[background technology]
At present, the fireproof cable using on market have rigidity with flexible two kinds, these two kinds of cables are all using magnesium oxide as insulation, wherein rigidity fireproof cable coated outside copper pipe and is pressed and form through multiple tracks drawing procedure; Flexible fire-proof cable rolls into spiral-shaped outward at rigidity cable copper tube.Rigidity fireproof cable is first generation product, and flexible fire-proof cable is second generation product.These two kinds of cables have been applied for many years in market, but along with era development and scientific and technological progress, this cable of the prior art can not meet the demand of modernization development, as the multicore big-length cable demand in the places such as skyscraper, tunnel, airport increases day by day, these places all require the cable fire time long, and by original old explained hereafter, cannot meet modern demand.In prior art, the technology of product also has the following disadvantages: 1, not long with the cable length of original explained hereafter.2, cable quality is brought very inconvenient to construction firmly.3, Cable Bending Radius is little, because interior insulation is that magnesium oxide presses and forms, easily causes interior insulation cracking when bending.4, multicore electric cable with large cross-section can not stranding in one, can only two cores are single lay, while taking a lot of work, taken again installing space.5, skin makes in sheath of copper material parcel, consumes again a large amount of non-ferrous metals, has greatly increased cable deadweight and cost, has increased cost of transportation simultaneously.6, refractory temperature can only reach the defect such as 750 degree, 90 minutes time.
[utility model content]
The purpose of this utility model is exactly in order to solve cable length in prior art, quality, bending radius, deficiency and the defects such as weight etc. cannot satisfy the demands, a kind of novel structure is provided, safe and reliable, can meet the soft compression-resistant fire cable of clean spy of length and fire prevention demand, it is characterized in that described fireproof cable comprises conductor, conductor adopts the some multiple fire-proof and water-proof insulation material layers of conductor outer wrapping described in stranded the forming of copper wire, described multiple fire-proof and water-proof insulation material layer is from inside to outside followed successively by: fire lagging 2, separator 3, insulating waterproof layer 4, fire prevention packed layer 5, flame retardant bed 6.
Described flame retardant bed is provided with metal resistance to compression layer 7 outward.
Described flame retardant bed is provided with clean restrictive coating 8 outward, and described clean restrictive coating adopts nonmetallic materials.
Described flame retardant bed is provided with metal resistance to compression layer 7 outward, and metal resistance to compression layer is provided with clean restrictive coating 8 outward, and described clean restrictive coating adopts nonmetallic materials.
Described fire lagging is made up of more than four layers or four layers fire proofing materials, and described fire proofing material is mica tape.
Described separator is made up of fire-retardant alkali-free glass fibre band.
Described insulating waterproof layer is made up of heat insulation low-smoke bittern-free highly fire-proof material.
The filler of described fire prevention packed layer is ceramic fiber cotton.
Described flame retardant bed is high temperature resistance and high strength carbon fiber or ceramic fibre strip.
Described metal resistance to compression layer is zinc-coated wire belt.
Compared with the existing technology, its advantage is the utility model:
1, clean spy soft compression-resistant fire cable production length of the present utility model is long.
2, the pliability of cable quality is good, cable radius bend degree is large.
3, can be from two cores to five core strandings in a cable, multicore is integral, and the outside diameter of cable is little lightweight, and easily mounting and installation and bending, save a large amount of manpower and materials and installing space.
4, because fireproof cable skin of the present utility model makes in sheath of nonmetal object, saved greatly non-ferrous metal copper material and production cost, saved freight simultaneously and labour cost is installed.
5, cable fire temperature of the present utility model reaches 1200 degree, and fire resistance period reaches 180 minutes.
