Abstract
An interlocking armored flame-retardant cable comprises a protective layer, wherein at least one cable core is arranged in the protective layer, and an insulating sleeve and a sheath are coated outside each cable core in a built-in manner; the protective layer is an interlocking armature; the protective layer is formed in the way that an aluminium alloy belt in the thickness of 0.5mm-1.0mm is rolled by a die to form a closed interlocking lock catch in a wrapping manner; and the insulating sleeve is formed by wrapping flame-retardant plastics or a high-performance mica tape. The cable can meet flame-retardant and insulating properties, separates the flame from being in contact with internal insulating materials, can not be further burned under the condition of flames, ensures the normal power supply capability in a certain time span and improves the flame-retardant effect; and meanwhile, better bearing longitudinal pulling force and impact are provided, as well as better bendability, so that the cable during laying and use is prevented from being damaged.
Description
Technical field
The utility model relates to a kind of electric wire, refers in particular to a kind of lock armo flame retardant cable.
Background technology
The tradition flame retardant cable adopts and improves the material oxygen index, and protective layer quantity realizes flame retardant effect in the increase construction of cable, and special occasions adopts sheath structures such as copper, aluminum pipe.Thus, though fire resistance be largely increased, production cost of products, the installation laid condition of the complexity of technology, cable etc. has received very big restriction.
The utility model content
The purpose of the utility model is to provide a kind of lock armo flame retardant cable that can effectively simplify technology, reduce production costs.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of lock armo flame retardant cable comprises protective layer, is provided with at least one cable core in the said protective layer, and each cable core is coated with insulating case and sheath by built-in outer being provided with, and wherein, said protective layer is a lock armo.
Further, said protective layer is a 0.5mm-1.0mm thickness aluminum alloy strip, and is wrapped and form the interlocking snap close of sealing after mould is rolling.
Further, insulating case is the insulating case that flame retardant plastics is processed.
In addition, said insulating case also can adopt the wrapped one-tenth insulating case of high-performance mica tape.
The utility model can satisfy fire-retardant and insulation property; And make flame can't touch inner insulation material, guarantee cable flame-retarding power and in the regular hour, keep the ability of normal power supply not under flame condition, improved the effect of flame retardant cable; Simultaneously; Also have and bear longitudinal pulling force and impulsive force and reasonable bending property preferably, can guarantee cable lay with use in escape injury.
Description of drawings
Accompanying drawing 1 is the structure chart of the utility model;
Accompanying drawing 2 is the structure chart of lock armo.
Embodiment
Existing with reference to accompanying drawing, further explain the utility model.
Like accompanying drawing 1, a kind of lock armo flame retardant cable comprises protective layer 1, is provided with at least one cable core 11 in the protective layer 1, and each cable core 11 is coated with insulating case 12 and sheath 13 by built-in outer being provided with, and wherein, protective layer 1 is a lock armo.
With reference to accompanying drawing 2; Protective layer is a 10.5mm-1.0mm thickness aluminum alloy strip; It is wrapped and form the interlocking snap close of sealing after mould is rolling; Make flame can't touch inner insulation material, guarantee cable flame-retarding power and in the regular hour, keep the ability of normal power supply not under flame condition, improved the effect of flame retardant cable.
Wherein, different according to the flame-retardant class requirement, insulating case is insulating case or the wrapped one-tenth insulating case of high-performance mica tape that flame retardant plastics is processed, to satisfy fire-retardant and insulation property.
Simultaneously; The cable sheath structure of lock armo; Can bear 60kg pulling force (disconnecting easily when common band-armored bears longitudinal pulling force) and 1.0 meters impulsive forces of 5kg weight; Bending radius can reach 7 times of outside diameters of cable (common armoured cable bending radius is greater than 12 times, and copper, aluminum pipe sheath cable are difficult to bending), above performance can guarantee cable lay with use in escape injury.
Above-described the utility model execution mode does not constitute the qualification to the utility model protection range.The modification of being done within any spirit and principle at the utility model, be equal to replacement and improvement etc., all should be included within the claim protection range of the utility model.
Claims (4)
