Abstract
The utility model relates to a silicone rubber cable for a high speed locomotive with excellent performances of flame retardation, wear resistance and grease resistance. The silicone rubber cable comprises an inner core conductor twisted by a plurality of tined soft copper wires. The inner core conductor is extruded with a separating layer 1, an insulating layer, a separating layer 2 and a protective layer from inside to outside. The separating layer 1 is a non-hygroscopic isolation strip made of polyolefin or a conductor screen. The separating layer 2 is a non-hygroscopic isolation strip made of polyolefin. The protective layer is a sheath made of cross-linked silicone rubber or cross-linked ethylene copolymer or a braided fabric made of glass fiber. The silicone rubber cable has the following advantages that, the cable is peripherally provided with the protective layer, the cable is ensured to work under the condition of high temperature, and the cable is more wear-resistant; the protective layer and the separating layer of the cable are made of grease resistant materials, so that the cable has the performance of grease resistance; and a defrosting agent added in the material of the insulating layer makes the surface of the insulating layer free of frost, tightness between the layers of the cable is ensured and the added fire retardant enables the fire retardant function of the insulating layer to be stronger.
Description
Technical field
The utility model relates to one, and not only fire resistance is good, and express locomotive silicone rubber for cable more wear-resisting, oil resistant, belongs to handling cable technical field.
Background technology
CN 201134286 Y, title " a kind of fire retardant high temperature electric cable for rolling stock of railway ", there is insulating barrier in online core conductor outside, and core conductor is equipped with separator, and silicone rubber insulation layer has been extruded in separator outside.Separator is made up of colour or the coiling of black polyester film.Core conductor is strands flexible conductor, filament diameter 0.2-0.5mm.Core conductor is stranded soft tinned conductor.Shortcoming: this kind of fire retardant high temperature electric cable for rolling stock of railway do not have protective layer resistance to wear poor, and silicone rubber insulation layer surface there will be easy generation between bloom phenomenon and separator local the disengaging, to affect use.
Utility model content
Purpose of design: for avoiding the deficiency in background technology, not only fire resistance is good for design one, and express locomotive silicone rubber for cable more wear-resisting, oil resistant.
Design: for realizing above-mentioned purpose of design.1, interior core conductor outside, by the interior design that is extruded with successively outward separator, insulating barrier, separator, protective layer, is one of technical characterictic of the present utility model.The object of design is like this: interior core conductor outside is by the interior separator one that is extruded with successively outward, insulating barrier, separator two, protective layer, interior core conductor is stranded by the zinc-plated soft copper of multiply, the Cable Bending Radius of making is like this little, be convenient to connect up in compartment, protective layer can guarantee that cable normally uses and has certain electrical breakdown effect under the working temperature of 120 ℃, protective layer is wear-resisting simultaneously, oil resistant adequately protects for interior core conductor provides, insulating barrier has good in electro ultrafiltration, in the time of breaking out of fire, insulating layer material has fire-retardant simultaneously, the functions such as low burning smoke, separator one between separator and protective layer and insulating barrier between insulating barrier and interior core conductor, separator two makes interior core conductor, insulating barrier and protective layer are close to mutually, guaranteed that layer and interlayer can not bond mutually simultaneously, conveniently peel off use, make separator, insulating barrier, in the compound-material of separator and protective layer, all do not contain halogen, like this in the time of breaking out of fire, the separator one of cable outer surface, insulating barrier, when separator two and protective layer can be heated volatilization, can not produce poisonous halide gas, guarantee passenger's life security.2, separator one and separator two are the non-hygroscopic isolation strip of being made up of polyolefin or are the design of conductor screen, are two of technical characterictics of the present utility model.The object of design is like this: the separator between insulating barrier and interior core conductor can be the non-hygroscopic isolation strip of being made up of polyolefin, also can be conductor screen, for the anti-interference cable that requires low wiring occasion to use, separator one in cable between insulating barrier and interior core conductor, separator two can be selected the non-hygroscopic isolation strip of being made up of polyolefin, this cable production cost is low, for the anti-interference cable that requires high wiring occasion to use, separator one in cable between insulating barrier and interior core conductor is conductor screen, make cable there is good function of shielding.3, insulating barrier is made up of silicon rubber, in this silicon rubber, be added with defrosting compound for eliminating silicone rubber for cable insulating surface bloom phenomenon and for improving the design of triazines fire retardant, zinc oxide and Firebrake ZB of the smokeless fire resistance of silicon rubber, be three of technical characterictic of the present utility model.The object of design is like this: insulating barrier is made up of silicon rubber; silicon rubber has good in electro ultrafiltration; simultaneously oil resistant, lower temperature resistance are strong; but other characteristics are general; in silicon rubber, add triazines fire retardant and zinc oxide and Firebrake ZB auxiliary flame retardant; strengthen the smokeless fire-retardant performance of silicon rubber, in silicon rubber, added defrosting compound to make the insulating barrier of making in use there will not be surperficial bloom phenomenon, thereby avoided insulating barrier and protective layer etc. to occur empty rising.4, protective layer is the sheath be made up of cross-linked silicone rubber or cross-linked ethylene copolymer or the design for the braid be made up of glass fibre, is four of technical characterictic of the present utility model.The object of design is like this: protective layer is the sheath be made up of cross-linked silicone rubber or cross-linked ethylene copolymer or the braid for being made up of glass fibre, and protective layer meets the demand of various wirings occasion in the situation that of assurance self function like this.
Technical scheme: a kind of express locomotive silicone rubber for cable, comprise the interior core conductor stranded by the zinc-plated soft copper of multiply, described interior core conductor outside is by interior separator one, insulating barrier, separator one, the protective layer of being extruded with successively outward; Described separator one is the non-hygroscopic isolation strip of being made up of polyolefin or is conductor screen; The non-hygroscopic isolation strip of described separator two for being made by polyolefin; Described protective layer is the sheath of being made up of cross-linked silicone rubber or cross-linked ethylene copolymer or is the braid of being made up of glass fibre.
The utility model compared with background technology, the one, silicone rubber for cable peripheral hardware protective layer for express locomotive, can not only guarantee that cable at high temperature works, and make cable more wear-resisting; The 2nd, express locomotive is oil resisting material with silicone rubber for cable protective layer and insulating barrier and makes, and makes cable have more oil resistance; The 3rd, the defrosting compound adding in insulating layer material makes surface of insulating layer can not go out frost, has guaranteed the compactness of the each interlayer of cable, and the fire retardant of interpolation makes insulating barrier anti-flaming function stronger.
