Abstract
The invention relates to a reusable fire-resistant cable. The fire-resistant cable comprises at least two mutually-twisted insulating cable cores, wherein a tape-wrapping layer is wrapped outside the insulating cable core; fillers are arranged between the insulating cable cores and the tape-wrapping layer, as well as between the insulating cable cores; a sheath layer is wrapped outside the tape-wrapping layer; and the insulating cable core comprises a conductor layer, a mica tape layer, a low-smoke halogen-free glass fibre tape layer and a glass fibre weaved layer. The cable material used by the fire-resistant cable disclosed by the invention is all inorganic material, the cable cannot be self-combusted in an ignition environment and can meet the needs of high-temperature occasions and fire resistance; the cable can continue to be used after being ignited, so that the cable does not need to be replaced; and because a conductor in the cable structure is a bunch-stranded conductor, and the insulating material and the sheath material are both in the form of lapping or weaving, the cable disclosed by the invention is flexible and capable of meeting the use needs of mobile bending occasions.
Description
Technical field
The present invention relates to a kind of fire-resisting cable, relate in particular to a kind of reusable fire-resisting cable, belong to the electric wire field.
Background technology
The structure of existing fire-resisting cable has two kinds, a kind of is to be made of conductor, mica tape, insulation and sheath, the fire-resisting cable of this structure can be made the soft junction structure, also can make fixedly laying structure, and this kind cable insulation generally adopts organic material, so the serviceability temperature of cable is not high, be subjected under the situation of fire because the existence of organic material in the construction of cable at cable in addition, after the fire, the construction of cable is damaged, the cable that must more renew causes the wasting of resources.Another is mineral insulated cable, and product structure is outside copper sheath pipe, and the center is copper conductor, and the middle magnesium oxide of filling is done insulating barrier, and this kind structural cable hardness is big, lays difficulty, and not soft, joint hidden danger is many, increases cost and engineering time.
Summary of the invention
The present invention is directed to the fire-resisting cable above shortcomings of existing two kinds of structures, a kind of reusable fire-resisting cable is provided, this fire-resisting cable is made easily, and delivery length is unrestricted, and the temperature resistant grade height is soft and reusable.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of fire-resisting cable comprises at least two mutual stranded insulated wire cores, described insulated wire cores is wrapped with belting layer, be provided with filler between described insulated wire cores and the belting layer and between the insulated wire cores, described belting layer is wrapped with restrictive coating, described insulated wire cores comprises conductor layer, the mica belt, low smoke and zero halogen glass fibre belt and fiberglass braided layer, described conductor layer is wrapped with the mica belt, described mica belt is wrapped with low smoke and zero halogen glass fibre belt, and described low smoke and zero halogen glass fibre belt is wrapped with fiberglass braided layer.
The invention has the beneficial effects as follows: the cable material that fire-resisting cable of the present invention adopts all is inorganic material, cable can self not burn in the environment that catches fire, at-60 ℃--800 ℃ medium-term and long-term use of environment, can satisfy high temperature occasion and fire-resistant needs, this cable can continue to use after catching fire, and do not need to change cable, because conductor is bundle strand conductor in the construction of cable, insulation and sheath material all are wrapped or type of weave, therefore cable of the present invention is soft, can satisfy the needs that mobile crooked occasion is used.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described conductor layer is made of bundle strand copper wire.
Further, described bundle strand copper wire is tinned copper wire or silver-gilt copper wire.
Further, described filler is glass cord.
Further, described restrictive coating is woven mutually by tinned copper wire and glass cord and forms.
Further, described fiberglass braided layer is formed by the glass cord braiding, and the diameter of described glass cord is greater than or equal to 0.4 millimeter.
Description of drawings
Fig. 1 is the structural representation of the reusable fire-resisting cable of the present invention.
Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used for explaining the present invention, is not for limiting scope of the present invention.
Fig. 1 is the structural representation of the reusable fire-resisting cable of the present invention.As shown in Figure 1, described fire-resisting cable comprises at least two mutual stranded insulated wire cores, described insulated wire cores is wrapped with belting layer, be provided with filler between described insulated wire cores and the belting layer and between the insulated wire cores, described belting layer is wrapped with restrictive coating, described insulated wire cores comprises conductor layer, the mica belt, low smoke and zero halogen glass fibre belt and fiberglass braided layer, described conductor layer is wrapped with the mica belt, described mica belt is wrapped with low smoke and zero halogen glass fibre belt, and described low smoke and zero halogen glass fibre belt is wrapped with fiberglass braided layer.
Described conductor layer is made of bundle strand copper wire, and described bundle strand copper wire is tinned copper wire or silver-gilt copper wire.Described filler is glass cord.Described restrictive coating oppositely is made of with the ingot braiding tinned copper wire and glass cord, and count is 100%, can prevent from damaging in the mobile use cable insulation core.Described fiberglass braided layer is formed by the glass cord braiding, and the diameter of described glass cord is greater than or equal to 0.4 millimeter.
Described mica belt adopts double-deck oppositely overlapping wrapped, and the rate of putting up is wrapped above 50%, the low smoke and zero halogen glass fibre belt of vertical bag one deck Duplication 20% outside the mica belt.Described low smoke and zero halogen glass fibre belt adopts vertical bag.The count of described fiberglass braided layer is 100%, and diameter is not less than 0.4mm, and angle of weave is adjusted to below 30 degree during braiding, and the low smoke and zero halogen glass fibre belt under the braid is played the effect of tightening.Glass cord diameter in the described fiberglass braided layer is regulated accordingly according to the size of cable area.
During insulated wire cores stranding of the present invention, the stranding pitch diameter guarantees the whole flexibility of cable less than 16 times.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
