Description
Technical field
This utility model relates to a kind of cable, is specifically related to a kind of aluminium alloy cable.
Background technology
Along with the development of science and technology, high-quality, the aluminium of high-tech content are developed, and the current resources situation of the most global lean copper richness aluminum, has been more than 3 times of aluminum valency before copper marked price, become again natural with " aluminum " for copper and select.
At present, aluminium alloy electric cable structure arranges unreasonable, and its conductor structure is all monolayer round conductor.And, existing aluminium alloy cable, its pliability and poorly conductive, use and have certain limitation.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of structure arranges rationally, and overall flexibility is good, conductor layering is pressed, and is effectively improved the layering aluminium alloy cable of the current capacity of cable.
Technical scheme: in order to solve above-mentioned technical problem, a kind of layering aluminium alloy cable described in the utility model, it includes aluminium alloy inner wire, point circular layers such as aluminium alloy it are provided with outside described aluminium alloy inner wire, it is provided with aluminium alloy domain layer outside point circular layers such as described aluminium alloy, described aluminium alloy etc. point circular layer is at least divided into two parts, it is provided with insulating barrier outside described aluminium alloy domain layer, it is provided with screen layer outside described insulating barrier, they form conductive unit, described insulating barrier and screen layer are co-extruded, described conductive unit is at least provided with two, it is provided with packed layer outside described conductive unit, it is provided with lapping layer outside described packed layer, cellosilk braid it is provided with outside described lapping layer, it is provided with alumina layer outside described cellosilk braid, it is provided with external sheath layer outside described alumina layer.
Described aluminium alloy etc. point circular layer is made up of eight parts.
Described insulating barrier is second the third insulating barrier.
Described packed layer is ethylene propylene diene rubber packed layer.
Described cellosilk braid by aramid fiber silk according to 1 repeatedly 1 vertical woven form.
Described external sheath layer is high-flame-retardanthalogen-free halogen-free low cigarette polyolefin sheath layer.
Beneficial effect: this utility model is compared with prior art, its remarkable advantage is: this utility model overall structure arranges rationally, Integral sealing, use layer-stepping conductor structure, the conductor structure that this layering is pressed can effectively reduce the CURRENT DISTRIBUTION inequality that conductor produces due to kelvin effect, the phenomenon that current capacity declines, improve effective usable floor area of cable body, thus improve the current capacity of cable, use insulating barrier and the screen layer of double-layer coextrusion, ensure that the insulating properties of cable, and prevent the generation of water tree, use the braid of aramid fiber silk composition and halogen-free and low-smoke flame-retardant polyolefin sheathed layer, it is effectively improved the flexibility of Integral cable, use alumina layer, flame can be stoped to occur or delay propagation of flame, this product operates steadily, safe and reliable, meet actual operation requirements.
