Description
Technical field
This utility model relates to power cable field, refers in particular to a kind of reinforced fire-resistant high tension cable.
Background technology
Along with important places such as the quickening of China's economic construction paces, skyscraper, subway, power plant, nuclear power station, tunnels
Intermediate distribution system, cable safety under Fire Conditions is had higher requirement, then in pressure fire-resisting cable should
Fortune is looked unfamiliar, but due to the special electrical performance demands of midium voltage cable, it is impossible to use the general mode of production of low pressure fire-resisting cable,
Needing to use a kind of special mode of production, this causes middle pressure fire-resisting cable physical dimension bigger than normal, makes troubles to laying installation,
For this situation, according to the feature of 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, in conductor, the insulation of cable
It is surrounded with outward fire-resistant isinglass belt, and outside cable core, is also surrounded with mica tape；2, using copper sheath magnesium oxide insulated mode, this is
A kind of outer layer uses seamless copper pipe sheath, middle filling magnesia crystal powder to make insulant, and conductor is sub-thread copper rod composition
Novel cable.The material of cable is all inorganic matter, without any can combustion-supporting medium it have high temperature resistant, fire prevention, do not burn and current-carrying
Amount 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 should
Class cable is medium-pressure power cable, and its special electrical performance demands core must be by conductor wire core, conductor shielding, XLPE insulation
With 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 protect
Demonstrate,prove 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.
Utility model content
Technical problem to be solved in the utility model there is provided a kind of good flame resistance, fire resistance is good and can automatically drop
The reinforced fire-resistant high tension cable of temperature.
The reinforced fire-resistant high tension cable of one described in the utility model, including cable core, described cable core is thoroughly done away with edge by three
Core is stranded to be formed；At the gap filling glass silk of cable core, it is the composite flame-proof of 0.5-1.5mm at cable core outer cladding thickness
Band, extrudes the PVC inner liner that thickness is 2.35-4.75mm outside composite flame-proof band, being externally provided with thickness at inner liner is the soft of 1-2cm
Water pipe, hose is externally provided with the metal armor layers that thickness is 3-6mm, and metal armor layers is externally provided with outside the PVC that thickness is 2-4mm and protects
Set；Water inlet and apopore it is provided with in described hose.
Improve further, described insulated wire cores by steel wire strengthening core, the aluminium alloy conductor that is located at outside steel wire strengthening core with
And the glass tape that the thickness being extruded in outside aluminium alloy conductor is 2-4mm is constituted.
Improving further, described composite flame-proof layer is three-decker, and upper strata is the glass fibre of thickness 1.55-2.55mm
Band, 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 utility model are:
1, this utility model is provided with glass fiber, will not burn, and will not produce harmful substance, can play very well during cable fire
Fire retardation, and life-time service does not haves powder phenomenon-tion.
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, and any has even if also will not produce under flame condition
Evil gas, 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 works as electricity
Cable burns in high temperature, and water ejects reduction from apopore or extinguishes fire, it is ensured that other layers are not burned, it is ensured that the normal work of cable
Make.
5, this utility model has the strongest reinforcing property and from load-carrying properties, the conductor central layer You Yigen center of cable
Strengthening core, the stress point of conductor concentrates on the strengthening core of center, and cable, in folding and unfolding winding process, protects conductor, and not
Frangibility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of composite flame-proof layer of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of reinforced fire-resistant high tension cable of this utility model, including cable core, described cable core is by three
