Abstract
The utility model discloses a heat resistant aluminium alloy cable. The heat resistant aluminium alloy cable comprises insulation power wire cores, inorganic flame-retardant fiber ropes, a glass fiber belt belting layer, and a flame-retardant silicon rubber external sheath layer, wherein the insulation power wire cores are formed by squeezing flame-retardant silicon rubber insulation layers on aluminium alloy conductors; the three power wire cores are stranded at intervals to form a cable core; a ceramic flame-retardant filling layer is squeezed at the central part of the three power wire cores; a monitoring wire core is disposed in the ceramic flame-retardant filling layer; the intervals of the cable core are filled with inorganic flame-retardant fiber ropes, and the glass fiber belt belting layer is disposed outside the cable core; and the glass fiber belt belting layer is covered by the flame-retardant silicon rubber external sheath layer. The heat resistant aluminium alloy cable has advantages of being simple in structure design, being stable in performance, being capable of fulfilling performance requirements of high-temperature-resistant and flame-retardant cables, being easy to lay due to the flexibility of the cable, being capable of preventing the monitoring wire core from the influence of high temperature by employing the ceramic flame-retardant filling layer, and being capable of guaranteeing electrical performances and monitoring effects.
Description
Technical field
The utility model relates to cable, relates in particular to heat resistant type aluminium alloy cable.
Background technology
Current normally used aluminum alloy cable conductor adopts aluminium alloy, insulation adopts crosslinked polyethylene or polyvinyl chloride, its thermal endurance class is poor and pliability is inadequate, Cable Bending Radius is large, the utility model is by the material of change structure and conductor, insulation and sheath, the pliability that improves thermal endurance class and cable, makes Cable Bending Radius little, has feature fire-retardant, heat-resisting, excellent electrical properties.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide heat resistant type aluminium alloy cable.
Scheme of the present utility model is as follows: heat resistant type aluminium alloy cable, it is made up of insulated power core, inorganic fire-retarded cordage, glass fibre belt lapping layer and flame-proof silicon rubber external sheath layer, and described insulated power core is to be extruded on aluminium alloy stranded conductor and to be formed by flame-proof silicon rubber insulating barrier; Described three thoroughly do away with edge power core interval is twisted into cable core; Described three thoroughly do away with the middle ceramic flame-proof packed layer that is extruded with of edge power core; In described ceramic flame-proof packed layer, be provided with monitoring core; Described cable core gap-fill has inorganic fire resistance fibre rope, and cable core is provided with glass fibre belt lapping layer outward; Described flame-proof silicon rubber external sheath layer covers on glass fibre belt lapping layer.
The beneficial effects of the utility model: the utility model structural design is simple; stable performance, can meet high temperature resistant and performance requirement flame retardant cable, and cable softness is easy to lay; ceramic flame-proof packed layer can protect monitoring core not to be subject to temperatures involved, ensures electric property and monitoring effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Wherein: 1, insulated power core; 2, aluminium alloy stranded conductor; 3, flame-proof silicon rubber insulating barrier; 4, inorganic fire-retarded cordage; 5, glass fibre belt lapping layer; 6, flame-proof silicon rubber external sheath layer; 7, monitoring core; 8, ceramic flame-proof packed layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, heat resistant type aluminium alloy cable, it is made up of insulated power core 1, inorganic fire-retarded cordage 4, glass fibre belt lapping layer 5 and flame-proof silicon rubber external sheath layer 6, and described insulated power core 1 is to be extruded on aluminium alloy stranded conductor 2 and to be formed by flame-proof silicon rubber insulating barrier 3; Described three thoroughly do away with edge power core 1 interval is twisted into cable core; Described three thoroughly do away with the middle ceramic flame-proof packed layer 8 that is extruded with of edge power core 1; In described ceramic flame-proof packed layer 8, be provided with monitoring core 7; Described cable core gap-fill has inorganic fire resistance fibre rope 4, and cable core is provided with glass fibre belt lapping layer 5 outward; Described flame-proof silicon rubber external sheath layer 6 covers on glass fibre belt lapping layer 5.
The conductor of insulated power core 1 forms by aluminium alloy conductor is stranded; make the bending radius of cable more much smaller than copper core cable; more easily lay; insulated power core 1 insulating barrier adopts flame-proof silicon rubber insulation; silastic material has heat resisting temperature height and good electric property; be conducive to the operation of cable under hot conditions; and the silicon dioxide of producing afterwards in burning is insulator; this is very favourable concerning flame retardant cable; ceramic flame-proof packed layer 8 can protect monitoring core 7 not to be subject to temperatures involved, ensures electric property and monitoring effect.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
