Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide the corrosion-resistant power cable of a kind of heat-insulating flame-retardant.
The present invention takes following technical scheme to realize: the corrosion-resistant power cable of a kind of heat-insulating flame-retardant, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with many conductors; Described conductor closely wraps up one deck ripple tube layer outward; Described ripple tube layer and conductor form cable core jointly; The gap portion of many described conductor is provided with a carbon fiber composite core rod; Described cable core closely extrudes a layer insulating outward; Gap portion between described cable core and insulating barrier is provided with packed layer; Described insulating barrier closely extrudes one deck screen outward; One deck fire-resistant isinglass belt is extruded outside described screen; Described fire-resistant isinglass belt outer surface extrudes one deck heat-insulating flame-retardant layer; Described heat-insulating flame-retardant layer extrudes inner sheath and oversheath from inside to outside successively.
The above-mentioned corrosion-resistant power cable of a kind of heat-insulating flame-retardant, described conductor is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire.
The above-mentioned corrosion-resistant power cable of a kind of heat-insulating flame-retardant, the heat-insulating flame-retardant layer that described cable body inside is arranged is made up of basalt fibre.
The above-mentioned corrosion-resistant power cable of a kind of heat-insulating flame-retardant, described insulating barrier, screen and fire-resistant isinglass belt are even to outdiffusion centered by the carbon fiber composite core rod of cable body inside setting.
The above-mentioned corrosion-resistant power cable of a kind of heat-insulating flame-retardant, described inner sheath and oversheath are made up of Ceramic silicon rubber.
The above-mentioned corrosion-resistant power cable of a kind of heat-insulating flame-retardant, described insulating barrier, screen, Thickness Ratio between fire-resistant isinglass belt and heat-insulating flame-retardant layer are 1:1:1:1.
The present invention has following beneficial effect in sum: this cable has good shielding properties, resist bending performance and the characteristic such as high temperature resistant, also there is high pressure resistant and diamagnetic jamming performance simultaneously, described inner sheath and oversheath adopt Ceramic silicon rubber to make, because Ceramic silicon rubber is a kind of novel polymer composite, when flame combustion, hard ceramic-like shell can be formed, and temperature is higher, housing is harder, can play the effect of well fire prevention and fire insulation.

Wherein: 1, cable body; 2, conductor; 3, ripple tube layer; 4, carbon fiber composite core rod; 5, packed layer; 6, insulating barrier; 7, screen; 8, fire-resistant isinglass belt; 9, heat-insulating flame-retardant layer; 10, inner sheath; 11, oversheath.
Embodiment
As shown in Figure 1, the corrosion-resistant power cable of a kind of heat-insulating flame-retardant, it comprises cable body 1, and described cable body 1 comprises conductor 2, insulating barrier 6, screen 7 and oversheath 11, and described cable body 1 cross section is circular configuration; Described cable body 1 inside is provided with many conductors 2; Described conductor 2 outer closely parcel one deck ripple tube layer 3; Described ripple tube layer 3 and conductor 2 form cable core jointly; The gap portion of many described conductor 2 inside is provided with a carbon fiber composite core rod 4; Described cable core closely extrudes a layer insulating 6 outward; Gap portion between described cable core and insulating barrier 6 is provided with packed layer 5; Described insulating barrier 6 is outer closely extrudes one deck screen 7; One deck fire-resistant isinglass belt 8 is extruded outside described screen 7; Described fire-resistant isinglass belt 8 outer surface extrudes one deck heat-insulating flame-retardant layer 9; Described heat-insulating flame-retardant layer 9 extrudes inner sheath 10 and oversheath 11 from inside to outside successively.
The conductor 2 that described cable body 1 inside is arranged is any one in single copper wire, stranded bare copper wire or stranded tinned copper wire, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor 2 structure is easy to processing, making length is unrestricted, there is during use certain flexibility and bendability, facilitate the laying of workpeople; The outer ripple tube layer 3 arranged of described conductor 2 can play the effect of protection conductor 2, prevents conductor 2 because being subject to the excessive fracture causing conductor 2 of external force; The carbon fiber composite core rod 4 that described conductor 2 inside is arranged has stronger tensile strength, and lightweight, and flexibility is good, can effectively prevent cable deadweight and ambient pressure to the destruction of cable; The packed layer 5 arranged between described conductor 2 and insulating barrier 6 makes the internal structure of cable body 1 compacter, there will not be the situation that conductor 2 offsets; Described insulating barrier 6 makes the stability of cable improve, and insulating barrier 6 skin-friction coefficient is large, and cable is when uninterrupted bending, and insulating barrier 6 also relative displacement can not occur, thus ensures the normal output of electric property; Described screen 7 can well avoid the electromagnetic interference that cable is mutual when outside usage data exchanges, eliminate external electromagnetic interference signal to the interference of cable, and screen 7 cost formed than the braiding of general used copper mesh is lower, size also can reduce to some extent, effectively can improve the quality of cable transmission signal; The outer fire-resistant isinglass belt 8 arranged of described screen 7 is excellent insulating material, can meet cable completely and keep good insulation property in flame calcination situation, ensures cable energy continuation electric energy transmitting; Described heat-insulating flame-retardant layer 9 adopts basalt fibre to form, thus makes cable have good resistance to elevated temperatures, and has good heat-proof quality, plays high temperature resistant and fire-retardant effect to cable; Described inner sheath 10 and oversheath 11 adopt Ceramic silicon rubber to make, because Ceramic silicon rubber is a kind of novel polymer composite, when flame combustion, hard ceramic-like shell can be formed, and temperature is higher, housing is harder, can play the effect of well fire prevention and fire insulation.
