Abstract
The utility model provides a high fire -retardant fire -resistant power cable in oxygen layer that separate belongs to cable technical field. It has been solved current cable and has not been possessed fire -retardant effect, or fire -retardant fire -resistant effect subalternation problem very. This high fire -retardant fire -resistant power cable in oxygen layer that separate, including the conductor, the outside of conductor is wrapped in proper order and is equipped with functional layer and protective layer, the functional layer be conductor shield, insulating layer from inside to outside in proper order, separate oxygen layer and insulation screen, the protective layer be band layer, armor and oversheath from inside to outside in proper order, the utility model discloses structural design is compact, and job stabilization is reliable, has fire prevention advantage such as fire -retardant high temperature resistant.
Description
Technical field
This utility model belongs to field of cable technology, refers in particular to a kind of high fire-retardance oxygen barrier layer fireproof power cable.
Background technology
At present, cable type on market is various, they are applied in all trades and professions, different occasion, but the structure of major part cable still suffers from defective, for instance it is unreasonable that layer of structure designs, and between each layer, structure is compact not, conductor shape is more single, the Rotating fields easily causing cable is easily impaired, and result of use is undesirable, causes that service life is partially short.
Summary of the invention
The purpose of this utility model is to provide a kind of high fire-retardance oxygen barrier layer fireproof power cable, it solves the defect existed in prior art, and layer of structure is reasonable in design, is completely embedded, compact conformation between each layer, and result of use is good.
The purpose of this utility model is achieved in that
High fire-retardance oxygen barrier layer fireproof power cable; including conductor; it is characterized in that: the outside of conductor is wrapped successively and is provided with functional layer and protective layer; described functional layer is followed successively by conductor shield, insulating barrier, oxygen barrier layer and insulation screen from inside to outside, and described protective layer is followed successively by belting layer, armor and oversheath from inside to outside.
In above-mentioned high fire-retardance oxygen barrier layer fireproof power cable, described armor is steel wire armor layer or steel-tape armouring layer, and described steel wire armor layer is: some steel wires are around in the outside of conductor in the shape of a spiral, and wherein helical angle is 5 ~ 30 degree.
In above-mentioned high fire-retardance oxygen barrier layer fireproof power cable, described conductor shield is metal paper tape or semiconductive paper tape.
In above-mentioned high fire-retardance oxygen barrier layer fireproof power cable, described belting layer is non-woven fabrics.
This utility model highlights and useful having the technical effect that compared to existing technology
This utility model layer of structure is reasonable in design, is completely embedded, compact conformation between each layer, and result of use is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
This utility model is further described with specific embodiment below in conjunction with accompanying drawing: referring to Fig. 1,
High fire-retardance oxygen barrier layer fireproof power cable; including conductor 1; the outside of conductor is wrapped successively and is provided with functional layer and protective layer; described functional layer is followed successively by conductor shield 2, insulating barrier 3, oxygen barrier layer 4 and insulation screen 5 from inside to outside, and described protective layer is followed successively by belting layer 6, armor 7 and oversheath 8 from inside to outside.
Described armor is steel wire armor layer or steel-tape armouring layer, and described steel wire armor layer is: some steel wires are around in the outside of conductor in the shape of a spiral, and wherein helical angle is 5 ~ 30 degree.
Described conductor shield is metal paper tape or semiconductive paper tape.
Described belting layer is non-woven fabrics.
Being provided with flame-retardant layer 9 between described oversheath and armor, described flame-retardant layer is fire prevention band.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
