Abstract
The utility model discloses an aluminium alloy compacted conductor medium-voltage flame retardation fireproof cable comprising aluminium alloy compacted conductors; the conductor is wrapped by a shielding layer, an insulation layer, a shielding insulation layer and a metal shielding layer in sequence to form a wire core, and three wire cores are twisted to form a pair-twist cable core; the pair-twist cable core is wrapped by a taped covering1, a fireproof layer, a taped covering2 and a sheath layer in sequence; and a filling layer is arranged between the pair-twist cable core and the taped covering1. The fireproof layer is arranged outside the cable core, so flame cannot burn the conductors, and because of oxygen isolation and heat isolation effects of the fireproof layer, the heat cannot be conveyed to the cable core from outside to melt the aluminium alloy conductors, so the aluminium alloy conductors can be employed; compared with copper conductor, the aluminium alloy conductor is small in weight proportion, light in weight, cheap in price, and is rich in raw material resources; and because aluminium is a metal element with largest content in earth crust, so the aluminium alloy conductors can be employed to make fireproof cables so as to save vast copper and fund.
Description
Technical field
The utility model relates to the cable technology field, relates in particular to pressure drag combustion fire-resisting cable in a kind of aluminium alloy compact conductor.
Background technology
As everyone knows, common low pressure copper core fire-resisting cable production technology process is ripe, mostly be that wrapped mica has brought fire-resistant effect on the copper core conductor, but the cable of wrapped mica tape always can't pass through fire resistance test on aluminium core or aluminium alloy conductor, because the fusing point of aluminum or aluminum alloy is about 660 ℃, and the fire-resistant temperature of the B level of national Specification is 750～800 ℃, the fire-resistant temperature of A level is 950～1000 ℃, the aluminum or aluminum alloy conductor melts already then and can't use under these temperature, can only use the copper core conductor to make fire-resisting cable.Because the copper resource is fewer and feweri in recent years, the price of copper is more and more higher, and the proportion of copper is also big, is 3.29 times of aluminum or aluminum alloy, and the price of its copper core fire-resisting cable is also than expensive several times of aluminum or aluminum alloy cable.Because skyscraper was more and more in recent years, power consumption is increasing, low-voltage cable voltage drop in transmission course is increasing, and loss is also increasing, for fear of this situation, can adopt two kinds of approach: the cross section that the first, must increase cable, but it is limited that the cross section increases, greatly to a certain degree the time its cross-section of cable just can't manufacture, and the cross section is more big, its weight and laid down cost are just more big, also are to satisfy actual instructions for use.Another kind of approach is exactly: under the constant situation of through-put power, increase transmission voltage, reduce transmission current, reduce the voltage drop loss, during just need using, this presses fire-resistant aluminium core or aluminium alloy conductor cable, but aluminium conductor is because intensity is low, and surface easily oxidation produces the high resistant aluminum oxide film, causes contact resistance big easily, and percentage elongation is low, poor heat resistance, characteristics such as creep resisting ability is low, and overload capacity is little.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, provides a kind of transmission voltage height, fire resistance height, overload capacity is strong, thermal endurance is high, creep-resistant property is strong, corrosion resistance is high, pliability is high, percentage elongation is big, pressure drag combustion fire-resisting cable in the aluminium alloy compact conductor of in light weight, price and the characteristic that cost is low, fire resistance period is long.
The utility model is achieved through the following technical solutions:
Pressure drag combustion fire-resisting cable in a kind of aluminium alloy compact conductor, include the aluminium alloy compact conductor, the conductor compacting coefficient reaches about 0.93, be coated with screen, insulating barrier, shield dielectric layer and metal screen layer in the outside of conductor successively and constitute core, with the three stranded formation pair twist of core cable cores, be coated with lapping layer one, flame retardant coating, lapping layer two and restrictive coating successively in the described pair twist cable core outside, between pair twist cable core and lapping layer one, be provided with packed layer.
Described screen is semiconductive shielding layer, concentrates and the puncture cable to reduce the most advanced and sophisticated outstanding electric field that causes of conductive surface, and described insulation screen is the semiconductive insulation screen.
Described insulating barrier is crosslinked polyetylene insulated, to reduce the excessive generation flashover of insulating surface resistance.
Described metal screen layer is the wrapped shielding of copper strips.
Described packed layer is high flame retardant alkali-free glass fibre rope.
Described lapping layer is that high flame retardant alkali-free sized glass fibre band is wrapped, the adhesive curing of its surface-coated is one when high-temp combustion, play good flame and oxygen barrier effect, ceramic fire resistant layer behind the fixed combustion well, after the gluing glass fibre belt coats, can stand beaing and not embrittlement of standard code in the flame retardant coating combustion process.
The pottery silicon rubber flame retardant coating of described flame retardant coating for extruding, described restrictive coating is high flame retardant polyvinyl chloride oversheath material.
The utility model has the advantages that: the utility model flame retardant coating is in the cable core outside, not between conductor and insulation, flame can't burn on the conductor, and during burning, because the oxygen barrier heat-blocking action of flame retardant coating, heat can't be delivered to the cable core the inside from the outside, can't the melting aluminum alloy conductor, can adopt aluminium alloy conductor, because the relative copper conductor of aluminium alloy conductor, its proportion is little, and is in light weight, low price, raw material resources is abundant, and aluminium is the metallic element of content maximum in the earth's crust, adopts aluminium alloy conductor to make fire-resisting cable, can save a large amount of copper and fund, solve the phenomenon of China's copper resource scarcity.
