Abstract
A high-strength cable for a scraper is characterized in that a copper wire (2) is spirally arranged on the periphery of a steel wire rope (1) to form a conductor, and an ethylene-propylene insulating layer (3) is extruded outside the conductor to form a conductor wire core. The ground wire conductor copper wire (4) is externally extruded with a ground wire insulating layer (5) to form a ground wire core. After the three conductor wire cores and the ground wire core are combined, a non-woven fabric wrapping layer (6) and a chlorinated polyethylene outer sheath (8) are extruded and wrapped on the periphery of the ground wire core. In the cable cross-section, the planar area of the ground wire core is 1/10 to 1/20 of the planar area of the conductor core. The utility model discloses having added the wire rope structure in the conductor sinle silk, having twined in wire rope's periphery as the copper wire of conductor, and single copper wire diameter is not more than 0.41mm, has consequently increased the bulk strength and the breaking force of cable for the cable is in removing the use, and the atress is even, should not warp, need not break, has increased the breaking force, has prolonged the life of cable.
Description
Technical Field
The utility model relates to the technical field of cables, a high strength cable for scraper is provided very much.
Background
When the cable for the scraper is used back and forth, the cable is easily broken and deformed due to uneven stress, normal use of machinery is affected, and even potential safety hazards are caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high tensile, high strength's cable for scraper.
The utility model particularly provides a high strength cable for scraper, 1 peripheral spiral of wire rope set up copper wire 2 and form the conductor, and 3 formation conductor sinle silks of crowded package EP N insulating layer outside the conductor.
The copper wire 4 of the ground wire conductor is extruded outside the ground wire insulating layer 5 to form a ground wire core.
After the three conductor wire cores and the ground wire core are combined, a non-woven fabric wrapping layer 6 and a chlorinated polyethylene outer sheath 8 are extruded on the periphery of the ground wire core.
Between the conductor sinle silk, between conductor sinle silk and the ground wire sinle silk, conductor sinle silk and non-woven fabrics are around setting up packing 7 between the covering, ground wire sinle silk and non-woven fabrics are around the covering.
The ground wire core is arranged between the wire core and the non-woven fabric wrapping layer.
In the cross section of the conductor, the plane area of the steel wire rope 1 is 1/20-1/40 of the whole plane area of the conductor wire core.
In the cable cross-section, the planar area of the ground wire core is 1/10 to 1/20 of the planar area of the conductor core.
The utility model discloses having added the wire rope structure in the conductor sinle silk, having twined in wire rope's periphery as the copper wire of conductor, and single copper wire diameter is not more than 0.41mm, has consequently increased the bulk strength and the breaking force of cable for the cable is removing in the use, and the atress is even, should not warp, need not break, has increased the breaking force, has prolonged the life of cable.
Other indexes are in accordance with the 5 th conductor regulation in GB/T3956-2008.

Detailed Description
Example 1
A high-strength cable for a scraper is characterized in that a copper wire 2 is spirally arranged on the periphery of a steel wire rope 1 to form a conductor, and an ethylene-propylene insulating layer 3 is extruded outside the conductor to form a conductor wire core.
The copper wire 4 of the ground wire conductor is extruded outside the ground wire insulating layer 5 to form a ground wire core.
After the three conductor wire cores and the ground wire core are combined, a non-woven fabric wrapping layer 6 and a chlorinated polyethylene outer sheath 8 are extruded on the periphery of the ground wire core.
Between the conductor sinle silk, between conductor sinle silk and the ground wire sinle silk, conductor sinle silk and non-woven fabrics are around setting up packing 7 between the covering, ground wire sinle silk and non-woven fabrics are around the covering.
The ground wire core is arranged between the wire core and the non-woven fabric wrapping layer.
In the cross section of the conductor, the plane area of the steel wire rope 1 is 1/20-1/40 of the whole plane area of the conductor wire core.
In the cable cross-section, the planar area of the ground wire core is 1/10 to 1/20 of the planar area of the conductor core.
The steel wire rope structure is added in the conductor wire core, the copper wire serving as the conductor is wound on the periphery of the steel wire rope, the diameter of the single copper wire is not larger than 0.41mm, and therefore the overall strength and the breaking force of the cable are increased, the cable is uniform in stress and does not deform or break in the moving use process, the breaking force is increased, and the service life of the cable is prolonged.
Other indexes of the embodiment conform to the 5 th conductor regulation in GB/T3956-2008.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
Moreover, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
