Description
[technical field]
The utility model relates to power cable technical field, specifically a kind of high temperature-resistant cable for body of wall through-Penetration portion.
[background technology]
Cable is part important in electric power transport, but at some Code in Hazardous Special Locations, due to the temperature drift of operational environment, the easy temperature distortion of cable, causes potential safety hazard.Therefore, in some high temperature places, high temperature-resistant cable usually can be used to replace common cable, thus ensure the stable of electric power transport and fail safe.At present, the structure of high temperature-resistant cable comprises that conductor, extruded insulation layer, stranding are stranded, lapping layer, restrictive coating, insulating barrier requires to select different heat-resistant insulation materials to wrap up in the outside investing conductor according to temperature resistant grade, lapping layer is wrapped in into the outside of cable core, and restrictive coating wraps up in the outside investing lapping layer.Cable uses in high temperature environments, because heat-resistant insulation material is all thermoplastic, at high temperature easily temperature distortion, particularly cable local is by mechanical stress position, insulation is more easily out of shape, after distortion, insulation thickness is uneven, the resistance to electric field strength performance of insulating barrier reduces, directly may there is leaky in some, and along with the prolongation of service time, because insulation is all organic thermoplastic, plasticizing distortion can be there is in thermoplastic under uniform temperature condition, when temperature is higher, meeting cracking is aging, finally lose electrical insulation capability, produce Electrical Safety accident, the very large hidden danger to Electrical Safety band.
[utility model content]
The purpose of this utility model is exactly to solve cable of the prior art in hot environment and slowly produce aging by insulation distortion and insulation under mechanical stress effect, finally lose electrical insulation capability, produce the not enough and defects such as Electrical Safety accident, a kind of novel structure is provided, safe and reliable, can on the basis ensureing cable original function, improve the high temperature-resistant cable of cable heat-resisting ability and cable safety in utilization in high temperature environments, it comprises conductor, it is characterized in that the fixture comprising cable body He be located at body of wall through-Penetration portion, described fixture comprises insulator, conduit, conduit comprises some first segmentations and some second segmentations, the external diameter of the first segmentation is less than the external diameter of the second segmentation, fixture has flame retardant coating, and described insulator is located in conduit, and insulator has insulation crust, described insulation crust is made up of mineral fibres, cable body comprises conductor, described conductor outside surfaces is coated with and is soaked with poly-carbon siloxanes thus forms high temperature resistant inorganic insulating coating, described high temperature resistant inorganic insulating coating outer surface extruded insulation layer, form high-temperature insulation core thus, the many stranded formation cables of high-temperature insulation core, cable outer surface is provided with outer jacket.
Described conductor is copper.
Described insulating barrier is made up of organic insulating material.
Described organic insulator is natural resin or thermoplastic resin or thermosetting resin or epoxy resin.
Described outer jacket is made up of inorganic mineral material.
Described outer jacket is also provided with sheath outward.
Described sheath is fire-retardant fluoroplastics sheath.
Compared with the existing technology, its advantage is that the utility model passes through, at conductive surface dip-coating high-temperaure coating, to make cable have resistance to elevated temperatures to the utility model; The insulating barrier extruded is high-temperaure coating protective layer, and insulating material performance requirement is not high, and technique is relatively simple.Cable runs relatively stable, reliable in high temperature environments.The utility model improves the fail safe that cable runs under the high temperature conditions, and make the range of application of high temperature-resistant cable wider, adaptability is stronger.

As shown in the figure, in figure: 1. conductor 2. high temperature resistant inorganic insulating coating 3. insulating barrier 4. outer jacket.
Fig. 1 is specified to be Figure of abstract of the present utility model.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Corrosion proof cable of the present utility model mainly comprises cable body and is located at the fixture of body of wall through-Penetration portion, described fixture comprises insulator, conduit, conduit comprises some first segmentations and some second segmentations, and the external diameter of the first segmentation is less than the external diameter of the second segmentation; Fixture has flame retardant coating, and described insulator is located in conduit, and insulator has insulation crust; Described insulation crust is made up of mineral fibres; Cable body comprises conductor 1, high temperature resistant inorganic insulating coating 2, insulating barrier 3, outer jacket 4.High temperature resistant inorganic insulating coating 2 wraps up in the outside investing conductor 1, its specifically conductive surface repeatedly dip-coating gather carbon siloxanes, and cure process by nitrogen, form one deck densification, pliable and tough high temperature resistant inorganic insulating coating at conductive surface, there are higher heat resistance and insulation property.Insulating barrier 3 is wrapped in the outside of high temperature resistant inorganic insulating coating 2; form high-temperature insulation core thus; outer jacket 4 is wrapped in the outside by the stranded cabling structure of many high-temperature insulation cores; this insulating barrier and outer jacket protection high-temperaure coating are in follow-up cable processing or be not damaged in using; and make thus cable at high temperature continuous service time, ensure the integral insulation performance of cable.
