Preferably, described coating adopts epoxy coating.
In the utility model, adopt rare earth aluminium alloy to make wire, ensured conductive capability, resistance to bend(ing), the corrosion resistance of cable, reduced weight, cost and the installation difficulty of cable simultaneously; One side metallo-plastic composite band is by wrapped conductor together time, and metal level plays the effect of screen, and the insulating barrier of plastic layer protection conductor reaches the effect of moisture-proof anticorrosive; Adopt epoxy coating, have advantages of high temperature resistant, bonding force is strong, the metal level of its protection single-layer metal plastics composite band is corrosion-resistant, single-layer metal plastics composite band and restrictive coating can also be bonded together, and further reaches the effect of combining closely; Low smoke and zero halogen cross-linked polyolefin sheath layer has protection and fire retardation, the gas low smoke and zero halogen of emitting when burning, environmental sound.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of low smoke and zero halogen rare earth aluminium alloy power cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of low smoke and zero halogen rare earth aluminium alloy power cable that the utility model proposes.
With reference to Fig. 1, a kind of low smoke and zero halogen rare earth aluminium alloy power cable the utility model proposes, comprises three conductors 1.
Conductor 1 is inner for adopting 8000 to be the wire 11 that rare earth aluminium alloy silk is made, when this rare-earth aluminum alloy lead wire 11 has ensured the conductive capability of cable, pliability is better than copper conductor, and weight is only 1/3rd of same volume copper conductor, use aluminium alloy conductor can alleviate cable weight, be convenient to install, and cost reduction.The outside coated crosslinked polyetylene insulated layer 12 of wire 11, insulating barrier 12 insulate conductor 1 each other.
By three parallel vertical cable cores that are set to of conductor 1; at the outside coated one side aluminium-plastic tape 2 of cable core; the plastic layer of this one side aluminium-plastic tape 2 is towards interior; be strapped in tightly together from outside by three conductors 1; the structure of all conductors 1 is carried out to stable processing, reached the effect of protection insulating barrier 2, moisture-proof anticorrosive simultaneously.And, the aluminum metal layer of one side aluminium-plastic tape 2 towards outside, play the effect of screen, reduce the impact of the suffered external electromagnetic waves of cable.In addition, one side aluminium-plastic tape 2 is soft flexible, does not affect the resistance to bend(ing) of cable.At the outside epoxy coating 3 that applies of aluminum metal layer of one side aluminium-plastic tape 2.That epoxy coating 3 has is high temperature resistant, anticorrosion, insulation, strong bonding property; it protects the aluminum metal layer of one side aluminium-plastic tape 2 corrosion-resistant on the one hand; on the other hand one side aluminium-plastic tape 2 and restrictive coating 4 are bonded together; reach the effect of combining closely; and it coordinates with the plastic layer of one side aluminium-plastic tape 2 corrosion resistance that has increased cable jointly, has extended the useful life of cable.At the outside coated low smoke and zero halogen cross-linked polyolefin sheath layer 4 of epoxy coating 3, it has protection and fire retardation, the gas low smoke and zero halogen of emitting when burning, environmental sound.
