Abstract
The utility model relates to a fire-resistant cable capable of being repeatedly used, which comprises at least two insulated wire cores, wherein each insulated wire core is covered with a belting layer; a filler is arranged between the insulated wire cores and the belting layers as well as between the insulated wire cores; each belting layer is covered with a sheath layer; and each insulated wire core comprises a conductor layer, a mica tape layer, a low smoke and zero halogen glass fiber tape layer and a glass fiber braiding layer. As all of the cable materials adopted by the fire-resistant cable are inorganic materials, the cable in a burning environment is prevented from spontaneous combustion, the requirements of high-temperature site and fire resistance can be met, and the cable can still be used without being replaced even after burned; and as the conductors in the cable structure are stranded conductors, and the insulated and sheath materials are all wrapped or woven, the cable provided by the utility model is more flexible, and can meet the requirement of use in a movable bending occasion.
Description
Technical field
The utility model relates to a kind of fire-resisting cable, relates in particular to a kind of reusable fire-resisting cable, belongs 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 a mineral insulated cable, and product structure is outside copper sheath pipe, and the center is a 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.
The utility model content
The utility model provides a kind of reusable fire-resisting cable at the fire-resisting cable above shortcomings of existing two kinds of structures, and 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 utility model 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 beneficial effects of the utility model are: the cable material that the utility model fire-resisting cable adopts all is an 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 the utility model cable is soft, can satisfy and move the needs that crooked occasion is used.
On the basis of technique scheme, the utility model can also be done 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 a 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 utility model.

Described conductor layer 1 is made of bundle strand copper wire, and described bundle strand copper wire is tinned copper wire or silver-gilt copper wire.Described filler 5 is a glass cord.Described restrictive coating 7 oppositely is made of with the ingot braiding tinned copper wire and glass cord, and count is 100%, can prevent to damage in the mobile use cable insulation core.Described fiberglass braided layer 4 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 2 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 3 adopts vertical bag.The count of described fiberglass braided layer 4 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 utility model, the stranding pitch diameter guarantees the whole flexibility of cable less than 16 times.
The above only is preferred embodiment of the present utility model, and is in order to restriction the utility model, not all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
