Abstract
The invention discloses a waterproof low-voltage cable. The cable comprises conductors, filling petroleum jelly, an inner insulation layer, a warping belt, a shielding layer, an outer insulation layer, tensile wires, a water resisting layer and an outer sheath. The filling petroleum jelly is arranged among the conductors which are wrapped by the inner insulation layer. The warping layer, the shielding layer, the outer insulation layer, the water resisting layer and the outer sheath are successively arranged outside the inner insulation layer. The tensile wires which are twisted in the certain direction are arranged in the outer insulation layer. Each conductor is formed by twisting multiple single core wires. The twisting direction of the single core wires is the same as that of the tensile wires. According to the invention, by arranging the petroleum jelly and the shielding layer outside the conductors, the cable has well shielding and waterproof functions; signal interference during long-term use is reduced; tensile fibers or steel wires used as enforcement wires are arranged in the outer insulation layer, so tensile performance of the cable is improved; by adopting twisting in the anti-clockwise direction, the cable is provided with special bending performance; by arranging the waterproof layer, water is further prevented; and the cable is highly practical.
Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of waterproof low-voltage cable.
Background technology
Existing waterproof low-voltage cable refers to that the cable (comprising) of below 0.6/1KV is waterproof low-voltage cable, and this cable is relatively common, and specification is more, the most conventional, but existing waterproof low-voltage cable structure is complicated, unstable properties, life-span is short, and water resistance is bad, it is impossible to meet use demand.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, it is an object of the invention to provide a kind of waterproof low-voltage cable, and to make it have preferable service behaviour, water resistance is good, meets use demand.
Technical scheme: in order to realize foregoing invention purpose, the technical solution used in the present invention is:
A kind of waterproof low-voltage cable, including conductor, filled stone ointment, inner insulating layer, twining package tape, screen layer, external insulation layer, tensile cord, water blocking layer and oversheath；Between described conductor, set filled stone ointment, and wrapped up by inner insulating layer；Twining package tape, screen layer, external insulation layer, water blocking layer and oversheath is set successively outside inner insulating layer；The tensile cord that a plurality of one-tenth certain orientation is stranded is set in external insulation layer；Wherein, conductor is formed by a plurality of single-core line is stranded, and direction of lay is identical with tensile cord direction of lay.
The diameter of described tensile cord is less than the thickness of external insulation layer.
Described a plurality of tensile cord is spaced apart from each other to be located in external insulation layer.
Described screen layer is copper mesh braid over braid.
Described tensile cord is traction-resistant fibre or steel wire.
Described single-core line is red copper conductor or brass conductor.
Beneficial effect: compared with prior art, the waterproof low-voltage cable of the present invention, use at conductor peripheral hardware filled stone ointment and screen layer, there is good function of shielding and water resistance, reduce the signal disturbing in life-time service, in external insulation layer, set traction-resistant fibre simultaneously or steel wire uses as line feeder, add the pull resistance of product, employing is the most stranded makes product have special bending property, arranges water blocking layer and further blocks water, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of waterproof low-voltage cable.
Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings.
As it is shown in figure 1, waterproof low-voltage cable, including conductor 1, filled stone ointment 2, inner insulating layer 3, twining package tape 4, screen layer 5, external insulation layer 6, tensile cord 7, water blocking layer 8 and oversheath 9；Between conductor 1, set filled stone ointment 2, and wrapped up by inner insulating layer 3；Twining package tape 4, screen layer 5, external insulation layer 6, water blocking layer 8 and oversheath 9 is set successively outside inner insulating layer 3；The tensile cord 7 that a plurality of one-tenth certain orientation is stranded is set in external insulation layer 6；Wherein, conductor 1 is formed by a plurality of single-core line is stranded, and direction of lay is identical with tensile cord 7 direction of lay.
The diameter of tensile cord 7 is less than the thickness of external insulation layer 6, and a plurality of tensile cord 7 is spaced apart from each other to be located in external insulation layer 6.Screen layer 5 is copper mesh braid over braid.Tensile cord 7 is traction-resistant fibre or steel wire.Single-core line is red copper conductor or brass conductor.
The waterproof low-voltage cable of the present invention, use at conductor peripheral hardware filled stone ointment and screen layer, there is good function of shielding and water resistance, reduce the signal disturbing in life-time service, setting traction-resistant fibre in external insulation layer simultaneously or steel wire uses as line feeder, add the pull resistance of product, employing is the most stranded makes product have special bending property, arrange water blocking layer further to block water, there is good practicality.
