Description
Technical field
The utility model relates to a kind of power cable, particularly high winding degree rare earth alloy cable.
Background technology
Traditional aluminum alloy cable conductor is round for pressing, and activity coefficient is less than 0.90, and the gap in conductor between monofilament and monofilament is very large, and cable easily makes moist and intakes, and causes cable to be energized; And due to cable flexibility poor, the bad back bending in turning when mounted, the bending radius after installation is large; Common steel-tape armouring can produce eddy current loss and circulation loss, makes electric cable heating, reduces the useful life of ampacity and insulation; Cable is when repeatedly moving, and easy scratch insulation, need use crane span structure when building is installed; The bending radius of cable is made troubles to installation and takies very large installing space greatly; And the fire resistance of cable is also poor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high winding degree rare earth alloy cable, and this cable flexibility is good, wear-resistant, saves installing space, does not produce eddy current loss and circulation loss, thus overcome above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of high winding degree rare earth alloy cable, it is made up of conductor, insulated wire cores, packed layer, wrapped belt, metallic jacket or metal armor layers, external sheath layer from inside to outside, conductor is molded line lay configuration, and conductor forms by many trapezoidal rare earth aluminium alloy monofilament are stranded; Insulated wire cores extrudes the coloured Insulation Material of one deck by conductive surface and is formed, and packed layer is be filled in the flame resistant glass gasket for packing in insulated wire cores stranding post gap, and wrapped belt is wrapped refractory ceramic twining package tape outside insulated wire cores; Metallic jacket or metal armor layers are the wrapped aluminum alloy strip on wrapped belt surface or stainless steel band, and the profile of metallic jacket or metal armor layers is wrinkle shape, and metallic jacket or metal armor layers curl up the surface at wrapped belt in the shape of a spiral; External sheath layer is one deck flame-proof polyvinyl chloride sheath or the low smoke, zero halogen polyolefin jacket that are extruded in metallic jacket or metal armor layers surface.
In above-mentioned high winding degree rare earth alloy cable, the activity coefficient of conductor is not less than 0.93.
In aforesaid high winding degree rare earth alloy cable, insulated wire cores quantity is 3 ~ 5 cores; Coloured Insulation Material is organosilane crosslinked polyethylene insulation material or LSOH anti-flaming polyolefin Insulation Material.
Beneficial effect: compared with prior art, conductor of the present utility model is molded line lay configuration, conductor forms by many trapezoidal rare earth aluminium alloy monofilament are stranded, and the activity coefficient of conductor is not less than 0.93, compared to traditional circular monofilaments conductor, its conductor gap is little, closely stranded, longitudinal water-blocking effect can be played, conduct electricity very well, simultaneously shared reduced space, reduce cable size, bring convenience to installation.Aluminium alloy conductor adopts full annealing mode, improve the suppleness of conductor, reduce the bending radius after cable installation, solve because the bending radius of cable is greatly to installing the problem making troubles and take very large installing space, DC resistance simultaneously during cable conductor 20 DEG C declines 5 ~ 8%, improves the ampacity of cable.The utility model adopts the chain armouring mode of aluminum alloy strip, cable run time can not with aluminum alloy strip magnetic field, the profile of metallic jacket of the present utility model or metal armor layers is wrinkle shape, material is aluminium alloy, curl up the surface at wrapped belt in the shape of a spiral, serve the object of reaming, better softness, bending radius is little, its material itself does not produce eddy current loss, circulation loss, improve ampacity and insulate useful life, solve the problem that common steel-tape armouring can produce eddy current loss and circulation loss, because chain armouring mode is soft, also improve the flexibility of cable.Because aluminium alloy cable is lightweight, pliability is good, is convenient to mounting and installation, so can save cable testing bridge, packed layer of the present utility model, wrapped belt and external sheath layer all adopt flame-retarding characteristic material, and when can ensure that cable burns in energising situation, cable conductor can not be blown.Insulated wire cores of the present utility model adopts different colours, is used for distinguishing the difference of each core.External sheath layer is one deck flame-proof polyvinyl chloride sheath or the low smoke, zero halogen polyolefin jacket that are extruded in metallic jacket or metal armor layers surface, and resisting deflection is strong, is not easily scraped off in repeatedly moving.
