Abstract
The utility model discloses a composite flat cable for a harbor. The composite flat cable for the harbor comprises a control cable core and a main cable core, wherein an inner-layer polyester belt and a nitrile polyvinyl chloride compound insulating layer sequentially wrap outside a conductor to form insulated control cable cores; a nitrile polyvinyl chloride compound sheath, a middle-layer polyester belt, a combined braid layer composed of a copper wire and a polyamide fiber, and an outer-layer polyester belt sequentially wrap outside the three insulated control cable cores which are twisted to form the control cable core; the main cable core is formed by three main insulated cable cores arranged in parallel; each main insulated cable core comprises an inner polyester belt, the nitrile polyvinyl chloride compound insulating layer, the middle-layer polyester belt, the combined braid layer composed of the copper wire and the polyamide fiber, and the outer-layer polyester belt, which sequentially wrap outside the conductor; and the control cable core and the main insulated cable cores are arranged in parallel and are subjected to press wrapping of the nitrile polyvinyl chloride compound sheath. The cable is integrated with control and power transmission copper wires, solves the problems of electricity utilization, transmission control and signal measurement of equipment, not only reserves the characteristics of a common control cable, but also can meet related standards of a low-voltage power transmission cable.
Description
Technical field
The utility model relates to a kind of power cable, and particularly the harbour composite flat cable, belong to technical field of electric wires and cables.
Background technology
economic development along with China, China coast and interior river valley have been built up many major ports, and cable properties there is the requirement of himself with the supporting various power constructions in harbour, natural conditions according to the building site, harbour, harbour construction power transmission and distribution power cable, the interim distribution cable in building site and light conduits, telecommunication cable, harbour machinery with cable etc. in running because being subject to frequent bending, stretch, the multiple mechanical stress effects such as cable deadweight, easily cause the conductor core that breaks, the phenomenons such as sheath breakage, cause equipment to shut down, had a strong impact on user's normal use, cause very large economic loss to the user.
The utility model content
Goal of the invention of the present utility model is to provide a kind of low temperature resistant, tension, softness, aging-resistant harbour composite flat cable.This cable integrates control, transmission of electricity copper cash, solves equipment electricity consumption, transfer control, measuring-signal problem, has not only kept the characteristic of general control cable, and can also satisfy the relevant criterion of low voltage power transmission cable.
The purpose of this utility model is achieved through the following technical solutions:
The harbour composite flat cable, comprise and control core and master core, its design feature is, coat successively internal layer polyester belt and butyronitrile polyvinyl chloride composite insulating barrier outward by conductor and consist of insulation and control core, after three insulated pilot wire cores are stranded, its outer butyronitrile polyvinyl chloride composite sheath, middle level polyester belt, copper wire, nylon fibre combined knitting layer, outer polyester belt of coating successively consists of and controls cable core; Described main line cable core is arranged in parallel by three main insulation cores and forms, and in described main insulation core coats successively by conductor is outer, polyester belt, butyronitrile polyvinyl chloride composite insulating barrier, middle level polyester belt, copper wire, the combined knitting layer of nylon fibre, outer polyester belt consist of; Described control cable core and main insulation core are arranged in parallel and extrude butyronitrile polyvinyl chloride composite sheath.
The utility model design feature also is:
Described conductor forms by soft copper is stranded, and stranded conductor center arranges the reinforcing element of nylon fibre material.
Metal, opposite direction identical with the nylon fibre number of spindles in described copper wire, nylon fibre combined knitting layer.
Described control cable core is consistent with main insulation core external diameter.
Advantage of the present utility model is mainly reflected in:
1, the utility model reaches stranded insulation and controls the braid that the core peripheral hardware has copper wire and nylon fibre combining structure to consist of outside the main insulation core, and metal is identical with the nylon fibre number of spindles, opposite direction; The proof copper-wire braided layer can double as ground wire, and for earthy, nylon fibre can improve the tensile property of cable, and does not affect the bending property of cable because of the braiding copper wire.
2, it is consistent with main insulation core external diameter that the utility model is controlled cable core, increased the stability of whole cable structure.
3, the utility model has increased the control core in the construction of cable, integrates control, transmission of electricity copper cash.
4, the utility model conductor forms by soft copper is stranded, and stranded conductor center arranges the reinforcing element of nylon fibre material; Can improve the tensile property of conductor, adopt less lay ratio stranded when conductor is stranded simultaneously, lay ratio is 12～14 times, and (single line rotates a circle the distance of advancing twisting pitch around the twisted wire axis, pitch is lay ratio with the ratio of conductor diameter), can improve bending property and the softness of cable.
Description of drawings
Fig. 1 is the utility model construction of cable schematic diagram.
Number in the figure: 1 conductor, 2 internal layer polyester belts, 3 butyronitrile polyvinyl chloride composite insulating barriers, 4 middle level polyester belts, 5 copper wires, nylon fibre braid, 6 outer polyester belts, 7 butyronitrile polyvinyl chloride composite sheaths, 8 butyronitrile polyvinyl chloride composite oversheaths.
Technical solutions of the utility model are described further by embodiment below in conjunction with accompanying drawing.
