Abstract
The utility model discloses a high-temperature resistant and fire-proof power cable comprising a plurality of cores, each core comprises a conductor, a mica tape layer is wrapped outside each conductor, an insulation layer is wrapped outside each mica tape layer, a wrapping layer is arranged outside the cores, filler yarns are arranged in the gaps among the cores inside the wrapping layer, and a sheath is wrapped outside the wrapping layer. By adopting the structure, the utility model has the advantages that firstly, the power cable can run stably in a long term under high-temperature environment and can slow down the spread of fire; and secondly, the structure is simple and the effect is sound.
Description
Technical field
The utility model relates to the power cable technical field, particularly a kind of high temperature resistant, fireproof power cable.
Background technology
High speed development along with industries such as iron and steel, oil, space flight, chemical industry, metallurgy, traditional cable such as polyethylene/polyvinyl chloride insulated power cable cable can not adapt in the high temperature environment such as iron and steel, metallurgy, space flight, in the influence that adds oxidation and oxide etch, air-flow, granule impact etc., the drawback of traditional cable displays gradually, lower as long-term serviceability temperature, can not be used for the high temperature occasion, not have fire resistance etc.
The utility model content
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, provide a kind of can operation steady in a long-term under hot environment, can delay a kind of high temperature resistant, the fireproof power cable that spreads of the intensity of a fire.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of high temperature resistant, fireproof power cable, comprise many cores, described core comprises conductor, and the outer surface of described conductor is enclosed with the mica belt, the outer surface of described mica belt is provided with insulating barrier, in the periphery of all cores, establish one deck lapping layer, in the inside of described lapping layer, the gap that forms by described many cores, be provided with gasket for packing, described lapping layer outer surface is enclosed with sheath.
Described lapping layer is the glass fibre lapping layer.
Described insulating barrier is that glass fiber yarn braiding insulation dip-coating ptfe emulsion and sintering form.
Described sheath is that glass fiber yarn braiding insulation dip-coating ptfe emulsion and sintering form.
Described gasket for packing is the glass fibre gasket for packing.
The utility model adopts said structure, has the following advantages: 1, can steady in a long-termly under hot environment move, can delay spreading of the intensity of a fire; 2, simple in structure, respond well.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is a cross section structure schematic diagram of the present utility model;
In Fig. 1,1, conductor; 2, mica belt; 3, insulating barrier; 4, lapping layer; 5, gasket for packing; 6, sheath.
Embodiment
A kind of as shown in Figure 1 high temperature resistant, fireproof power cable, comprise many cores, described core comprises conductor 1, the outer surface of described conductor 1 is enclosed with mica belt 2, and the outer surface of described mica belt 2 is provided with insulating barrier 3, in the periphery of all cores, if one deck lapping layer 4, in the inside of described lapping layer 4, the gap that forms by described many cores, be provided with gasket for packing 5, lapping layer 4 outer surfaces are enclosed with sheath 6.Lapping layer 4 is the glass fibre lapping layer.Insulating barrier 3 weaves insulation dip-coating ptfe emulsion for glass fiber yarn and sintering forms.Sheath 6 weaves insulation dip-coating ptfe emulsion for glass fiber yarn and sintering forms.Gasket for packing 5 is the glass fibre gasket for packing.Closely connect between each member, constitute one.Glass fibre makes this cable can steady in a long-termly under hot environment move, can delay spreading of the intensity of a fire.Cable adopts the 1st or 2 class twisted copper conductors, selects the conductor of certain specification and the radical of definite single line for use according to GB/T3956.Will be drawn into required specification to copper cash according to above-mentioned, wire drawing is carried out on wire drawing machine and conductor is annealed, and annealing back resistance should reach standard, and the single line surface should smooth, no greasy dirt, cut etc.Select suitable thread reaming machine according to the concrete condition of conductor, the speed of twisted wire, the rotating speed of traction, will meet process stipulation.Mica tape adopts the wrapped form of putting up, and big probability is controlled at more than 25%, require wrapped smooth, corrugationless, no bottom pour ladle.Determine the thickness of glassfiber insulation so that select suitable glass fiber yarn according to technology, the form of glass fiber yarn braiding dip-coating ptfe emulsion and sintering is adopted in insulation, increases its resistance to elevated temperatures.Insulated wire cores is carried out stranding then, and the direction of stranding is generally dextrad.The stranding lay ratio will comply with relevant regulations, and the speed of each parts also will be followed the pertinent regulations of operation card.Fill and promptly the space of stranding is filled up, keep the rounding property of cable with glass fibre.The direction of glass fiber tape is a left-hand, and employing is put up wrapped, puts up size and is that the 10%-15% of twining package tape width, wrapping angle are 25 °-40 °.Protective cover material adopts glass fiber yarn braiding dip-coating ptfe emulsion and sintering.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection range of the present utility model.
