Description
Technical field
The utility model relates to cable, particularly relates to a kind of colliery low smoke and zero halogen scandium-aluminum alloy conductor mobile monitoring type flexible cable.
Background technology
Coal is a kind of mineral resources at occurring in nature, and current China coal mining industry enters Electrification Age comprehensively, and coal mine cable use amount is very large, and the conductor main component manufacturing cable is copper, accounts for about 70% of total copper consumption.But China's copper resource is very short, along with the exhaustion of COPPER IN CHINA resource, COPPER IN CHINA 80% needs import, and dependence is large.Along with constantly riseing of copper valency, copper is replaced to be the inexorable trend that electric wire develops with aluminium.The electric wire more than 80% of France is aluminium conductor, and the aluminum conductor of Japan also accounts for more than 50%.China's bauxite resource is very abundant, but application quantity is less than 1%, main or because aluminum conductor manufacturing technology immature caused by, therefore obtaining technical breakthrough is the key addressed this problem.
Past fine aluminium is used as electric wire and cable conductor and exists a lot of not enough, being rarely used in insulated wire cores, for being drawn into thinner wire rod, being used as wiring, electromagnetic wire and telecommunication cable, especially difficulty.Because the intensity of aluminium and elongation can not meet requirement, so aluminium alloy is all be used as aerial condutor substantially both at home and abroad, be rarely used in and prepare cable insulation core, sometimes discharging a large amount of smog and toxic gas absence from work without reason when colliery runs into fire cable fire can be therefore poisoning dead, also do not have up to now a kind of have excellent electric conductivity, cheap electric conducting material and burning time discharge the smog of trace, discharge as Coal Electricity cable without toxic gas.
Utility model content
For solving above-mentioned technological deficiency, the utility model object is to provide a kind of colliery low smoke and zero halogen scandium-aluminum alloy conductor mobile monitoring type flexible cable.
Scheme of the present utility model is as follows: a kind of colliery low smoke and zero halogen scandium-aluminum alloy conductor mobile monitoring type flexible cable, comprises oversheath, power wire core and inner sheath; Described power wire core is extruded in successively on scandium-aluminum alloy conductor by insulation screen, insulating barrier and conductor shield to form; Described inner sheath is add weaving metallic fibers in the low smoke and zero halogen rubber of base-material to form by ethylene-propylene diene copolymer, after three power wire core are stranded, cable core is overmolding to by inner sheath, set gradually semi-conductive tape covering, type insulating wrapping strip and oversheath outside described cable core, be distributed with three along cable circumferencial direction decile in described semi-conductive tape covering and monitor core.
Described scandium-aluminum alloy conductor adopts the thin tinned wird of multiply stock strand and the structure that tangles again in the same way outward.
Described insulating barrier and oversheath all adopt ethylene-propylene diene copolymer to be the low smoke and zero halogen rubber insulation layer of base-material.
The beneficial effects of the utility model: the utility model structural design is simple, and softness is good, cable conductor core not easy fracture, there is creep resistant, high pliable and tough, strong extension, low bounce-back, feature that connective stability is good, conduct electricity very well, without toxic gas release, can greatly reduce costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Wherein: 1, scandium-aluminum alloy conductor; 2, conductor shield; 3, insulating barrier; 4, insulation screen; 5, inner sheath; 6, core is monitored; 7, type insulating wrapping strip; 8, oversheath; 9, semi-conductive tape covering.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, a kind of colliery low smoke and zero halogen scandium-aluminum alloy conductor mobile monitoring type flexible cable, comprises oversheath, power wire core and inner sheath; Described power wire core is extruded in successively on scandium-aluminum alloy conductor 1 by insulation screen 4, insulating barrier 3 and conductor shield 2 to form; Described inner sheath 5 is add weaving metallic fibers in the low smoke and zero halogen rubber of base-material to form by ethylene-propylene diene copolymer, after three power wire core are stranded, cable core is overmolding to by inner sheath 5, set gradually semi-conductive tape covering 9, type insulating wrapping strip 7 and oversheath 8 outside described cable core, be distributed with three along cable circumferencial direction decile in described semi-conductive tape covering 9 and monitor core 6.Adopt scandium-aluminum alloy conductor 1, its intensity 211MPa after tested, conductance 62.0%IACS, elongation 31.8%, yield strength 110MPa, the fine aluminium of solving over is used as a lot of deficiency of electric wire and cable conductor existence on the one hand, has the advantage such as creep resistant, high pliable and tough, strong extension, low bounce-back, stable connection.This cable also reduces the cost 50% of cable on the other hand, discharges the smog of trace simultaneously, discharge without toxic gas during burning.Be mainly used in the connection of underground coal mine phase shifting transformer and similar devices, cable can move freely with equipment, and the electric conductivity of cable is greatly improved.
Described scandium-aluminum alloy conductor 1 is outer adopts the thin tinned wird of multiply stock strand and the structure that tangles again in the same way, the pitch of stock strand and multiple strand will control in certain scope, and for stock strand and multiple strand strand are to identical, can allow cable bending and dilatory time, due to the flexibility of cable and ductility good, the stressed very little power wire core conductor that also efficiently avoid of conductor is pulled off with curved disconnected.
Described insulating barrier 3 and oversheath 8 all adopt ethylene-propylene diene copolymer to be the low smoke and zero halogen rubber insulation layer of base-material, have the effect of fire-retardant, oil resistant, high temperature resistant, wear-resisting, waterproof, can greatly reduce the harm to human body.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection range of the present utility model.
