Abstract
The utility model discloses a scalloped multi-core power cable comprising multiple tin-coated copper conductors. The multiple tin-coated copper conductors are divided into multiple groups. The multiple tin-coated copper conductors in each group are arranged in a scalloped structure in order to form a scalloped wire core. Each scalloped wire core is wrapped in a scalloped insulating layer and a scalloped inner sheath layer. The scalloped inner sheath layers of the multiple scalloped wire cores are wrapped in an inner liner layer. The multiple scalloped wire cores in the inner liner layer are arranged symmetrically and form an annular structure. The inner liner layer is successively wrapped in a metal shielding layer, a crosslinked polyethylene insulating layer, and a chlorinated polyethylene outer sheath layer. Multiple steel wires are disposed in the crosslinked polyethylene insulating layer and are arranged in a circle to wrap round the metal shielding layer. The scalloped multi-core power cable has an ingeniously-improved structure. The cable wire cores are designed in multiple scalloped structures and the scalloped wire cores are arranged symmetrically in order to form an annular structure. Therefore, strong compactness is achieved and thus the integral mechanical strength is increased.
Description
Technical field
The utility model relates to a kind of cable, mainly is a kind of fan-shaped multi-core power cable.
Background technology
Existing general cable core all is a circular configuration, is made of round-shapedly a plurality of conductor arrangement, and when a plurality of circular core, structural compactness was not strong between it was adjacent, had influenced the overall construction intensity of cable; Power cable is also mostly in actual use is to cause because be mechanically damaged damaging, thereby needs to strengthen the mechanical strength of whole cable.
The utility model content
Technical problem to be solved in the utility model provides a kind of fan-shaped multi-core power cable, its architecture advances is ingenious, cable core is designed to a plurality of sector structures, and fan-shaped core symmetric arrangement forms loop configuration makes compact strong, thereby has improved whole anti-mechanical strength.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of fan-shaped multi-core power cable, include a plurality of tin-coated copper conductors, it is characterized in that: described a plurality of tin-coated copper conductors are divided into many groups and arrange, a plurality of tin-coated copper conductors in every group are arranged according to sector structure and are formed fan-shaped core, each fan-shaped core is coated with fan-shaped insulating barrier and fan-shaped inner restrictive coating outward respectively, the fan-shaped inner restrictive coating of described a plurality of fan-shaped cores is coated with inner covering outward jointly, a plurality of fan-shaped core symmetric arrangement in the described inner covering forms loop configuration, and described inner covering is coated with metal screen layer outward successively, crosslinked polyetylene insulated layer and haloflex external sheath layer.
Be provided with a plurality of steel wire ropes in described crosslinked polyetylene insulated layer, a plurality of steel wire ropes are arranged a circle and are wrapped in outside the metal screen layer.
In the utility model outside each fan-shaped core respectively coated insulation layer, inner restrictive coating, then integral coating metal screen layer, crosslinked polyetylene insulated layer and haloflex external sheath layer again, the insulation fire resistance is better.
Be provided with steel wire rope in the utility model cable, improved the mechanical strength of cable.
The utility model has the advantages that:
The utility model architecture advances is ingenious, and cable core is designed to a plurality of sector structures, and fan-shaped core symmetric arrangement forms loop configuration makes compact strong, thereby has improved whole anti-mechanical strength.
