The fireproof cable comprises a copper conductor; an inorganic mineral insulating layer is arranged outside the copper conductor; a corrugated metallic sheath is arranged outside the inorganic mineral insulating layer. The fireproof cable disclosed by the invention has excellent fireproof performance and good integral flexibility, is safe and environmental friendly, has good corrosion resistance, is convenient to install and simple to manufacture.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of fireproof cable.
Background technology
Along with industrialization urbanization process accelerate, all kinds of fire incidents also frequently take place, and cause the massive losses of lives and properties.And along with the raising of fire-fighting consciousness, developed country must select fireproof cable for use according to different purposes at the electric distribution line of a part.Domestic power department is also promoted the use of fireproof cable in the skyscraper and the public place of entertainment in city.
The sheath material of present common fireproof cable generally adopts polyvinyl chloride or crosslinked polyethylene.This cable is owing to its design feature, and refractory temperature is low, and fire-resistant reliability is not strong.When fire took place, common fire prevention fire control system cable can't guarantee that circuit works on, and was difficult to for escaping and rescuing the longer time of striving for.A kind of magnesia fireproof cable is arranged on the market; In actual use, have following problem: at first it is not suitable for moving occasion, and the in a single day damaged insulation property of copper pipe can descend rapidly; And insulation property can sharply descend under the high temperature, so should not adopt in a large number in the engineering; Secondly, this cable is the easy moisture absorption because magnesia insulate, and cable is vertically moistureproof to require and avoid the metallic sheath damage especially to seem important that fluid sealant is adopted in the termination, can have a strong impact on useful life; Moreover manufacturing process also limited the factory length of cable, causes that joint increases, and the water-proofing treatment of joint is difficulty very also, often because of the joint water inlet, causes insulation resistance defective.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of fire protecting performance superior in order to overcome deficiency of the prior art, and whole cable is better flexible; Safe and environmentally friendly; Good corrosion resistance, easy for installation, make simple metal sheath inorganic mineral insulation flexible fire-proof cable.
Technical scheme: in order to solve the problems of the technologies described above; A kind of metal sheath inorganic mineral insulation flexible fire-proof cable of the present invention; It comprises copper conductor, is provided with the inorganic mineral insulating barrier in said copper conductor outside, is provided with corrugated metal sheath in said inorganic mineral insulating barrier outside.
Said copper conductor forms by the multiply annealed copper wire is stranded, thereby soft pliable is bent more.
Said copper conductor is single core or more than two cores.
Said corrugated metal sheath is corrugated copper sheath, and said corrugated copper sheath adopts copper strips to be welded copper strips non junction between unit cable length.
When the present invention adopted multicore to make, its cross section was at 35mm
2During following specification, fill with alkali-free glass wool the gap, and its cross section is at 50mmm
2When specification was above, the whole sector structure that adopts need not filler.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: the present invention is simple in structure, adopts the inorganic mineral insulating barrier; Having improved whole fire protecting performance greatly, do not produced any pernicious gas during burning, is a kind of environment-friendly and green product; Adopt corrugated metal sheath, can effectively bear water spray and mechanical impact, adopt the stranded conductor of processing of multiply annealed copper wire; Increased the flexibility of whole cable, cable adopts metallic sheath, does not need poling; Easy for installation, and the metallic sheath good corrosion resistance, whole manufacturing cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein:
1, copper conductor; 2, inorganic mineral insulating barrier; 3, corrugated metal sheath
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in Figure 1, a kind of metal sheath inorganic mineral insulation flexible fire-proof cable of the present invention, it comprises copper conductor 1, is provided with inorganic mineral insulating barrier 2 in said copper conductor 1 outside, is provided with corrugated metal sheath 3 in said inorganic mineral insulating barrier 2 outsides; Said copper conductor 1 forms by the multiply annealed copper wire is stranded; Said copper conductor 1 is single core or more than two cores; Said corrugated metal sheath 3 is corrugated copper sheath.The present invention is simple in structure, adopts the inorganic mineral insulating barrier, has improved whole fire protecting performance greatly, does not produce any pernicious gas during burning; Be a kind of environment-friendly and green product, adopt corrugated metal sheath, can effectively bear water spray and mechanical impact, adopt the stranded conductor of processing of multiply annealed copper wire; Increased the flexibility of whole cable, cable adopts metallic sheath, does not need poling; Easy for installation, and the metallic sheath good corrosion resistance, whole manufacturing cost is lower.
The invention provides a kind of thinking and method, realize that specifically the method for this technical scheme and approach are a lot, the above only is a preferred implementation of the present invention; Should be understood that; For those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching; These improvement and retouching also should be regarded as protection scope of the present invention, and all available prior art of each part not clear and definite in the present embodiment realizes.
