Description
Technical field
The present invention relates to field of cables, is specifically a kind of cross-linked polyethylene insulation flame-retardant power cable.
Background technology
It is fire-retardant that traditional cable uses a large amount of metals to be used for, but metallic element can excessively cause the curvature of cable poor, holds
Easily there is appearance and flame retarding efficiency that folding line influences cable；Later stage improvement uses PVC, and PVC's is cheap, and fire resistance is good,
But PVC can release a large amount of toxic gases when burning, and now be prohibited from using, therefore solution pair should be continually looked on cable-flame retardant
Plan.
The content of the invention
To solve the above-mentioned problems, the present invention proposes a kind of cross-linked polyethylene insulation flame-retardant power cable.
A kind of cross-linked polyethylene insulation flame-retardant power cable, including cable core, the cable core are led for more annealed coppers
Body forms, and aluminium-plastic tape insulating layer is extruded with outside the copper conductor at the middle part, the aluminium-plastic tape insulating layer
Outside is extruded with metal armouring flame-retardant layer, outside the metal armouring flame-retardant layer it is twisted have it is several by aluminium-plastic tape insulating layer
The copper conductor of parcel, the outside of the aluminium-plastic tape insulating layer of the outside are surrounded with the nonwoven layer for providing buffering,
Fire-retardant butyronitrile layer is extruded with outside the nonwoven layer, the outside of the fire-retardant butyronitrile layer is extruded with the crosslinking for waterproof
Polyethylene layer, the edge of the metal armouring flame-retardant layer are concavo-convex for ease of what is be twisted.
Between the copper conductor and aluminium-plastic tape insulating layer, aluminium-plastic tape insulating layer and metal armouring flame-retardant layer it
Between, be both provided between metal armouring flame-retardant layer and nonwoven layer for filling and fire-retardant separation layer, the separation layer are
The compounding substances of glass fibre and gasket for packing.
The beneficial effects of the invention are as follows：For the present invention using crosslinked polyethylene as insulating sheath, crosslinked polyethylene is Halogen
Fire proofing, good mechanical property；Using metal armouring flame-retardant layer, three flame-retardant layers of fire-retardant butyronitrile layer and separation layer as protection,
The possibility of cable fire is substantially reduced, adds the service life of cable；The edge of the metal armouring flame-retardant layer is set
It is calculated as, easy to twisted concavo-convex, reduction slide displacement, internal support being provided for resistance external mechanical power.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the main structure diagram of the present invention.
Embodiment
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention easy to understand, below it is right
The present invention is expanded on further.
As shown in Figure 1, a kind of cross-linked polyethylene insulation flame-retardant power cable, including cable core, the cable core are more
Root annealing copper conductor 3 forms, and aluminium-plastic tape insulating layer 5 is extruded with outside the copper conductor 3 at the middle part, the plastic-aluminum is answered
The outside of crossed belt insulating layer 5 is extruded with metal armouring flame-retardant layer 4, and the outside of metal armouring flame-retardant layer 4 is twisted several quilts
The copper conductor 3 that aluminium-plastic tape insulating layer 5 wraps up, the outside of the aluminium-plastic tape insulating layer 5 of the outside, which is surrounded with, to be used for
The nonwoven layer 2 of buffering is provided, fire-retardant butyronitrile layer 1 is extruded with outside the nonwoven layer 2, the fire-retardant butyronitrile layer 1
Outside is extruded with the crosslinked polyetylene insulated layer 7 for waterproof, and the edge of the metal armouring flame-retardant layer 4 is for ease of twisted
It is concavo-convex.
Between the copper conductor 3 and aluminium-plastic tape insulating layer 5, aluminium-plastic tape insulating layer 5 and metal armouring it is fire-retardant
It is both provided between layer 4, between metal armouring flame-retardant layer 4 and nonwoven layer 2 for filling and fire-retardant separation layer 6, it is described
Separation layer 6 is glass fibre and the compounding substances of gasket for packing.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
