sheath is for extruding jacket structure.
The present invention adopts technique scheme, under the condition that does not increase conductor cross sectional area, it is long-pending to have increased surface of conductors, and conductor is resolved into some parts, and every part all independently exists, every segment conductor has insulation system outward, it is long-pending so just in fact to have increased surface of conductors, has reduced the existence of kelvin effect, has improved the ampacity of cable, and the consumption of material does not increase, and also is easy on the technology realize.
Description of drawings
Below the expressed content of the accompanying drawing of this specification and the mark among the figure are made brief description:
Fig. 1 is structural representation of the present invention.
Be labeled as among the figure:
1, enamel-cover stranded conductor, 2, insulating barrier, 3, gasket for packing, 4, lapping layer, 5, sheath.
Embodiment
Contrast accompanying drawing below, the description by to embodiment is described in further detail the specific embodiment of the present invention, to help those skilled in the art inventive concept of the present invention, technical scheme is had more complete, accurate and deep understanding.
The of the present invention structure expressed as Fig. 1 is a kind of big ampacity cable, comprises conductor, sheath 5.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realize improving the ampacity of cable, improve the goal of the invention of cable transmission electric energy ability, the technical scheme that the present invention takes is:
As shown in Figure 1, big ampacity cable provided by the present invention, described conductor is enamel-cover stranded conductor 1, and in described big ampacity cable, the quantity of described enamel-cover stranded conductor 1 is more than one, and its surface is provided with insulating barrier 2 with its parcel.
The kelvin effect of cable is exactly that electric energy just transmits at conductive surface, and surface of conductors is long-pending just can to reduce kelvin effect as long as increase.Under the condition that does not increase conductor cross sectional area, long-pending in order to increase surface of conductors, conductor is resolved into some parts, every part all independently exists, every segment conductor has insulation to exist outward, it is long-pending so just in fact to have increased surface of conductors, has reduced kelvin effect, has improved the ampacity of cable.
The present invention is exactly under the prerequisite that does not increase cross-sectional area of conductor, by the change of conductor structure, improves the ampacity of cable, realizes the raising of cable transmission electric energy ability.
This scheme economical with materials, simple for process, be convenient to realize.
Described enamel-cover stranded conductor 1 constitutes by many single lines are stranded, is equipped with the insulating varnish coating layer on the surface of every single line.Make the surface of each single line become the carrier of electric current, increase the amount of damming.
Space between the described enamel-cover stranded conductor 1 is provided with gasket for packing 3.Adopt the structure of gasket for packing 3 to carry out the space filling, make cable rounding, full, be suitable for cable laying operation and increase pull resistance.
In described sheath 5, be provided with lapping layer 4, described lapping layer 4 is with all enamel-cover stranded conductors 1 and gasket for packing 3 wrapped parcels in the described big ampacity cable.
Described sheath 5 is for extruding jacket structure.
The conductor of cable adopts the 2nd or 5 class copper conductors, selects the conductor of certain specification and the radical of definite single line for use according to GB/T3956.According to above-mentioned requirements copper cash is drawn into required specification, wire drawing is carried out at wire drawing machine, and conductor is carried out annealing in process, and annealing back resistance should reach standard, and the single line surface should smooth, no greasy dirt, cut etc.
According to the concrete condition of conductor, select normal serviceability temperature suitable, that meet the cable design requirement, each monofilament is carried out enamel-cover, exactly insulating varnish is coated on conductive surface.
The thread reaming machine that adopt to be fit to, will meet process stipulation at the speed of twisted wire, the rotating speed of traction.The enamel-cover monofilament is twisted together, form new stranded conductor, namely the enamel-cover stranded conductor 1.
According to the requirement of product standard, outside enamel-cover stranded conductor 1, select suitable material for use, extruded insulation, stranding and extrude sheath 5.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
