Description

The cable metal wire rod of nanometer powder sintered bonds

Technical field

The utility model relates to the cable technology field, relates to or rather a kind of cable metal wire rod of nanometer powder sintered bonds.

Background technology

Cable with metal wire rod comprise copper cash or aluminum steel normally cross section be circular wire rod, the conductive cores of cable is exactly to be made by the metal wire rod spiral winding of many circles, squeezing action by mould, the multiply metal wire rod is extruded distortion, twists cross section processed and be the strand structure processed of the shapes such as fan-shaped, watt shape, circle.Circular metal wire rod strand is built in together, can there be the space in the middle of three adjacent wire rods, because the space is non-conductive, like this in order to reach satisfactory effective conductive area, the actual cross-sectional area of the strand structure processed of metal wire rod tends to greater than effective conductive area, after the metal wire rod chap, the material usage of the outer jacket that the outside needs, armour and packed layer also increases thereupon, causes the cable chap, become heavy, and then the lifting cable cost, improve logistics cost, increased difficulty of construction.In addition, because metal wire rod strand structure processed is to be formed by the mould extruding, the stress that self has expanse, cause each money paid for shares to belong to the larger sheet resistance of existence between the wire rod, so that the part transmission current is not mobile along the axis direction of cable, but along each strand electric wire internal flow that is spiral strand state processed, the current delivery length of equivalence increases, and resistance dissipates and increases; Near the section that cable blocks, loose situation can occur in an end of the opening of metal wire rod strand structure processed under the effect of swelling stress simultaneously.

This shows that above-mentioned existing cable still has many defectives with metal wire rod strand structure processed, and demands urgently being improved.

Because the defective that above-mentioned existing cable exists with metal wire rod strand structure processed, the design people is based on being engaged in this type of product design manufacturing for many years, amassing has abundant practical experience and professional knowledge, positive research and innovation in addition, in the hope of founding a kind of cable metal wire rod of nanometer powder sintered bonds, can improve the general on the market molding structure of existing cable metal wire rod, make it have more competitiveness.Through constantly research, design, and after repeatedly studying sample and improvement, finally create the utility model that has practical value.

Summary of the invention

Technical problem underlying to be solved in the utility model is, overcome the defective that existing cable exists with metal wire rod strand structure processed, and provide a kind of cable metal wire rod of nanometer powder sintered bonds, overcome existing cable and had the space with metal wire rod, there is expansionary stress, resistance loss between each strand electric wire, and loose defective can occur at an open end improves cable with the tightness degree of metal wire rod strand structure processed.

The utility model solves its technical problem underlying and realizes by the following technical solutions.Cable metal wire rod according to the nanometer powder sintered bonds that the utility model proposes, by electric main, the first space electric wire, Second gap electric wire and nanometer powder strand system form, electric main, the cross section of the first space electric wire and Second gap electric wire is rounded, the cross-sectional area of the first space electric wire is one of 1/50th to one percentage of electric main cross-sectional area, the cross-sectional area of Second gap electric wire is that one of two percentages of electric main cross-sectional area are to one of five percentages, the first space electric wire and Second gap electric wire are positioned at the position, space of adjacent three electric mains, nanometer powder is filled the first space electric wire, space between Second gap electric wire and the electric main, by sintering, described nanometer powder is with the first space electric wire, Second gap electric wire and electric main close adhesion.

The cable metal wire rod of nanometer powder sintered bonds described in the utility model, the beneficial effect of its generation is: adopt the position, space of adjacent three electric mains of space wire pair to fill, effectively improved effective conductive area of metal wire rod strand structure processed, the adhesive effect of nanometer powder has reduced the resistance between each strand electric wire, improved the compactness of metal wire rod strand structure processed, so that metal wire rod strand structure processed can be not loose at an open end.
