Description
Technical field
The utility model relates to field of cable technology, specifically belongs to a kind of fireproof wear-resisting aluminium alloy cable.
Background technology
Existing cable, generally adopts zinc-coated wire as core, the aluminium alloy wire of outer stranded circle.Mainly there is the problem of following several respects in this cable: one, due to skin stranded be circular aluminium alloy wire, cause gap between the lines large, net sectional area is little, and external diameter is large, stores and takes up room greatly in transportation.Two, uneven, rough by the stranded superficies formed of the aluminium alloy wire of circle, easily pile up ice and snow or other heavy burden materials, increase the heavy burden of cable, anti-ice-snow ability, easily bend and destroy cable.Three, the tensile strength of zinc-coated wire used is low, and during erection, span is less, and the shaft tower quantity of erection needed for cable is many, and not only cost is large, wasting manpower and material resources, and land occupation resource is many.Four, common aluminum alloy line allows normal working temperature to only have about 70 DEG C, and ampacity is very limited, and power transmission efficiency is low, and ampacity is little, and energy ezpenditure is large.
Utility model content
For the problems referred to above, the purpose of this utility model there is provided a kind of fireproof wear-resisting aluminium alloy cable, overcome the deficiencies in the prior art, reasonable in design, compact conformation, conductor by stranded formation conductor, improves tensile strength and the ampacity of conductor by be rectangle and cross section be in multiple cross section circular aluminum alloy conductor, between stranded aluminium alloy conductor, gap is little, and same volume same material improves ampacity.
The technical solution adopted in the utility model is as follows:
A kind of fireproof wear-resisting aluminium alloy cable, comprise conductor, described conductor is that rectangle cylinder aluminium alloy conductor is twisted into by a cylindrical aluminium alloy conductor and multiple cross section, described multiple cross sections are that the overall length of rectangle cylinder aluminium alloy conductor cross-sectional length equals cylindrical aluminium alloy conductor outside diameter, described conductor aluminium alloy conductor, flame retardant coating is surrounded by outside conductor, flame retardant coating is that two layers of two-sided mica tape overlap are wrapped, insulating barrier is surrounded by outside flame retardant coating, its insulating material adopted is LSOH anti-flaming cross-linked polyolefin, aramid fiber braided layer is woven with outside insulating barrier, organic silicon insulation layer of varnish is coated with outside aramid fiber braided layer.
Described conductor adopts 8176 and 8030 aluminium alloy conductors specified in ASTM B800-05.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model conductor is rectangle and a cross section by multiple cross section is that circular aluminum alloy conductor is by stranded formation conductor, improve tensile strength and the ampacity of conductor, between stranded aluminium alloy conductor, gap is little, same volume same material improves ampacity, make cable surface smooth simultaneously, improve anti-ice-snow function; Double-deck mica tape has good insulation property, hardness and water resistance, water-fast pouring and impact resistance; LSOH anti-flaming cross-linked polyolefin flameproof effect is good.Aluminium alloy conductor adopts the 8000 series alloys wires specified in ASTM B800-05 to substitute conventional copper product, so both can reduce costs, again can weight reduction, increase percentage elongation, compared with the copper conductor branch cable of replaceable specification, about gravity energy alleviates half.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See accompanying drawing, a kind of fireproof wear-resisting aluminium alloy cable, comprises conductor 1, and described conductor 1 is rectangle cylinder aluminium alloy conductor by a cylindrical aluminium alloy conductor 101 and multiple cross section
102 are twisted into, described multiple cross sections are that the overall length of rectangle cylinder aluminium alloy conductor cross-sectional length equals cylindrical aluminium alloy conductor outside diameter, described conductor aluminium alloy conductor, flame retardant coating 2 is surrounded by outside conductor 1, flame retardant coating 2 is that two layers of two-sided mica tape overlap are wrapped, insulating barrier 3 is surrounded by outside flame retardant coating 2, its insulating material adopted is LSOH anti-flaming cross-linked polyolefin, aramid fiber braided layer 4 is woven with outside insulating barrier 3, organic silicon insulation layer of varnish 5 is coated with outside aramid fiber braided layer 4, described conductor adopts 8176 and 8030 aluminium alloy conductors specified in ASTM B800-05, substitute conventional copper product, so both can reduce costs, again can weight reduction, increase percentage elongation, compared with the copper conductor branch cable of replaceable specification, about gravity energy alleviates half.By to be rectangle and cross section be in multiple cross section circular aluminum alloy conductor by stranded formation conductor, improve tensile strength and the ampacity of conductor, between stranded aluminium alloy conductor, gap is little, and same volume same material improves ampacity.
