Description
Technical field
The utility model relates to electric power cable technical field, in particular to a kind of high temperature protection low-voltage aluminum alloy power cable.
Background technology
Power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in underground, city electrical network, power house lead line, industrial and mining enterprises are inner powers and transmission line under the seawater of mistake river. In electric power circuit, cable proportion increases just gradually. Power cable is in order to the cable product of transmission and distribution high-power power in the trunk circuit of power system. Wherein low-voltage cable refers to the power cable being applicable to be used as transmission of electric energy on fixing be laid in exchange 50Hz, voltage rating 6kv and following electric line.
Traditional power cable many employings copper conductor is as cable core material, but for reducing energy consumption, cost-saving, replacing copper conductor using aluminium alloy conductor has now become trend as cable core material. Compared to copper core cable, aluminium alloy cable good bending property. But owing to aluminum alloy materials high temperature resistant property is lower than Cu alloy material, so aluminium alloy cable high-temperature resistance is not as copper core cable, it reduce its safety in utilization.
Practical novel content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of safety in utilization is good, the high temperature protection low-voltage aluminum alloy power cable of applied range.
For solving the problem, the utility model provides following technical scheme:
A kind of high temperature protection low-voltage aluminum alloy power cable; comprise cable core and sheath; some cable cores it are intervally distributed with in sheath; described cable core comprises aluminium alloy conductive core material and wrapped in the insulating protective layer of aluminium alloy conductive core material; between described sheath and each cable core, dense packing effect has packing layer, is provided with temperature induction line in described sheath.
Wherein in an embodiment, described temperature induction line is arranged in sheath center, and described cable core is evenly spaced apart in described temperature induction line week edge.
Wherein in an embodiment, described packing layer is that described elastic adhesive tape distributes along the bearing of trend of described aluminium alloy conductive core material by many elastic adhesive tape elastic adhesive tape packing layers that repeatedly combined pressure contracts and formed in strip.
Wherein in an embodiment, the minimum spreading depth of described elastic adhesive tape packing layer between cable core and sheath is not less than the 1/4 of cable core radius, and is not more than the 1/2 of cable core radius.
Wherein in an embodiment, described elastic adhesive tape packing layer outer rim is surrounded with non-woven fabrics lapping layer.
Wherein in an embodiment, the spacing such as sheath is interior are laid with 4 cable cores.
Compared with prior art; the utility model is owing to being provided with temperature induction line; undertaken by described temperature induction line visiting temperature protection, when load temperature is higher than certain temperature, provides protection signal by temperature induction line or directly cut off the electricity supply to protect load installations and facilities.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present utility model.
Description of reference numerals: 1. aluminium alloy conductive core material, 2. insulating protective layer, 3. packing layer, 4. non-woven fabrics lapping layer, 5. sheath, 6. temperature induction line.
Embodiment
Below in conjunction with Figure of description and embodiment, embodiment of the present utility model is described in further detail:
With reference to a kind of high temperature protection low-voltage aluminum alloy power cable shown in Fig. 1; comprise cable core and sheath; some cable cores it are intervally distributed with in sheath; described cable core comprises aluminium alloy conductive core material and wrapped in the insulating protective layer of aluminium alloy conductive core material; between described sheath and each cable core, dense packing effect has packing layer, is provided with temperature induction line in described sheath.
Owing to being provided with temperature induction line, undertaken by described temperature induction line visiting temperature protection, when load temperature is higher than certain temperature, provides protection signal by temperature induction line or directly cut off the electricity supply to protect load installations and facilities.
Wherein in an embodiment, described temperature induction line is arranged in sheath center, and described cable core is evenly spaced apart in described temperature induction line week edge.
Wherein in an embodiment, described packing layer is that described elastic adhesive tape distributes along the bearing of trend of described aluminium alloy conductive core material by many elastic adhesive tape elastic adhesive tape packing layers that repeatedly combined pressure contracts and formed in strip. That is to say, many elastic adhesive tapes in strip distributes along aluminium alloy conductive core material bearing of trend and are superimposed with each other, and form described elastic adhesive tape packing layer through mould extruding compressed moulding. Elastic adhesive tape packing layer is repeatedly closed by many elastic adhesive tapes and is formed, and can suitably increase and decrease elastic adhesive tape number, stranded convenience as required, and due to elastic adhesive tape distribution arrangement identical with aluminium alloy conductive core material bearing of trend, so further increasing overall tensile strength.
Wherein in an embodiment, the minimum spreading depth of described elastic adhesive tape packing layer between two adjacent cable cores is not less than described insulating protective layer thickness. The elastic adhesive tape distributed between two adjacent cable cores like this can provide enough tensile strength, avoid insulating protective layer pull or rupture, it is to increase safety in utilization.
Wherein in an embodiment, the minimum spreading depth of described elastic adhesive tape packing layer between cable core and sheath is not less than the 1/4 of cable core radius, and is not more than the 1/2 of cable core radius. So under pulling force environment, the tensile stress of cable is uniformly distributed, and further increases overall tensile strength.
Wherein in an embodiment, described elastic adhesive tape packing layer outer rim is surrounded with non-woven fabrics lapping layer. So that elastic adhesive tape packing layer good integrity, roundness height.
Wherein in an embodiment, the spacing such as sheath is interior are laid with 4 cable cores.
The above, it it is only better embodiment of the present utility model, not technical scope of the present utility model is made any restriction, therefore every any trickle amendment, equivalent variations and modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of the technical solution of the utility model.
