Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-4, the utility model provides a kind of technical solution: a kind of flame-proof wire, including electric wire main body 1 and Protective jacket 2, protective jacket 2 are set in electric wire main body 1, be coated on the outside of protective jacket 2 insulating layer 3, armor 4, flame retardant coating 5 and Protective layer 6, insulating layer 3 are coated on 2 outside of conductor protective jacket, for completely cutting off conductor, bear corresponding voltage, prevent electric current from letting out Dew, armor 4 are coated on 3 outside of insulating layer, and for protecting conductor wire main body 1 not damaged by external force, flame retardant coating 5 is coated on armour Fill the outside of layer 4, be used for fire resisting, protect electric wire main body 1, protective layer 6 is coated on 5 outside of flame retardant coating, for protect flame retardant coating 5 not by External force damage, if 6 outer sheath of protective layer is equipped with the identical fire extinguishing ball 7 of stem structure, several fire extinguishing balls 7 are installed along appointed interval in anti- On sheath 2, flame retardant coating 5 is used for fire resistant flame retardant, insulating layer 3 and armour using irradiated crosslinking low-smoke and halogen-free material integrated formed structure is exempted from Be installed on filled layer 8 between dress layer 4, filled layer 8 uses non-hygroscopic insulation system, for allowing cable rounding, to insulating layer 3 into Row protection, fire extinguishing ball 7 are ring cavity structure, and fire extinguishing ball 7 and protective jacket 2 use integrated formed structure, be placed in fire extinguishing ball 7 Fire extinguishing soil, for fire-retardant, armor 4 uses wire quality reticular structure, resistance to for protecting electric wire main body 1 not damaged by external force Fire bed 5 can also coat armor 4 using mica tape 9, for fire resisting, fire-retardant.

Embodiment: by Figure of description 1-3 it is found that this case is a kind of flame-proof wire, including electric wire main body 1 and protective jacket 2, protective jacket 2 is set in electric wire main body 1, and insulating layer 3, armor 4, flame retardant coating 5 and protective layer are coated on the outside of protective jacket 2 6, and positional relationship and connection relationship are as follows:

Insulating layer 3 is coated on 2 outside of conductor protective jacket, for completely cutting off conductor, bears corresponding voltage, prevents electric current from letting out Dew, armor 4 are coated on 3 outside of insulating layer, and for protecting conductor wire main body 1 not damaged by external force, flame retardant coating 5 is coated on armour Fill the outside of layer 4, be used for fire resisting, protect electric wire main body 1, protective layer 6 is coated on 5 outside of flame retardant coating, for protect flame retardant coating 5 not by External force damage, if 6 outer sheath of protective layer is equipped with the identical fire extinguishing ball 7 of stem structure, several fire extinguishing balls 7 are installed along appointed interval in anti- On sheath 2；

By above-mentioned it is found that when in use, when fire behavior occurs for outside, high temperature flare toasts protective layer 6, works as protection 6 burning of layer falls off, and by direct baking flame retardant coating 5, flame retardant coating 5 is integrally formed high temperature flare using irradiated crosslinking low-smoke and halogen-free material is exempted from Structure more facilitates fire resistant flame retardant, and can just Internal cable be carried out brokenly only after flame retardant coating 5 falls off by extending fire resistance period It is bad, the power-on time under the state of emergency is substantially prolonged, so that the fire line of electric wire main body 1 can be promoted, if while occurring Be cable itself since load excessive generates auto-ignition, when flame combustion to 7 position of fire extinguishing ball, fire extinguishing ball 7 is destroyed, Fire extinguishing soil built in it will carry out covering fire extinguishing or sluggish flame mechanism to the open fire on cable, when striving for for rescue work Between.

Preferably, further, filled layer 8 is installed between insulating layer 3 and armor 4, filled layer 8 uses Non-hygroscopic insulation system protects insulating layer 3 for allowing cable rounding.

Preferably, further, fire extinguishing ball 7 is ring cavity structure, and fire extinguishing ball 7 and protective jacket 2 use one Forming structure is placed with fire extinguishing soil in fire extinguishing ball 7, for fire-retardant.
