Background technique
With the development of economy and science and technology in our country, the increase of the density of population, high level, super high-rise building are gradually prevailing,
And constantly break through new height.As the terrestrial reference in modern city, super high-rise building has shown outstanding effect, becomes state
The symbol that family, national and urban economy emerge.Since building interior is powered according to power load center, in order to reduce building
Electric substation's distribution is designed the different location in building high level by the occupancy of inner space.It changes over only by low-voltage power supply system
Traditional power supply mode of system, substantially reduces low tension cable power supply path, reduces line loss, also improve power quality,
It may insure building power supply safety reliability.In order to avoid that should not have polylinker among cable, and vertical section is because of hoistway sky
Between it is limited, cable design be hanging installation.
We develop super fire-retardant, the super fire resisting environment-friendly type high voltage power cable of superelevation suspension type with high fire-retardance, Gao Naihuo,
The characteristics such as high tensile, environmental protection improve reasonable structure, the stabilization of product while meeting product electric property, mechanical performance
Property, to improve the service life of cable-flame retardant Yu fire-resistance property and product.
Summary of the invention
It is a kind of according to skyscraper and super high-rise building the purpose of the present invention is in view of the above shortcomings of the prior art, providing
Space and the requirement of electric power system design and super fire-retardant, the super fire resisting environment-friendly type high-voltage electricity of a kind of superelevation suspension type developed
Power cable.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of super fire-retardant, super fire resisting environmental protection of superelevation suspension type
Type high voltage power cable, including insulated wire cores, compound flame-retardant layer, oversheath, the branch with LSOH anti-flaming performance
Support member, light high-intensity bundling belt, characterized in that the insulated wire cores include conductor, conductor shielding, insulation, insulation shielding, gold
Belong to shielding；The oversheath is halogen-free low-smoke polyolefine material；The supporting element of the LSOH anti-flaming performance is by soft
Property type high strength steel independent wire strand core wire rope outside extrude soft type halogen-free and low-smoke flame-retardant polyolefin composition；The light high-intensity bundling belt is
Finer wire, aramid fiber etc. weave.
It is overlapped wrapped high fire-retardance band outside insulated wire cores and extrudes oxygen barrier layer and flame retardant coating as compound flame-retardant layer, again
Mould assembly flame-retardant layer extrudes one layer of halogen-free and low-smoke flame-retardant polyolefin material as oversheath, and three have mutually isostructural cable
With the supporting element twisted synthesizing cable of LSOH anti-flaming performance, wrapped light high-intensity bundling belt on the outside of stranding cable core.
The core is shielded by conductor, the conductor shielding being extruded on the outside of conductor, cross-linking polyethylene materials insulating layer, insulation
It covers, metallic shield, high fire-retardance band, compound flame-retardant layer, oversheath composition.
The insulated wire cores are by three layers of conductor shielding, cross-linking polyethylene materials insulating layer, insulation shielding outside conductor, conductor
Co-extrusion is constituted.
The conductor is that T2 type copper monofilament is twisted.
The core is twisted gap and the supporting element with LSOH anti-flaming performance is used to fill.
Holding when the stranding result increases the supporting element with LSOH anti-flaming performance as cable right angle setting
Weight element.
It is described with Halogen, low cigarette, flame retardant property supporting element using soft type halogen-free and low-smoke flame-retardant polyolefin material and
High strength steel independent wire strand core wire rope.
The insulating layer, oxygen barrier layer, flame retardant coating, oversheath, filling are ep-type material.
The light high-intensity bundling belt is woven using finer wire, aramid fiber etc..
The soft type low smoke, zero halogen that the supporting element with Halogen, low cigarette, flame retardant property is independent wire strand and extrudes
The fan shape of fire retardant polyolefin.
Products innovation point of the invention is as follows:
1, structure innovation
Entire cable is designed around the performance of the use and safety and environmental protection that improve the installation of cable vertical lifting for objective.
First from the aspect of selection: 1) whole cable insulation, packing material, oxygen barrier layer, flame retardant coating and restrictive coating material
The material that material has selected crosslinked polyethylene and low smoke, zero halogen type ring to protect is effectively reduced in cable use process due to the feelings such as catch fire
When condition occurs, toxic gas is not distributed and is smokelessly distributed, guarantee cable environmental protection characteristic；2) cable has Halogen, low cigarette, anti-flammability
The supporting element of energy has selected independent wire strand and soft type LSOH anti-flaming material, tensile strength when both ensure that cable hoisting
Satisfaction, in turn ensure cable softness.3) the light high-intensity bundling belt on the outside of cable has selected finer wire, aramid fiber fine
Dimension etc. weaves, and both ensure that cable weight not will increase very much, in turn ensures that cable rounding will not be loose.
Secondly in structure design aspect: vertical lifting cable key is the selection of cable load bearing element, we have selected height
It extrudes outside intensity soft type independent wire strand and is constituted in arc-shaped sector Halogen, fire-retardant, low cigarette material, sector structure is filled in
It in cable cabling gap, is tightened by outermost high-intensitive bundling belt, ensure that cable has certain safe clearance and close
Structure.
2, function innovation
My company develops super fire-retardant, the super fire resisting environment-friendly type high voltage power cable of superelevation suspension type.Since cable laying is in vertical
Between the electric substation that drop is big, horizontal displacement is small, so the performance of high tensile should be met, and high-rise, super high-rise building population
It concentrates, density is larger.In order to avoid fire occurs, reduce casualties and property loss, cable should also have meet high fire-retardance,
The requirement of the safety and environmental protections performances such as fire resisting, Halogen, low cigarette.
We develop super fire-retardant, the super fire resisting environment-friendly type high voltage power cable of superelevation suspension type with high fire-retardance, Gao Naihuo,
The characteristics such as high tensile, environmental protection improve reasonable structure, the stabilization of product while meeting product electric property, mechanical performance
Property, to improve the service life of cable-flame retardant Yu fire-resistance property and product.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
