Abstract
The utility model discloses a cable comprising a conductor wire core, an insulating layer extruded on the surface of the conductor wire core, fillers, a wrapping strip and an outer sheath, wherein the wrapping strip is wound outside the conductor wire core wrapped with the insulating layer; the fillers are arranged in a space between the wrapping strip and the conductor wire core wrapped with the insulating layer; the outer sheath is positioned at the outer layer of the wrapping strip; the floating cable further comprises a foaming inner protection layer which is filled between the wrapping strip and the outer sheath, and the entire density is less than 1. The cable has light weight and good flexibility, and can meet the requirement of frequent reeling and unreeling.
Description
Technical field
The utility model belongs to electrical apparatus electric power transmission field under water, specifically, relates to a kind of buoyant cable.
Background technology
Along with the progress of science and the development of technology, movable electrical appliances kind and purposes are more and more under water, the kind of the electric power connecting line supporting with it is on the increase, performance requirement also improves constantly, traditional electric wire product proportion is bigger, can not float in the water, and flexibility is poor, be easy to damage in cyclic bending and frequent moving, the life-span is shorter.
Summary of the invention
The purpose of this utility model be to provide a kind of in light weight, have improved flexibility and can satisfy the buoyant cable of frequent folding and unfolding.
The utility model realizes that the technical scheme of above-mentioned purpose is, a kind of cable, integral body comprises conductor wire core, is extruded in the insulating barrier on conductor wire core surface, filling, band and oversheath, described band is wrapped in outside the conductor wire core that is coated with insulating barrier, described band and be coated with in the space between the conductor wire core of insulating barrier and have filling, described oversheath is positioned at the band skin, its improvement is: also comprise the foaming sheath, described foaming sheath is filled between band and the oversheath, and global density is less than 1.
The density of described foaming sheath is 0.45g/cm
2About.
The thickness of described foaming sheath is 2 ~ 6mm.
Described conductor wire core is single or many stranded annealed copper conductors or aluminum or aluminum alloy conductor, and its cross section is 1.5mm
2To 25mm
2
Described conductor wire core core number is 2 core to 5 cores.
The described filler that is filled to the chemical blowing macromolecular material.
Described insulating barrier and oversheath are polymer material layer.
The beneficial effects of the utility model are: owing to increased the foaming sheath, density and thickness by control foaming sheath, reducing cable density makes the global density of cable less than 1, the problem that makes cable float on the energy water surface, be convenient to safeguard, have good flexibility, solve frequent folding and unfolding, be applicable to operation in the ponds such as waterworks, swimming pool, the utility model is simple in structure, is convenient to processing and manufacturing and guarantees original mechanical-physical of cable insulation jacket and electric property.
Description of drawings
