Description

A kind of super flame-retardant environment protection type high pressure power cable of superelevation suspension type
Technical field
This utility model is related to a kind of Cable Construction Design, a kind of super flame-retardant environment protection type high pressure electric power of superelevation suspension type Cable Construction Design belongs to field of cable technology.
Background technology
With the development of China's economy and science and technology, the increase of population density.High-rise, high-rise building is gradually prevailing, And high-rise, high-rise building constantly breaks through new height.Used as the terrestrial reference in modern city, high-rise building has shown non- All effects, become country, the symbol of national and urban economy emergence.Because building interior is powered according to power load center, In order to reduce the occupancy of building interior space, so electric substation is distributed into design in the high-rise diverse location in building, change Past only substantially reduces low tension cable power supply path by the traditional approach of low-voltage power supply system, reduces line loss, also changes Power quality has been apt to it, it can be ensured that building power supply safety reliability.In order to avoid there is polylinker in the middle of cable, and hang down Straight section is limited because of hoistway space, only can be fixed on vertical derrick, so cable has to hanging installation.
In this regard, super fire-retardant, the super fire resisting environment-friendly type high voltage power cable of superelevation suspension type of my company's exploitation.Because cable is applied Wiring located between the electric substation that normal throw is big, horizontal displacement is little, so the performance of high tensile should be met, and high-rise, High-rise building population concentration, density is larger.In order to avoid there is fire, casualties and property loss, the cable are reduced High fire-retardance, fire resisting, Halogen, low cigarette etc. can be met extremely to require.
We develop super fire-retardant, the super fire resisting environment-friendly type high voltage power cable of superelevation suspension type have high fire-retardance, high fire resisting, The characteristics such as high tensile, environmental protection, the reasonable structure of product are improved while product electric property, mechanical performance is met, are stablized Property, to improve cable-flame retardant with fire-resistance property and the service life of product.
The content of the invention
Wiring to meet that normal throw is big, between the electric substation that horizontal displacement is little and have developed a kind of superelevation suspension type and surpass Fire-retardant, super fire resisting environment-friendly type high voltage power cable.
This utility model technology is achieved through the following technical solutions:Core is to be followed successively by conductor, conductor from inside to outside Shielding, insulation, insulation shielding, metal screen layer constitute core, and High-strength environmentally-friefuran fire proofing cladding galvanized strand wires structure Into sector structure lifting core as filling stranding, after stranding from inside to outside successively by band, oxygen barrier layer, cooling layer, flame retardant coating, Band, oversheath are constituted.
The insulation uses ultra-clean water resistant tree-shaped crosslinked polyethylene insulation material, can pass the cable through 17500 hours Middle pressure water resistant tree test.
The conductor shield using not peelable type ultra-smooth crosslinking semiconductive shieldin material, with ensure conductor shielding with it is exhausted Edge contact surface is smooth, is further ensured that its excellent electrical property.
The insulation shielding is crosslinked semiconductive shieldin material using peelable type ultra-smooth, is easy to while electrical property is ensured The installation of joint during cable construction.
The structure that the metallic shield is shielded using split-phase, and overlapped around packet form using monolayer copper strips, to ensure cable High electrical-magnetic compatibility and low electromagnetic susceptibility during use.
Described oxygen barrier layer, cooling layer, the compound flame-retardant layer of flame retardant coating composition, it is ensured that cable has high fire-retardance, height The performance of fire resisting.
Outermost layer is flame retardant coating, using the macromolecule polymer material with fire resistance or inorganic refractory mud material, in quilt In the case of flame ablation, flame retardant coating can crust within the extremely short time, change into hard ceramic-like material, and one layer of formation is good Good isolation layer, on the one hand can prevent spreading for flame, on the other hand can completely cut off the high temperature produced by flame combustion.
Secondary outer layer is cooling layer, and using the method for coating inorganic metal hydrate, the material is met and separate out after high temperature crystallization Water simultaneously resolves into metal-oxide, and metal-oxide absorption can form cavernous shell, this shell on flame retardant coating surface There is certain adsorption to flue gas, meanwhile, the moisture of precipitation can play a part of fully to lower the temperature flame retardant coating.
Innermost layer is oxygen barrier layer, using environmental-protection flame-retardant material, the water of crystallization that this material is produced after high temperature or burning Molecule, has played good heat-insulated, oxygen barrier effect, further enhancing the cooling protection to insulated wire cores.
Compound flame-retardant layer can effectively strengthen the flame-retardant performance of cable, it is ensured that cable energy under flame temperature Enough long-time normal works, improve the quality stability of cable.
This utility model product structure design innovative point:1st, cable is using the special High-strength environmentally-friefuran by softness for designing Fire proofing is extruded in galvanized strand wires and strengthens wicking surface and into corrugated type structure, it is ensured that cable cabling is substantial tight rounding 's.Can ensure the environmental requirement of cable from soft High-strength environmentally-friefuran fire proofing, can prevent from being filled in stranding again The phenomenon of cable rounding occurs that stand up, distort etc. and is unfavorable in bar.From high intensity galvanized strand wires as cable strengthening core, The minimum Fracture Force of arbitrary galvanized strand wires is both greater than the gravity of the vertical lifting part of cable, so as to ensure that hanging for cable Dress safety.
Also, this design can ensure that when cable hoisting lays vertical component reduces the lateral pressure from galvanized strand wires, From fan-shaped plastic overmold galvanized strand wires strengthening core, the peripheral clearance of cable is filled in so that fan-shaped cambered surface and cable surface It is in close contact, such cable is subject to the lateral pressure of steel wire rope, can be dispersed in the surface of cable, is not in stress concentration Phenomenon.
2nd, there are high fire resistant requirements in order to meet cable, employs the macromolecule polymer material with fire resistance or inorganic Flame retardant coating of the fire clay as cable.
The advantages such as the macromolecule polymer material of fire resistance, extrusion efficiency high, cycle is short, and the material also has Ceramic speed is fast and the characteristics of thermal insulation excellent performance, it is ensured that when cable is in flame, can be ceramic in cable surface in the short time Change, be wrapped in cable surface, prevent propagation of flame, isolation flame temperature.
Inorganic refractory mud have do not burn, not heat release, it is smokeless, without characteristics such as toxic gases, due to being inorganic mineral oxygen Compound, it has excellent heat-resisting quantity, and it is harsh that the formed ceramic armouring housing that burns can also bear spray, vibrations etc. Environmental requirement.Ensure that cable safely and effectively runs.
