Description
Technical field
The utility model is related to a kind of cable, specifically a kind of extruded insulation fireproof power cable.
Background technology
Cable is typically the conductor thread core for the similar cord-like being twisted by single or multiple conducting wires, outside conductor thread core
Extruded insulation, entire outside are surrounded by the coating (i.e. protective coverings of cable) of height barrier propterty.With the continuous hair of China's economy
Exhibition, the important job facilities such as subway, tunnel and skyscraper, the densely populated places occasion such as large supermarket, public arena, power load
Very big, cable laying is very intensive, and there are fire hazard, common cable can not ensure reliable under Fire Conditions without fire resistance
It is powered.
Utility model content
The purpose of this utility model is to provide a kind of extruded insulation fireproof power cables, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions：
A kind of extruded insulation fireproof power cable, including conductor thread core, copper strip shielding layer, the first inhibiting tape wrapping layer and outer
Sheath；The conductor thread core is made of more wire bodies and is provided with three groups, wraps up outside three groups of conductor thread cores after copper strip shielding layer
Side is provided with the first inhibiting tape wrapping layer, and the first inhibiting tape wrapping layer is provided with alkali-free glass at the position alternate with copper strip shielding layer
Glass silk filled layer is provided with separation sleeve on the outside of the first inhibiting tape wrapping layer, fire resisting separation layer is enclosed on the outside of separation sleeve,
The fire resisting separation layer is extruded by ceramic low-smoke halogen-free polyolefin refractory matter, is wound on the outside of the fire resisting separation layer
Second inhibiting tape wrapping layer.
As further program of the utility model：Between conductor thread core and copper strip shielding layer described in every group from inside to outside according to
It is secondary to be provided with conductor shield, insulating layer and insulation screen.
As the utility model further scheme：It is provided with armor, armour on the outside of the second inhibiting tape wrapping layer
It fills layer outer sheath and is equipped with oversheath.
As the utility model further scheme：The oversheath is made of LSOH anti-flaming polythene material.
Compared with prior art, the utility model has the beneficial effects that：The utility model is novel in design, the resistance to fire screen of setting
Absciss layer is extruded by ceramic low-smoke halogen-free polyolefin refractory matter, and hard pottery is produced under flame calcination or hot conditions
Porcelain hard shell, hard shell not melting are not dripped, and there is good heat-insulated fire insulation effect, the utility model to be set using proprietary structure
Meter, it is ensured that external heat will not be passed to inside cable core cable in the event of an accident, even if fire occurs it is also ensured that absolutely
The insulation effect of edge layer, it is ensured that the operation that cable can be safe and reliable within the regular hour wins preciousness for fire-fighting and rescue

The rated voltage of fire insulation effect, the cable is 6kV to 35kv.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.In addition, it should be understood that although this specification is described in terms of embodiments, but it is not each real
It applies mode only to contain an independent technical solution, this description of the specification is merely for the sake of clarity, this field skill
Art personnel should consider the specification as a whole, and the technical solutions in the various embodiments may also be suitably combined, form ability
The other embodiment that field technique personnel are appreciated that.
