Description
Technical field
This utility model relates to electric power cable technical field, particularly to a kind of fire-resistant aluminium alloy power cable of high temperature protection low pressure.
Background technology
Power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in Urban Underground electrical network, electric station lead line, industrial and mining establishment's in-line power and crosses power transmission line under the sea water of river.In power circuit, cable proportion is just gradually increased.Power cable is in order to transmit and to distribute the cable product of high-power power in the basic routing line of power system.Wherein low-voltage cable refers to be applicable to the fixing exchange 50Hz that is laid in, and rated voltage 6kv and following electric line is used as carry the power cable of electric energy.
Traditional power cable many employings copper conductor is as cable core material, but for reducing energy consumption, cost-effective, replacing copper conductor using aluminium alloy conductor has 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 less than Cu alloy material, so aluminium alloy cable high temperature resistance is not as copper core cable, it reduce its safety in utilization.
Utility model 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 fire-resistant aluminium alloy power cable of high temperature protection low pressure of applied range.
For solving the problems referred to above, this utility model offer techniques below scheme:
A kind of fire-resistant aluminium alloy power cable of high temperature protection low pressure; including cable core and sheath; some cable cores it are intervally distributed with in sheath; described cable core includes aluminium alloy conductive core material, fire-resistant isinglass belt lapping layer and insulating protective layer the most successively; between described sheath and each cable core, dense packing effect has flame resistant filler layer, is provided with temperature sense line in described sheath.
Wherein in an embodiment, described temperature sense line is arranged at center in sheath, and described cable core uniform intervals is distributed in edge of described temperature sense line week.
Wherein in an embodiment, described flame resistant filler layer is to be coincided by a plurality of fire retardant elastic adhesive tape in strip to compress the fire retardant elastic adhesive tape packed layer formed, and described fire retardant elastic adhesive tape is distributed along the bearing of trend of described aluminium alloy conductive core material.
Wherein in an embodiment, the described fire retardant elastic adhesive tape packed layer minimum spreading depth between cable core and sheath not less than cable core radius 1/4, and no more than cable core radius 1/2.
Wherein in an embodiment, described fire retardant elastic adhesive tape packed layer outer rim is surrounded with glass fibre lapping layer.
Wherein in an embodiment, in sheath, equidistantly it is laid with 4 cable cores.
Compared with prior art; this utility model is owing to being provided with temperature sense line; temperature detection protection can be carried out by described temperature sense line, when load temperature is higher than certain temperature, protection signal can be provided by temperature sense line or directly cut off the electricity supply to protect load equipment facility.

Fig. 1 is sectional structure schematic diagram of the present utility model.
Description of reference numerals: 1. aluminium alloy conductive core material, 2. fire-resistant isinglass belt wrapped, 3. insulating protective layer, 4. flame resistant filler layer, 5. glass fibre lapping layer, 6. sheath, 7, temperature sense line.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, detailed description of the invention of the present utility model is described in further detail:
With reference to a kind of fire-resistant aluminium alloy power cable of high temperature protection low pressure shown in Fig. 1; including cable core and sheath; some cable cores it are intervally distributed with in sheath; described cable core includes aluminium alloy conductive core material, fire-resistant isinglass belt lapping layer and insulating protective layer the most successively; between described sheath and each cable core, dense packing effect has flame resistant filler layer, is provided with temperature sense line in described sheath.
Owing to being provided with temperature sense line, temperature detection protection can be carried out by described temperature sense line, when load temperature is higher than certain temperature, protection signal can be provided by temperature sense line or directly cut off the electricity supply to protect load equipment facility.
Wherein in an embodiment, described temperature sense line is arranged at center in sheath, and described cable core uniform intervals is distributed in edge of described temperature sense line week.
Wherein in an embodiment, described flame resistant filler layer is to compress, for being coincided by a plurality of fire retardant elastic adhesive tape in strip, the fire retardant elastic adhesive tape packed layer formed, and described fire retardant elastic adhesive tape is distributed along the bearing of trend of described aluminium alloy conductive core material.I other words, a plurality of fire retardant elastic adhesive tape in strip is distributed along aluminium alloy conductive core material bearing of trend and is superimposed with each other, and forms described fire retardant elastic adhesive tape packed layer through mould extruding compression forming.Fire retardant elastic adhesive tape packed layer is coincided by a plurality of fire retardant elastic adhesive tape and is formed, can the most suitably increase and decrease fire retardant elastic adhesive tape bar number, stranded convenience, and owing to fire retardant elastic adhesive tape distribution arrangement is identical with aluminium alloy conductive core material bearing of trend, so further increasing overall tensile strength.Wherein, described fire retardant elastic adhesive tape, can be that fire-retardant TPE etc. is usually used in the insulating elastic material of cable-flame retardant and prepares.
Wherein in an embodiment, the described fire retardant elastic adhesive tape packed layer minimum spreading depth between two adjacent cable cores is not less than described insulation protection layer thickness.The fire retardant elastic adhesive tape being distributed between such two adjacent cable cores is provided that enough tensile strength, it is to avoid insulating protective layer is pulled or ruptures, and improves safety in utilization.
Wherein in an embodiment, the described fire retardant elastic adhesive tape packed layer minimum spreading depth between cable core and sheath not less than cable core radius 1/4, and no more than cable core radius 1/2.So under pulling force environment, the tension of cable is uniformly distributed, and further increases overall tensile strength.
Wherein in an embodiment, described fire retardant elastic adhesive tape packed layer outer rim is surrounded with glass fibre lapping layer.So that fire retardant elastic adhesive tape packed layer good integrity, roundness is high.Described glass fibre lapping layer can be that glass fiber tape is wrapped to be formed, and glass fiber tape fire resistance is good, further increases fire resistance.
Wherein in an embodiment, in sheath, equidistantly it is laid with 4 cable cores.
The above, it it is only preferred 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 example made according to technical spirit of the present utility model, all still fall within the range of the technical solution of the utility model.
