Abstract
The utility model discloses a reinforced-type fireproof and waterproof aluminium alloy power cable, comprising a plurality of aluminium alloy conductors, and inorganic insulating layers, wherein the inorganic insulating layers are wrapped at the outer sides of the plurality of aluminium alloy conductors respectively, tensile cores are arranged in the plurality of aluminium alloy conductors respectively, the plurality of aluminium alloy conductors wrapped with the inorganic insulating layers are mutually twisted into a bundle to form a cable core, an inner fireproof layer is wrapped outside the cable core, a filling layer is arranged between the inner fireproof layer and the cable core, an inner waterproof layer formed by lapping waterproof tapes in an overlapping manner is arranged outside the inner fireproof layer, an outer fireproof layer is wrapped outside the inner fireproof layer, an outer waterproof layer is wrapped outside the outer fireproof layer, an armour layer and a sheath layer are sequentially wrapped outside the outer waterproof layer, and tensile steel wires are uniformly distributed in the sheath layer. The reinforced-type fireproof and waterproof aluminium alloy power cable disclosed by the utility model is especially suitable for the occasions having a rated voltage of 3 kV and lower and high fireproof and waterproof requirements; aluminium alloy is adopted as the conductors of the cable, thus effectively decreasing the cost of the cable; additionally, the mechanical strength of the cable is improved, thus prolonging the service life of the cable.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of reinforced fire-proof and water-proof aluminium alloy electric power cable.
Background technology:
Along with international copper valency one tunnel is high, China many wires and cables industries manufacturer suffers untold misery.A few days ago, the Senior Expert of China's non-ferrous metal industry representes that the aluminium of electric wire is a kind of development trend for copper, has got long long way to go but will reach desirable effect.
According to expert introduction, this high-low temperature resistant aluminium alloy cable security performance is superior to the copper core cable, when its surface contacts with air, with forming a kind of thin and firm oxide layer, can tolerate various corrosion.Produce high-strength croop property because added iron,, also can guarantee to connect stable even at long term overloading with when overheated.
In addition, the ballistic properties of this aluminium alloy cable is littler by 40% than copper cable, and flexility is higher by 24% than copper cable, because the weight of high-and low-temperature resistance aluminium alloy cable is merely 50% of copper cable, also can effectively reduce installation cost.
How improving fireproofing of cable fire resistance characteristic and mechanical strength is problem demanding prompt solution,
The utility model content:
The purpose of the utility model provides a kind of reinforced fire-proof and water-proof aluminium alloy electric power cable, has the excellent waterproof fire protecting performance, and it is good and excellent mechanical performance, security performance, switching performance arranged to have economic performance again.
The technical scheme of the utility model is following:
Reinforced fire-proof and water-proof aluminium alloy electric power cable; It is characterized in that: comprise several aluminium alloy conductors, inorganic insulation layer, described several aluminium alloy conductors outside is enclosed with inorganic insulation layer respectively, is respectively equipped with tensile core in described several aluminium alloy conductors; The mutual stranded bunchy of several aluminium alloy conductors of described parcel inorganic insulation layer constitutes cable core; Cable core is wrapped with the interior fireprotection layer of the overlapping wrapped formation of double-deck fire-resistant isinglass belt, is provided with the packed layer that the refractory glass fibre silk constitutes between interior fireprotection layer and the cable core, and interior fireprotection layer is provided with the inner waterproofing layer of the overlapping wrapped formation of water blocking tape outward; The inner waterproofing layer is wrapped with the outer fireprotection layer of the overlapping wrapped formation of double-deck high temperature resistance polyester film band; Outer fireprotection layer is wrapped with exterior waterproof coating, and exterior waterproof coating is enclosed with armour, restrictive coating outward successively, is evenly distributed with the tension steel wire in the restrictive coating.
Described reinforced fire-proof and water-proof aluminium alloy electric power cable is characterized in that: described armour adopts the tin plated steel wire braiding to form.
The utility model has the advantages that:
The utility model particularly suitable rated voltage 3kV and the demanding occasion of following fire-proof and water-proof adopt the conductor of aluminium alloy as cable, have reduced the cost of cable effectively, and the mechanical strength of this outer cable promotes, and has prolonged the useful life of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Reinforced fire-proof and water-proof aluminium alloy electric power cable; Comprise several aluminium alloy conductor 1, inorganic insulation layer 2, several aluminium alloy conductors 1 outside is enclosed with inorganic insulation layer 2 respectively, is respectively equipped with tensile core 3 in several aluminium alloy conductors 1; Several aluminium alloy conductors 1 mutual stranded bunchy of parcel inorganic insulation layer 2 constitutes cable core; Cable core is wrapped with the interior fireprotection layer 4 of the overlapping wrapped formation of double-deck fire-resistant isinglass belt, is provided with the packed layer 5 that the refractory glass fibre silk constitutes between interior fireprotection layer 4 and the cable core, the interior fireprotection layer 4 outer inner waterproofing layers 6 that are provided with the overlapping wrapped formation of water blocking tape; Inner waterproofing layer 6 is wrapped with the outer fireprotection layer 7 of the overlapping wrapped formation of double-deck high temperature resistance polyester film band; Outer fireprotection layer 7 is wrapped with exterior waterproof coating 8, is enclosed with armour 9, restrictive coating 10 successively outside the exterior waterproof coating 8, is evenly distributed with tension steel wire 11 in the restrictive coating 10.
Armour 9 adopts the tin plated steel wire braiding to form.
