Description
Technical field
Field of cable technology is the utility model is related to, particularly relates to a kind of flexible mineral insulation fireproof cable knot
Structure.
Background technology
Electric wire refers to the wire rod for electric power, communication and associated transport purposes, is to convey electric energy, transmission information and enter
Row electromagnetic conversion and the various motors of manufacture, electrical equipment, the indispensable basic equipment of instrument institute.Our times resource is increasingly tight
, it is also extremely strict to material used in electric wire, for the electronic material for lead frame, terminal, connector etc.,
Fundamental characteristics as product, it is desirable to which high intensity and high electric conductivity or thermal conductivity have both.
The growth of China's economic continuously and healthily, provides the huge market space for cable products, and Chinese market is strong
Temptation so that sight is all focused on Chinese market by the world, in short decades of reforming and opening up to the outside world, Chinese cable manufacturing industry institute
The huge production capacity formed allows the world to regard with special esteem.With China electric power industry, data communication industry, urban track traffic industry,
The continuous expansion of the industry size such as car industry and shipbuilding, the demand of electric wire will also be increased rapidly, following electric wire
Industry also has huge development potentiality.
With the popularization of power cable, cable fault rate also increases therewith.Cable often leads to electrical fire, surrounding
Adjacent cable is also destroyed, and irremediable loss is caused to whole power system.
Utility model content
For deficiency of the prior art, the technical problems to be solved in the utility model is the provision of a kind of flexible mineral
Insulated cable structure.
In order to solve the above technical problems, the utility model is realized by following scheme：A kind of flexible mineral insulation fire prevention
The construction of cable, the construction of cable include：
Sheath, the sheath are placed in outermost layer, and the sheath is halogen-free and low-smoke flame-retardant polyolefin sheathed；
Separation layer, described to isolate the internal layer for being placed on sheath, the separation layer is ceramic polyolefin separators；
At least one cable core, the outer layer of the cable core and intermediate layer be respectively ceramic polyolefin insulation layer,
The wrapped flame retardant coating of synthetic mica, innermost layer are copper conductor；
The cable core is placed in separation layer, and the gap location between the cable core and the separation layer is filled with
Glass cord；
The glass cord outer layer is wound with least one layer of glass fiber tape.
Further, the copper conductor includes folded tight more copper wires together.
Further, the cable core is provided with five, and its circular array is placed in separation layer.
Further, the glass fiber tape is provided with two layers, and layer glass fiber band tightens glass cord in netted.
Relative to prior art, the beneficial effects of the utility model are：The utility model construction of cable can prevent fires, outermost
Layer use is halogen-free and low-smoke flame-retardant polyolefin sheathed, and the sheath has fire resistance property；It is halogen-free and low-smoke flame-retardant polyolefin sheathed to be not easy
Burning, even if it produces few smog after burning, fire proofing can prevent the condition of a fire from expanding.
Separation layer is ceramic polyolefin separators, therefore, can be with absorbing cable because ceramics have the cold fast function of effect
The heat in portion also has heat sinking function to outside, while for isolating；
Ceramic polyolefin insulation layer is used to insulate, and avoids short circuit, and the wrapped flame retardant coating of synthetic mica is used to prevent fires.
The utility model construction of cable uses multiple fireprotection layers, construction of cable fire resistance property is greatly strengthened, can make
Obtain power system stability.
Brief description of the drawings
Fig. 1 is the utility model flexible mineral insulation fireproof cable section of structure；
Fig. 2 is the utility model cable core structural representation.
Marked in accompanying drawing：The wrapped flame retardant coating 2 of copper conductor 1, synthetic mica, ceramic polyolefin insulation layer 3, glass cord
4th, glass fiber tape 5, separation layer 6, sheath 7.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
It refer to accompanying drawing 1-2, a kind of flexible mineral insulation fireproof cable structure of the present utility model, the construction of cable bag
Include：
Sheath 7, the sheath 7 are placed in outermost layer, and the sheath 7 is halogen-free and low-smoke flame-retardant polyolefin sheathed, and the sheath 7 is prevented fires
Ability is strong；It is halogen-free and low-smoke flame-retardant polyolefin sheathed not allow easy firing, even if it produces few smog, fire proofing energy after burning
Enough prevent the condition of a fire from expanding；
Separation layer 6, the separation layer 6 are placed in the internal layer of sheath 7, and the separation layer 6 is ceramic polyolefin separators, due to
Ceramics have the fast function of cold effect, therefore, can also have radiating with the heat inside absorbing cable to outside, while for isolating
Function；
At least one cable core, the outer layer of the cable core and intermediate layer be respectively ceramic polyolefin insulation layer 3,
The wrapped flame retardant coating 2 of synthetic mica, innermost layer are copper conductor 1；Preferred scheme is that cable core is provided with five, and its circular array is put
In in separation layer 6.The copper conductor 1 includes folded tight more copper wires together.
The cable core is placed in separation layer 6, the gap location filling between the cable core and the separation layer 6
