The low smoke zero halogen (LSOH) anticorrosion cable will not generate toxic gas and heavy smoke containing halogen under fire hazard environment, and is environment friendly; and the cable has good anticorrosion performance and electrical performance, is fireproof and high temperature resistant, and has strong power supply capability under fire hazard environment.
Description
Technical field
The utility model relates to cable, is specifically related to a kind of low smoke and zero halogen anticorrosion cable.
Background technology
Current, in the common low-voltage power system, generally adopt common crosslinked polyetylene insulated wire armoring pvc sheath power cable.The weak point of this type cable is: water resistance is relatively poor, steel wire is corroded easily, and the resistance to corrosion of pvc sheath is not strong, and, this cable if blaze up, can produce a large amount of Halogen toxic gases and dense smoke when breaking out of fire, both influenced the carrying out of rescue and relief work, even related personnel's personal safety had been produced fatal threat.
The utility model content
The purpose of this utility model is: overcome the deficiencies in the prior art, by the improvement on the structure and material, provide a kind of smog that produces under fire hazard environment low smoke and zero halogen anticorrosion cable few and not strong with halogen toxin, resistance to corrosion, good electric property.
The technical solution of the utility model is: low smoke and zero halogen anticorrosion cable of the present utility model comprises conductor, fireprotection layer, insulating barrier, steel-tape armouring layer and external sheath layer; The wrapped periphery of above-mentioned fireprotection layer at conductor, insulating barrier is extruded in the periphery of fireprotection layer; Its design feature is: also comprise spring coil protective layer and inner covering; Above-mentioned conductor is the tin-coated copper conductor; Fireprotection layer is 6 laminated one-tenth mica tape fireprotection layers; Insulating barrier is the IXPE insulating barrier; Above-mentioned spring coil protective layer is formed by the spiral periphery that is wrapped in insulating barrier of the non-magnetic stainless steel silk of 1.5～2mm diameter, and the gap between screw of stainless steel wire is that 1～1.5 times steel wire diameter, surface of stainless steel wire is coated with the high temperature resistant heat insulation material of being made up of nano ceramics particulate and silicate compound; Inner covering is coated on the thermal insulation layer of the periphery of spring coil protective layer for the high flame-retardant cable material extruding of being made of aluminium hydroxide and magnesium hydroxide mixture; Above-mentioned steel-tape armouring layer is arranged on the periphery of inner covering; Above-mentioned external sheath layer is the low-smoke halogen-free polyolefin restrictive coating; External sheath layer is coated on the periphery of steel-tape armouring layer.
The utlity model has positive effect: (1) low smoke and zero halogen anticorrosion of the present utility model cable, owing to adopt the mica band not burn, so under fire hazard environment, can not produce toxic gas and smog, simultaneously, external sheath layer adopts the polyolefin overcoat of low smoke, zero halogen, it can not produce halogen-containing toxic gas and dense smoke under fire hazard environment, environmental-protecting performance is good.(2) low smoke and zero halogen anticorrosion cable of the present utility model by adopting zinc-plated copper conductor, has improved the Corrosion Protection and the electric property of cable.(3) low smoke and zero halogen anticorrosion cable of the present utility model by spring coil protective layer and inner covering are set, thereby is significantly strengthened fire-resistant, the resistance to elevated temperatures of cable, has improved power supply capacity under the fire hazard environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Reference numeral in the above-mentioned accompanying drawing is as follows:
Inner covering 5, steel-tape armouring layer 6, external sheath layer 7.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
(embodiment 1)
See Fig. 1, the low smoke and zero halogen anticorrosion cable of present embodiment is made up of conductor 1, fireprotection layer 2, insulating barrier 3, spring coil protective layer 4, inner covering 5, steel-tape armouring layer 6 and external sheath layer 7.
The material of spring coil protective layer 4 is the non-magnetic stainless steel silk of 1.5～2mm diameter, and surface of stainless steel wire is coated with the high temperature resistant heat insulation material of being made up of nano ceramics particulate and silicate compound; The spiral periphery that is wrapped in insulating barrier 3 of stainless steel wire, the gap between screw of stainless steel wire is 1～1.5 times a steel wire diameter.Spring coil protective layer 4 is set, insulating barrier 3 is not contacted with the outer insulative layer of cable, effectively reduce the efficient that outside heat is inwardly transmitted under the cable heated situation.
The material of inner covering 5 is the high flame-retardant cable material that aluminium hydroxide and magnesium hydroxide mixture are formed, and inner covering 5 extruding are coated on the periphery of spring coil protective layer 4.When the cable heated temperature reached more than 240 degrees centigrade, aluminium hydroxide, magnesium hydroxide began to decompose successively, and the hydrone that produces in the decomposable process plays the fire-retardant effect of oxygen barrier.
Steel-tape armouring layer 6 adopts existing steel-tape armouring layer, and steel-tape armouring layer 6 is arranged on the periphery of inner covering 5.
The material of external sheath layer 7 selects for use the low-smoke halogen-free polyolefin material to make, and external sheath layer 7 is coated on the periphery of steel-tape armouring layer 6.
The low smoke and zero halogen anticorrosion cable of present embodiment, owing to adopt the mica band not burn, so under fire hazard environment, can not produce toxic gas and smog, simultaneously, external sheath layer 7 adopts the polyolefin overcoat of low smoke, zero halogen, it can not produce halogen-containing toxic gas and dense smoke under fire hazard environment, environmental-protecting performance is good; By adopting zinc-plated copper conductor, improved the Corrosion Protection and the electric property of cable; Owing to be provided with spring coil protective layer 4 and inner covering 5, thereby fire-resistant, the resistance to elevated temperatures of cable significantly strengthened, improved power supply capacity under the fire hazard environment.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion and variation and obtain the corresponding technical scheme that is equal to, so all technical schemes that are equal to all should be included into scope of patent protection of the present utility model.
