Abstract
The utility model provides a power transmission cable which adopts insulation of inorganic materials, and protection sleeve of metal materials, the utility model has the advantages of high-temperature resistant, fireproof, explosion protective, corrosion resistant, which is characterized in that: the cable core is made of copper, or copper alloys, belts made of inorganic materials is wrapped in laps or in longitude as a insulating layer, metal protection sleeve is wrapped outside the insulating layer, the protection sleeve is formed by covering and welding metal belts, the metal protection sleeve can be smooth or be rolled with veins.
Description
Technical field: the utility model belongs to field of cables, a kind of more precisely electric power cable.
Background technology: the power cable that uses adopts organic material such as rubber, plastics etc. to insulate usually at present, after power cable line catches fire, insulating material just can be totally burned, and can send smog and harmful substance, some organic material insulation after improving, although smog can obviously reduce when fire burns, the release of harmful substance also improves, but after fire burns, this electric wire circuit just can't work on.With the mineral insulated cable of metal oxides such as magnesia powder as insulation, improved above-mentioned shortcoming, but because on making, it is subjected to the metal tube length restriction as sheath, any length when cable can't need be accomplished; The core of cable, every phase all can only adopt a wires to make, and make cable very hard, are difficult to lay; Metal oxides such as magnesia powder are the moisture absorption very easily again, because of the moisture absorption reduces insulation resistance, handles so mineral insulated cable must carry out lengthy and tedious and strict termination again during use, could use safely.
Summary of the invention: the utility model is that a kind of electric power cable with good resistance to elevated temperatures will be provided, and it can make random length on demand, and comparatively soft, is convenient to lay; During use, though material on every side all fire burns, it still can not catch fire, and can not burn, a kind of never safe environment protection type cable of burning that can not produce smog and harmful substance.
The utility model is to finish by following mode: by the core that insulating tape wrapped up that inorganic material is made, many cores evenly distribute, and are vertically wrapped up by metal tape, and the place of cracking is welded into smooth tubular sheath, forms cable.
The mixed type inorganic material insulating tape of making by glass fibre, mica tape, asbestos yarn, metal oxide.Adopt wrapped or vertical wrapping on the core made.Many cores are 1～42.Core is to form by the multiply metal wire is stranded.Core is by copper, copper alloy, or other electric conducting material is formed.The multiply metal wire is 1～54 strand, and smooth tubular sheath can roll " line " thereon, forms the sheath of band " line ".Metal tape is a copper, copper alloy or stainless steel.
Implement the utility model, can make the cable of random length, it has high temperature resistant, fire prevention, advantage such as explosion-proof, corrosion-resistant.When transmission of electricity, can carry bigger current capacity, as fire any smog can not take place, do not produce any pernicious gas and toxin, can remain the electric power normal transmission, be a kind of never cable of burning.It can be used in skyscraper, permanent construction, it both can be used in the high temperature occasion, also can be used in the place that need take strict precautions against fire especially such as oil plant, steel mill, oil tanker, also be applicable to the place that needs special sanitation and hygiene such as hospital, food factory, meat-packing plant etc.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment: core, by the different requirements of specification of cable, adopt single core or multicore structure, each core can be that one or more metal wire is made, many metal wire strand system forms, and can use pressure-type structure in case of necessity; Each core is respectively with inorganic insulating material the band 2 wrapped or vertical insulation heart yearns 1 that are bundled into; For the cable that needs multicore structure, after making the insulation heart yearn, stranded again stranding.Coat the cable core that core is made by the inorganic insulating material band, adopt metal tape 3 vertical bag welding, postwelding is drawn into smooth metallic sheath pipe through online, just make the metal sheath inorganic insulated cable, if when requiring cable that better bending property is arranged, can roll smooth metallic sheath pipe and " line " that cable axis is perpendicular.
