Abstract
An aluminum alloy cable with creep-resistant and high resistance water characteristics is disclosed. The aluminum alloy conductor is formed by three fan-shaped aluminum alloy filaments and a plurality of trapezoidal aluminum alloy filaments through circular pressing. A center of the aluminum alloy conductor is three 120 degree fan-shaped filaments and other aluminum alloy filaments are trapezoidal filaments. A resistance water yarn is longitudinally arranged between the each layer of aluminum alloy filaments. A layer of high pure XLPE is extruded on the conductor so as to be taken as an insulating layer. During cabling of an insulation core, a resistance water rope filling material is added and a resistance water tape is wrapped in an overlap state. An aluminum-plastic composite resistance water layer is arranged outside the resistance water tape. Finally, a layer of low-smoke halogen-free flame-retardant irradiation crosslinking polyolefin or other termite-proof and rat-proof sheath material is extruded so as to be taken as an outer protection layer.
Description
Technical field
The utility model is a kind of water repellent electric cable, particularly a kind of creep resistant, high water resistant aluminium alloy cable.
Background technology
At present, the Some Domestic electric wire manufacturing enterprise aluminium alloy power cable that taken the lead in developing is all obtained major technological breakthrough on security performance, electric property, mechanical performance, satisfy national current standard requirement fully.When the cross-sectional area of conductor of aluminium alloy cable is long-pending when being 1.5 times of copper core, both can reach suitable electric property, in the suitable situation of electric property, the advantage of aluminium alloy cable itself will be more obvious: low cost, directly purchase cost is than the low 30%-40% of copper cable, common buildings is saved the installation expense more than 20%, and long span building can be saved more than 40%; Lightweight, only be half of equal copper cable, easily transportation, easily lay etc.For big-and-middle-sized engineering, comprehensive saving of aluminium alloy cable energy realization fund, human and material resources.The aluminium alloy cable of multi-size when promoting domestic cable core competitiveness, also will be made huge contribution to Society in abundant existing cable products kind.
Yet, at naval vessels, boats and ships, under water, the extraordinary occasion cabling such as tunnel, subway, underground piping, just necessarily require electric wire not only to have radially water resistance, but also to have good longitudinal water-blocking performance, this is the not available performance of aluminium alloy aluminium cable that provides in the market.So it is extremely urgent to solve aluminium alloy cable high water resistant performance.
The utility model content
The purpose of this utility model provides the aluminium alloy cable of a kind of creep resistant, high water resistant performance.The utility model is realized by following technical proposals:
The aluminium alloy cable of a kind of creep resistant, high water resistant performance, its aluminium alloy conductor are to be pressed by three fan-shaped aluminium alloy monofilament and the trapezoidal aluminium alloy monofilament of Duo Gen circle to form.Described aluminium alloy conductor center is three 120 ° of fan-shaped monofilament, and all the other each layer aluminium alloy monofilament are trapezoidal monofilament.Press coefficient more than 0.96 between described each layer aluminium alloy monofilament, between the every layer of described aluminium alloy monofilament that presses the strand system, put water blocking yarn, so that the aluminium alloy conductor that presses is more fine and close, intercepted vertically entering of hydrone.
Described aluminium alloy conductor pushes the high pure XLPE material of one deck outward as insulating barrier, forms insulated wire cores; Three of described insulated wire cores are twisted into cable core, cable core gap-fill waterproofing rope inserts, the outer overlapping wrapped one deck waterstop of cable core, waterstop arranges plastic-aluminum combined water blocking layer outward, and the aluminium foil that plastic-aluminum combined water blocking layer is 0.05mm～0.10mm by vertical bag thickness is that 0.5mm～1.0mm high density polyethylene (HDPE) consists of with extruding thickness; Plastic-aluminum combined water blocking layer arranges outer jacket outward, and outer jacket is comprised of the low-smoke non-halogen flame-retardant cross-linking radiation polyolefin that extrudes, and also replaceable according to use occasion is termite-proof, protection against rodents protective cover material.
The beneficial effects of the utility model are: conductor adopts aluminum alloy materials, and aluminium alloy replaces smart copper as conductor, greatly reduces production costs when having guaranteed electrical property, and aluminium alloy is high temperature resistant and be not easy oxidation, and corrosion resistance is better; The monofilament that forms aluminium alloy conductor is molded line, and specific geometry makes the stranded gap of conductor minimum, presses coefficient and reaches more than 0.96, has effectively stoped vertically entering of hydrone; The vertical water blocking yarn of putting of every layer of conductor filled residual gap, make between the aluminium alloy conductor monofilament that presses, layer by layer between compact and firm, more efficiently stoped hydrone vertically, radially enter.Add waterproofing rope during stranding as inserts and wrapped waterstop, all improved block-water performance; Plastic-aluminum combined water blocking layer is set, so that the radial water-resisting performance of cable is more remarkable in the outer jacket; Through the low smoke halogen-free flame-retardant polyolefin of cross-linking radiation, mechanical performance is excellent, and during cable fire, and nontoxic, low cigarette, fire-retardant can also play the effects such as termite-proof, protection against rodents.This utility model belongs to environment-friendly products.Can not pollute surrounding environment, and safe.
