Description
Technical field
This utility model relates to field of cables, is specifically related to a kind of fire-proof and water-proof high temperature resistant electric power electricity
Cable.
Background technology
Power cable is a kind of cable for transmitting and distribute electric energy, along with the progress of society,
Power cable is widely used, and it provides required supply of electric power for daily life.By
More severe in the applied environment of power cable, need to possess superpower twisting resistance, fire-retardant, anti-
The features such as water, particularly anti-flammability, the sheath material of general cable is easily ignited, if fire-retardant
Property poor, these materials once burn, and produce a large amount of dense smoke containing extremely toxic substance, right
Environment, human body very harmful.
Utility model content
For defect present in prior art, the purpose of this utility model is to provide one anti-
Fire waterproof heat-resisting power cable, has good fire-retardant, waterproof and resistance to elevated temperatures.
For reaching object above, this utility model adopts the technical scheme that: include cable core with
And described cable core wrap up the most successively insulating barrier, waterproof layer, sheath, armor, resistance
Combustion layer and outer jacket；Described waterproof layer is waterstop；Described flame-retardant layer is low-smoke bittern-free highly fire-proof
Band；The material of described outer jacket is low smoke halogen-free flame-retardant polyolefin.
On the basis of technique scheme, described cable core is metallic conductor.
On the basis of technique scheme, the material of described insulating barrier is crosslinked polyethylene.
On the basis of technique scheme, the material of described sheath is low smoke and zero halogen polyene
Hydrocarbon.
On the basis of technique scheme, described armor is the bimetallic strip of spiral.
Compared with prior art, the utility model has the advantage of: high by low smoke and zero halogen on cable
The flame-retardant layer that inhibiting tape is made considerably increases the fire prevention of power cable, resistance to elevated temperatures, simultaneously
The waterproof layer being made up of waterstop improves the water resistance of cable, and bimetallic strip spiral makes
Armor also drastically increase the twisting resistance performance of cable.
Accompanying drawing explanation
Fig. 1 is the horizontal tangent plane of a kind of fire-proof and water-proof high-temperature-resistant power cable of the present utility model
Figure；
In figure: 1-cable core, 2-insulating barrier, 3-waterproof layer, 4-sheath, 5-armor,
6-flame-retardant layer, 7-outer jacket.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Figure 1, this utility model provides a kind of fire-proof and water-proof high-temperature-resistant power cable,
The insulating barrier 2 that outwards wraps up successively including cable core 1 and cable core 1, waterproof layer 3, interior
Sheath 4, armor 5, flame-retardant layer 6 and outer jacket 7.
Cable core 1 is the metallic conductor that multiple conducting wires is stranded, and insulating barrier 2 uses crosslinking poly-
Ethylene extrudes and forms.In order to improve the water resistance of cable, outside insulating barrier 2, use waterstop
Wrapped form waterproof layer 3.Sheath 4 and outer jacket 7 all use low-smoke halogen-free polyolefin sheath
Material extrudes and forms.In order to improve twisting resistance and the crashworthiness of cable, in the outer employing of sheath 4
Bimetallic strip spiral wrapped composition armor 5.In order to solve conventional power cable because of fire-retardant, anti-
Fire resistance to elevated temperatures is not enough and causes potential safety hazard, at the outer wrapped low-smoke bittern-free highly of armor 5
Combustion band, constitutes flame-retardant layer 6.
This utility model is not only limited to above-mentioned preferred forms, and anyone is at this utility model
Enlightenment under all can draw other various forms of products, no matter but in its shape or structure make
Any change, every have same or like with this utility model as technical scheme, all at it
Within protection domain.
