Description
Technical field
The present invention relates to power cable field, refer in particular to a kind of reinforced fire-resistant high tension cable.
Background technology
Quickening along with China's economic construction paces, skyscraper, subway, power plant, nuclear power station, the intermediate distribution system of the important places such as tunnel, cable safety under Fire Conditions is had higher requirement, then in, pressure fire-resisting cable meets the tendency and looks unfamiliar, but due to the electrical performance demands that midium voltage cable is special, the general mode of production of low pressure fire-resisting cable can not be used, need to use a kind of special mode of production, this causes middle pressure fire-resisting cable physical dimension bigger than normal, make troubles to laying installation, for this situation, feature according to middle pressure fire-resisting cable, existing structure design is optimized.
Existing fire-resisting cable, in order to improve its refractory ability, mainly has following several form: 1, be surrounded with fire-resistant isinglass belt outside the conductor, insulation of cable, and be also surrounded with mica tape outside cable core；2, using copper sheath magnesium oxide insulated mode, this is that a kind of outer layer uses seamless copper pipe sheath, middle filling magnesia crystal powder to make insulant, and conductor is the novel cable of sub-thread copper rod composition.The material of cable is all inorganic matter, without any can combustion-supporting medium it there is high temperature resistant, fire prevention, do not burn and current-carrying capacity is big, external diameter is little, mechanical strength is high, service life is long, typically need not the feature of independent grounding wire.
The problems and disadvantages that prior art exists:
When using above-mentioned first kind of way, owing to being provided with refractory material outside the conductor of cable, insulation, but such cable is medium-pressure power cable, its special electrical performance demands core must by conductor wire core, conductor shielding, XLPE insulation and insulation shielding, metallic shield etc. form, when there being the intervention of refractory material, hence it is evident that affect cable current-carrying capacity, in order to ensure its current-carrying capacity, need to increase ground A Lan conductors cross so that the outside diameter of cable do relatively big, and Heavy Weight.
Summary of the invention
The technical problem to be solved there is provided the reinforced fire-resistant high tension cable that a kind of good flame resistance, fire resistance are good and can automatically lower the temperature.
The reinforced fire-resistant high tension cable of one of the present invention, including cable core, described cable core is formed by three insulated wire cores are stranded；Gap filling glass silk at cable core, at the composite flame-proof band that cable core outer cladding thickness is 0.5-1.5mm, the PVC inner liner that thickness is 2.35-4.75mm is extruded outside composite flame-proof band, it is externally provided with the hose that thickness is 1-2cm at inner liner, hose is externally provided with the metal armor layers that thickness is 3-6mm, and metal armor layers is externally provided with the PVC oversheath that thickness is 2-4mm；Water inlet and apopore it is provided with in described hose.
Improve further, aluminium alloy conductor that described insulated wire cores by steel wire strengthening core, is located at outside steel wire strengthening core and be extruded in the glass tape that the thickness outside aluminium alloy conductor is 2-4mm and constitute.
Improving further, described composite flame-proof layer is three-decker, and upper strata is the glass fiber tape of thickness 1.55-2.55mm, and centre is the flame retardant rubber band of thickness 2.55-3.55mm, and lower floor is the fire-retardant rock wool belt of thickness 1.55-2.55mm.
The beneficial effects of the present invention is:
1, the present invention is provided with glass fiber, will not burn, and will not produce harmful substance, can play good fire retardation, and life-time service does not haves powder phenomenon-tion during cable fire.
2, conductor is externally provided with glass tape, preferably protects conductor and is not burned.
3, the inner sheath of cable is that metallic aluminium is made, and will not burn, even if also will not produce any harmful gas under flame condition, and ensure that other layers in cable are not burned.
4, being provided with hose in cable, in water pipe, there is water the inside, and is added by water inlet and apopore and discharge, and when cable burns in high temperature, water ejects reduction from apopore or extinguishes fire, it is ensured that other layers are not burned, it is ensured that cable normally works.
5, the present invention has the strongest reinforcing property and from load-carrying properties, and the conductor central layer You Yigen center strengthening core of cable, the stress point of conductor concentrates on the strengthening core of center, and cable, in folding and unfolding winding process, protects conductor, and is not easily broken.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of the composite flame-proof layer of the present invention.
Detailed description of the invention
As it is shown in figure 1, a kind of reinforced fire-resistant high tension cable of the present invention, including cable core, described cable core is formed by three insulated wire cores are stranded；Aluminium alloy conductor 2 that described insulated wire cores by steel wire strengthening core 1, is located at outside steel wire strengthening core and the glass tape that thickness is 2-4mm 3 being extruded in outside aluminium alloy conductor are constituted；
Then, gap filling glass silk 4 at cable core, at the composite flame-proof band 5 that cable core outer cladding thickness is 0.5-1.5mm, the PVC inner liner 6 that thickness is 2.35-4.75mm is extruded outside composite flame-proof band 5, it is externally provided with the hose 7 that thickness is 1-2cm at inner liner, hose is externally provided with the metal armor layers 8 that thickness is 3-6mm, and metal armor layers is externally provided with the PVC oversheath 9 that thickness is 2-4mm；Water inlet 10 and apopore 11 it is provided with in described hose.
