Abstract
The utility model discloses a low-smoke halogen-free insulation and flame-retardation power cable for use in mines. The power cable comprises power insulating wire cores, an insulating layer, a mica tape fire retarding layer and a polyethylene sheath layer. The power insulating wire cores are successively wrapped, from outside to inside, by the mica tape fire retarding layer, an aluminum tape shielding layer and a silicone rubber insulating layer. Four power insulating wire cores form a cable core. The gap between the power insulating wire cores and the silicone rubber insulating layer is provided with a flame retardant and fire-resisting filling layer. The outer part of the mica tape fire retarding layer is formed in a manner that a low-smoke halogen-free polyethylene sheath layer and a glass fiber wrapping bag layer are closely wrapped. The aluminum belt shielding layer is provided with four monitoring wire cores. The power cable provided by the utility model finds applications in mines to resist high temperature and to resist twist; the power cable is also environmentally friendly and does not cause pollutions to an environment.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of low smoke and zero halogen insulation mining flame-retardant power cable.
Background technology
Current normally used cable, have can not high-low temperature resistant fire prevention etc. shortcoming, cable in colliery, its environment is often more severe, because cable needs to use out of doors for a long time, so just require cable to there is certain twisting resistance, resistance to bending and fire-resistant, even more important a bit, in the time of breaking out of fire, it can not discharge pernicious gas in the process of burning, otherwise can bring life threaten, and the function that these cables have on the market many cables do not reach.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide a kind of low smoke and zero halogen insulation mining flame-retardant power cable.
Scheme of the present utility model is as follows: a kind of low smoke and zero halogen insulation mining flame-retardant power cable, it is by insulated power core, insulating barrier, mica tape flame retardant coating and pe sheath layer, and described insulated power core ecto-entad is that mica tape flame retardant coating, aluminium strip screen and silicone rubber insulation layer extrude and form successively; Described four thoroughly do away with edge power core forms cable core; The gap portion of described insulated power cable core and silicone rubber insulation layer is provided with flame-retardant packed layer; Described mica tape flame retardant coating is outward closely to be extruded and form by low smoke and zero halogen pe sheath layer and glass fibre lapping layer; In described aluminium strip screen, be provided with four monitoring cores, described insulated power core is tinned copper wire stranded conductor.
The utlity model has in sum following beneficial effect: the utility model be applicable to field, colliery with high temperature resistant, twisting resistance is strong and the advantage such as environment friendly and pollution-free.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model:
Wherein: 1, insulated power core; 2, silicone rubber insulation layer; 3, aluminium strip screen; 4, monitoring core; 5 mica tape flame retardant coatings; 6, glass fibre lapping layer; 7, low smoke and zero halogen pe sheath layer; 8, fire-retardant gasket for packing.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: a kind of low smoke and zero halogen insulation mining flame-retardant power cable, it is by insulated power core 1, silicone rubber insulation layer 2, mica tape flame retardant coating 5 and pe sheath layer 7, and described insulated power core 1 ecto-entad is that mica tape flame retardant coating 5, aluminium strip screen 3 and silicone rubber insulation layer 2 extrude and form successively; Described four thoroughly do away with edge power core 1 forms cable core; The gap portion of described cable core and silicone rubber insulation layer 2 is provided with fire-retardant gasket for packing 8; Described mica tape flame retardant coating 5 is outer is closely to be extruded and form by 7 layers of low smoke and zero halogen pe sheaths and glass fibre lapping layer 6; In described aluminium strip screen 3, be provided with four monitoring cores 4, described insulated power core 1 is tinned copper wire stranded conductor.
Although above concrete mode of the present utility model has been given to describe in detail and explanation; but what should indicate is that we can change and amendment according to conception of the present utility model is carried out to various equivalences to above-mentioned various execution modes; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
