Abstract
A low-smoke zero-halogen flame-retardant copper core crosslinked polyethylene insulation power cable comprises a conductor. The outer portion of the conductor is sequentially wrapped with an insulating layer, a water-blocking belt, a composite belt, an inner sheath, a shielding layer and an outer sheath. First the water-blocking belt and the low-smoke zero-halogen sheaths are adopted to serve as waterproof components, the aluminum plastic composite belt and the soft copper strip double-layer shielding layer serve as anti-electromagnetic interference components, a ratproof ant-proof repellent polyolefin material is added into the inner sheath and the outer sheath, the cable not only has water tightness, but also has ratproof ant-proof functions, and use safety of the cable is enhanced.
Description
Technical field
The present invention relates to a kind of power cable, relate in particular to the crosslinked polyetylene insulated low-smoke non-halogen flame-retardant power cable of a kind of copper core.
Background technology
Now, the pvc sheath that conventional cable uses contains halogen, deposit in use fail safe, problem that reliability is low, secondly, the material that cable uses does not have the function of waterproof, has the poor problem of block-water performance, and, after cable laying, damage because be easily subject to mouse, biting of ant, greatly reduce like this safety in utilization and the useful life of cable.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and the crosslinked polyetylene insulated low-smoke non-halogen flame-retardant power cable of a kind of copper core providing, it can solve low problem of fail safe, reliability, useful life, after can also effectively preventing cable laying, damages because be subject to mouse, biting of ant.
The object of the present invention is achieved like this:
The crosslinked polyetylene insulated low-smoke non-halogen flame-retardant power cable of a kind of copper core, comprises conductor, is enclosed with successively insulating barrier, waterstop, composite band, inner sheath, screen, oversheath outward at conductor.
Described composite band is aluminium-plastic tape.
Described inner sheath and oversheath are low smoke and zero halogen sheath.
The material of described inner sheath and oversheath is the low-smoke halogen-free polyolefin material that contains termite-resistant rodent-resistant repellant composition.
Described screen is armouring screen.
Described screen adopts aluminium-plastic tape to add soft copper band double-layer shielding structure.
The present invention has obtained following technique effect:
First the present invention has adopted waterstop and low smoke and zero halogen sheath as waterproof part, secondly it adopts aluminium-plastic tape and soft copper band double layer screen as anti-electromagnetic interference parts, in it, outer jacket adopts the polyolefine material that has added termite-resistant rodent-resistant repellant composition again, not only make cable possess water preventing ability, and it has the function of termite-resistant rodent-resistant, strengthen the safety in utilization of cable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention.
Embodiment
The crosslinked polyetylene insulated low-smoke non-halogen flame-retardant power cable of copper core, comprises conductor 1 as shown in Figure 1, is enclosed with successively insulating barrier 2, waterstop 3, composite band 4, inner sheath 5, screen 6, oversheath 7 outside conductor 1.Composite band 4 is aluminium-plastic tape.Inner sheath 5 and oversheath 7 are low smoke and zero halogen sheath.The polyolefine material that the material of inner sheath 5 and oversheath 7 contains termite-resistant rodent-resistant repellant composition in forming.Composite band 4 and screen 6 are the double armouring of screen and shielding.Screen adopts aluminium-plastic tape to add the double-layer shielding structure of soft copper band, the armouring effect of holding concurrently of soft copper band.
It is applicable in subway or light rail.
Conductor 1 adopts and meets that the Equations of The Second Kind of GB/T3956-2008 is round presses copper conductor.
Insulating barrier 2 adopts cross-linked polyethylene insulating material, and performance meets the regulation of GB/T12706.1-2008.
Waterstop 3 is extruded by the overlapping wrapped and vertical alclad plastic composite strip of waterstop and low smoke and zero halogen sheath, effectively prevents that moisture from entering insulating barrier, reaches radial water-resisting performance.
The polyolefine material that the material of inner sheath 5 and oversheath 7 contains termite-resistant rodent-resistant composition in forming, jacket thickness is pressed GB/T2952-2008 and is determined.
