Description
Technical field
The present invention relates to a kind of multiple layer combination insulated cable.
Background technology
Cable is typically by several or several groups of wires（Every group at least two）The cable for the similar rope being twisted, every group
Mutually insulated between wire, and be often twisted into around a center, whole outside is surrounded by the coating of high-insulation, and cable needs
With interior energization, the feature of external insulation.
A layer insulating is generally provided with outside the conductor of cable in the prior art, insulating barrier is usually polyvinyl chloride
（PVC）Insulator, the insulating barrier cost of manufacture is high, and heat endurance is bad, and resistance to ag(e)ing is poor, therefore insulating barrier short life, occurs
Easily leaked electricity after breakage, cause security incident, it is therefore necessary to design a kind of cable of good insulation preformance.
The content of the invention
It is usually polyvinyl chloride to solve insulating barrier in the prior art（PVC）Insulator, the insulating barrier cost of manufacture is high, heat
Stability is bad, and resistance to ag(e)ing is poor, therefore insulating barrier short life, occur it is damaged after easily leak electricity, the problem of causing security incident,
The present invention is achieved by the following technical solutions：
A kind of multiple layer combination insulated cable, including：Copper conductor, conductor shield, insulating barrier, metal screen layer, inner sheath,
Bed course, steel wire armor layer, oversheath, copper conductor outside is conductor shield；It is exhausted between conductor shield and metal screen layer
Edge layer；Inner sheath outsourcing bed course；It is steel wire armor layer between bed course and oversheath, wherein insulating barrier is combined insulation layer, by two
Layer brown paper and multi-layer polypropylene platen PPLP compositions, put in order as one layer of brown paper-mono- layer of multilayer PPLP- brown paper.
Preferably, the conductor is copper conductor, is twisted by stranded conductor.
Preferably, the metal screen layer is made up of metal.
Preferably, the inner sheath is PE sheaths.
Preferably, the steel wire armor layer is made up of zinc-coated wire.
Preferably, the oversheath is PVC sheath.
Because a kind of insulating barrier of multiple layer combination insulated cable of the utility model is combined insulation layer, by two layers brown paper and
Multi-layer polypropylene platen PPLP is formed, and is put in order as one layer of brown paper-mono- layer of multilayer PPLP- brown paper, such a to put in order
Good insulating, multilayer PPLP heat endurances are good in addition, ageing-resistant, and the cable is durable in use.
Brief description of the drawings
Fig. 1 is a kind of multiple layer combination insulated cable structural representation of the present invention.
Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
As shown in figure 1, a kind of multiple layer combination insulated cable of the utility model includes copper conductor 1, conductor shield 2, insulation
Layer 3, metal screen layer 4, inner sheath 5, bed course 6, steel wire armor layer 7, oversheath 8, the outside of copper conductor 1 is conductor shield 2；Lead
It is insulating barrier 3 between body screen layer 2 and metal screen layer 4；The outsourcing bed course 6 of inner sheath 5；It is steel wire between bed course 6 and oversheath 8
Armor 7, wherein insulating barrier 3 are combined insulation layer, are made up of, put in order two layers of brown paper and multi-layer polypropylene platen PPLP
For one layer of brown paper-mono- layer of multilayer PPLP- brown paper, wherein, conductor 1 is copper conductor, is twisted by stranded conductor, and it is conductive
Property is more preferable；Metal screen layer 4 is made up of metal, and shield effectiveness is good；Inner sheath 5 is PE sheaths；The steel wire armor layer 7 is by plating
Zinc steel wire forms, wear-resistant, increases the service life of cable；Oversheath 8 is PVC sheath, and resistance to acids and bases is good.
Because a kind of insulating barrier of multiple layer combination insulated cable of the utility model is combined insulation layer, by two layers brown paper and
Multi-layer polypropylene platen PPLP is formed, and is put in order as one layer of brown paper-mono- layer of multilayer PPLP- brown paper, such a to put in order
Good insulating, PPLP heat endurances are good in addition, ageing-resistant, and the cable is durable in use.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：In specification
Its technical scheme described in foregoing embodiments can still be modified, or to which part technical characteristic carry out
Equivalent substitution, and these modifications or replacement, do not make the essence of appropriate technical solution depart from various embodiments of the present invention technical side
The spirit and scope of case.
