Abstract
The utility model discloses a flexible fire resisting cable of high strength, which comprises a plurality of conductors, every conductor outward all in proper order the cladding have flame retardant coating and silicone rubber insulating layer to constitute insulation core, many insulation core annular intervals set up the constitution cable core, the cable core center is equipped with the steel wire and weaves a section of thick bamboo, cable core extrusion molding is in low smoke and zero halogen flame retardant polyolefin separates the oxygen layer, low smoke and zero halogen flame retardant polyolefin separates the oxygen layer and two -layerly comprises inside and outside, the inside and outside fibrage of the nai high temperature glass layer that is equipped with between two -layer, low smoke and zero halogen flame retardant polyolefin separates outside the oxygen layer in proper order, and the cladding has around the covering, the enhancement layer, the band layer, crowded package has low smoke and zero halogen flame retardant polyolefin oversheath layer outside the band layer. The utility model discloses structural design is novel, is applicable to the power supply and distribution system of high fire -retardant requirements such as cable pit, cable shaft, tunnel, and places such as specially adapted school, market, government organs have good low cigarette, have steamed, flame retardant efficiency, high temperature resistance can, mechanical properties is remarkable.
Description
technical field:
The utility model relates to cable, particularly relates to a kind of high-strength flexible fire-resisting cable.
background technology:
Current domestic common fire-resisting cable is by copper conductor, mineral insulation and and the rigidity fire-resisting cable that forms of copper sheath.Rigidity fire-resisting cable has very high fire resistance, but because adopt copper sheath, production specification is few, and production cost is high, and cable weight is large, and not flexible, during installation, joint is many, takes up room large.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of high-strength flexible fire-resisting cable, be applicable in the power supply-distribution system of the high flame retardant requirement such as cable trough, cable shaft, tunnel, be specially adapted to the place that there are low cigarette, Halogen, flame-retardancy requirements in school, market, government organs etc.
The technical solution of the utility model is as follows:
High-strength flexible fire-resisting cable, it is characterized in that, comprise many conductors, every root conductor is coated with flame retardant coating all successively outward and silicone rubber insulation layer forms insulated wire cores, many insulated wire cores annular space arrange formation cable core, cable core center is provided with braided steel wire cylinder, cable core extrusion moulding is in low-smoke halogen-free flame-resistant polyolefin oxygen barrier, low-smoke halogen-free flame-resistant polyolefin oxygen barrier to be two-layerly made up of inside and outside, inside and outside two-layer between be provided with refractory glass fibre braid, low-smoke halogen-free flame-resistant polyolefin oxygen barrier is coated with lapping layer outward successively, reinforced layer, belting layer, low smoke halogen-free flame-retardant polyolefin external sheath layer is extruded with outside belting layer.
Described high-strength flexible fire-resisting cable, is characterized in that, described flame retardant coating adopts the wrapped formation of synthetic mica tape, and wrapped rate of putting up generally is not less than 32%.
Described high-strength flexible fire-resisting cable, is characterized in that, described low-smoke halogen-free flame-resistant polyolefin oxygen barrier thickness is generally 0.12 ~ 01.25mm.
Described high-strength flexible fire-resisting cable, is characterized in that, the inner covering that described reinforced layer adopts mineral material extrusion molding to form is formed around steel wire with dredging, and dredges and is wrapped in inner covering around steel wire spiral.
The utility model has the advantages that:
The utility model novel in structural design, be applicable in the power supply-distribution system of the high flame retardant requirement such as cable trough, cable shaft, tunnel, be specially adapted to the places such as school, market, government organs, have excellent low cigarette, Halogen, flame retardant effect, resistance to elevated temperatures, mechanical performance are remarkable.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
High-strength flexible fire-resisting cable, comprise many conductors 1, every root conductor 1 is coated with flame retardant coating 2 all successively outward and silicone rubber insulation layer 3 forms insulated wire cores, many insulated wire cores annular space arrange formation cable core, cable core center is provided with braided steel wire cylinder 4, cable core extrusion moulding is in low-smoke halogen-free flame-resistant polyolefin oxygen barrier 5, low-smoke halogen-free flame-resistant polyolefin oxygen barrier is by inside and outside two-layer 5-1, 5-2 is formed, inside and outside two-layer 5-1, refractory glass fibre braid 6 is provided with between 5-2, low-smoke halogen-free flame-resistant polyolefin oxygen barrier 5 is outer is coated with lapping layer 7 successively, reinforced layer 8, belting layer 9, low smoke halogen-free flame-retardant polyolefin external sheath layer 10 is extruded with outside belting layer 9.
Flame retardant coating 2 adopts the wrapped formation of synthetic mica tape, and wrapped rate of putting up generally is not less than 32%.
Low-smoke halogen-free flame-resistant polyolefin oxygen barrier 5 thickness is generally 0.12 ~ 01.25mm.
The inner covering 8-1 that reinforced layer 8 adopts mineral material extrusion molding to form is formed around steel wire 8-2 with dredging, dredging is wrapped in inner covering 8-1 around steel wire spiral, after inner covering is extruded onto certain thickness, dredge after steel wire 8-2 spiral winding again extrusion molding certain thickness form whole inner covering 8-1.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
