Description

A kind of coaxial rare earth aluminium alloy cable
Technical field:
This utility model relates to coaxial cable, particularly relates to a kind of coaxial rare earth aluminium alloy cable.
Background technology:
The ballistic properties of rare earth aluminium alloy cable is lower by 40% than copper cable, flexility is higher by 30% than copper cable, because the weight of rare earth aluminium alloy cable is only the 50% of copper cable, cable minimum bending radius is 7 times of outside diameters of cable, and copper cable is 12 ~ 15 times, can effectively reduce installation integrated cost.Same cable current-carrying capacity situation, rare earth aluminium alloy cable is cost-effective than copper core cable reaches more than 40%.
Therefore, the application of rare earth aluminium alloy cable in the market is more and more extensive, and in coal mining enterprise, the co-axial connecting cable of underground moving transformer station does not the most use rare earth aluminum alloy conductor.
Utility model content:
The purpose of this utility model is to provide a kind of coaxial rare earth aluminium alloy cable, and in frequent moving process, cable core intensity and pliability are good, and therefore, economical energy is excellent and has the security performance of excellence, fire resistance.
The technical solution of the utility model is as follows:
Coaxial rare earth aluminium alloy cable, it is characterized in that: include central inner conductor, coating ceramic fibrage warp resistance layer successively outside central inner conductor, polyether-ether-ketone insulating barrier constitutes interior insulated wire cores, interior insulated wire cores extrusion moulding is in low smoke halogen-free flame-retardant polyolefin-150 carrier layer, low smoke halogen-free flame-retardant polyolefin-150 carrier layer outside interior insulated wire cores has the separate chamber of several ellipses along annular spread, external insulation core it is provided with in separate chamber, ceramic fibre silk and the high temperature resistant clad of pyroceram silk composition it is filled with between external insulation core and separate chamber, it is coated with successively outside low smoke halogen-free flame-retardant polyolefin-150 carrier layer and adds the third polyolefin waterproof layer coagulating water-proof emulsion, Magnesium-aluminum alloy wire braid, polyether-ether-ketone external sheath layer.
Described coaxial rare earth aluminium alloy cable, it is characterised in that: described central inner conductor, the conductor of external insulation core all use rare earth aluminium alloy line to constitute according to number of share of stock bunchy more stranded than 2:1 with aramid fiber yarn.
The utility model has the advantages that:
This utility model novel in structural design, internal and external conductor uses rare earth aluminium alloy line and the compound composition of aramid fiber yarn, coordinate the rational structure of outer wall, ensure that cable core intensity and pliability are good in frequent moving process, external insulation core is individually at resistant to elevated temperatures chamber indoor distribution, and resistance to elevated temperatures is remarkable, in addition, cable also has with low cost, service life length advantage.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
See accompanying drawing:
Coaxial rare earth aluminium alloy cable, including central inner conductor 1, the outer coating ceramic fibrage warp resistance layer 2 successively of central inner conductor 1, polyether-ether-ketone insulating barrier 3 constitutes interior insulated wire cores, interior insulated wire cores extrusion moulding is in low smoke halogen-free flame-retardant polyolefin-150 carrier layer 4, low smoke halogen-free flame-retardant polyolefin-150 carrier layer 4 outside interior insulated wire cores has the separate chamber 5 of several ellipses along annular spread, external insulation core 6 it is provided with in separate chamber 5, ceramic fibre silk and the high temperature resistant clad 7 of pyroceram silk composition it is filled with between external insulation core 6 and separate chamber 5, outer being coated with successively of low smoke halogen-free flame-retardant polyolefin-150 carrier layer 4 adds the third polyolefin waterproof layer 8 coagulating water-proof emulsion, Magnesium-aluminum alloy wire braid 9, polyether-ether-ketone external sheath layer 10.
Central inner conductor 1, the conductor of external insulation core 6 all use rare earth aluminium alloy line to constitute according to number of share of stock bunchy more stranded than 2:1 with aramid fiber yarn.
