Abstract
The utility model relates to a high performance metal sheath inorganic mineral insulation flexible fireproof cable comprising a conductor, an outer part of which is provided with an inorganic mineral insulation layer. An outer part of the inorganic mineral insulation layer is provided with a ripple-shaped metal sheath, an outer part of which is provided with a low smoke halogen free outer sheath. The cable provided in the utility model has advantages of excellent fireproof performance, good integral flexibility, safety, environmental protection, good anti-corrosion performance, convenient installation, and simple production.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of fireproof cable.
Background technology
Along with industrialization urbanization process accelerate, all kinds of fire incidents are frequent occurrence also, causes the massive losses of lives and properties.And along with the raising of fire-fighting consciousness, developed country must select fireproof cable according to different purposes at the electric distribution line of a part.Domestic power department is also promoted the use of fireproof cable in 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 occured, common fire prevention fire control cable processed can't guarantee that circuit works on, and was difficult to strive for time of more growing for escape and rescue.A kind of magnesium oxide fireproof cable is arranged on the market, in actual use, have following problem: at first it is not suitable for mobile occasion, and copper pipe in a single day damaged insulation property 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 owing to the easy moisture absorption of magnesium oxide insulated, and cable is vertically moistureproof to be required and avoid the metallic sheath damage especially to seem important, and employing fluid sealant in 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 also very difficult, often because of the joint water inlet, causes insulation resistance defective.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of fire protecting performance superior, and whole cable is better flexible, safe and environmentally friendly, good corrosion resistance, easy for installation, make simple high-performance 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 high-performance metal sheath inorganic mineral insulation flexible fire-proof cable described in the utility model, it comprises conductor, be provided with the inorganic mineral insulation layer in described conductor outside, be provided with corrugated metal sheath in described inorganic mineral insulation layer outside, be provided with the low smoke, zero halogen oversheath in described corrugated metal sheath outside.
Described conductor is copper conductor, and forms by the multiply annealed copper wire is stranded, thereby soft pliable is bent more.
Described conductor is single core or more than two cores.
Described corrugated metal sheath is corrugated copper sheath, and described corrugated copper sheath adopts copper strips to be welded copper strips non junction between unit cable length.
When the utility model 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 utility model compared with prior art, its remarkable advantage is: the utility model is simple in structure, adopt inorganic mineral insulation layer and low smoke, zero halogen oversheath, greatly improved whole fire protecting performance, do not produce any pernicious gas during burning, it is a kind of environment-friendly and green product, adopt corrugated metal sheath and low smoke, zero halogen oversheath, can effectively bear water spray and mechanical impact, adopt the stranded conductor of making of multiply annealed copper wire, increased the flexibility of whole cable, cable adopts metallic sheath, does not need poling, and is easy for installation, and the metallic sheath good corrosion resistance, whole manufacturing cost is lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, conductor; 2, inorganic mineral insulation layer; 3, corrugated metal sheath; 4, low smoke, zero halogen oversheath
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.As shown in Figure 1, a kind of high-performance metal sheath inorganic mineral insulation flexible fire-proof cable described in the utility model, it comprises conductor 1, be provided with inorganic mineral insulation layer 2 in described conductor 1 outside, be provided with corrugated metal sheath 3 in described inorganic mineral insulation layer 2 outside, be provided with low smoke, zero halogen oversheath 4 in described corrugated metal sheath 3 outsides; Described conductor 1 is copper conductor, and forms by the multiply annealed copper wire is stranded; Described conductor 1 is single core or more than two cores; Described corrugated metal sheath 3 is corrugated copper sheath.The utility model is simple in structure, adopt inorganic mineral insulation layer and low smoke, zero halogen oversheath, greatly improved whole fire protecting performance, do not produce any pernicious gas during burning, it is a kind of environment-friendly and green product, adopt corrugated metal sheath and low smoke, zero halogen oversheath, can effectively bear water spray and mechanical impact, adopt the stranded conductor of making of multiply annealed copper wire, increased the flexibility of whole cable, cable adopts metallic sheath, do not need poling, easy for installation, and the metallic sheath good corrosion resistance, whole manufacturing cost is lower.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away 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, in the present embodiment not clear and definite each part all available prior art realized.
