Abstract
The utility model discloses a flame-retardant armored copper-clad aluminum power line for a communication power supply, which comprises a core composed of three copper conductors. Each copper conductor is formed by twisting a plurality of copper-clad aluminum wires. A casting polypropylene belt is wound and wrapped on the outer surface of each copper conductor. An insulating environment-friendly flame-retardant first polyvinyl chloride layer is wrapped on the outer surface of each casting polypropylene belt. A polyvinyl chloride belt is wound and wrapped on the outer surface of the core. Fillers are filled inside the gap between the core and the polyvinyl chloride belt. An armored layer formed by making two layers of zinc-coating steel bands wound and wrapped in a spaced way is wrapped on the outer surface of the polyvinyl chloride belt. An environment-friendly flame-retardant second polyvinyl chloride layer serving as a sheath is wrapped on the outer surface of the armored layer. The flame-retardant armored copper-clad aluminum power line for the communication power supply has the advantages of lightness, low cost and stable prices, etc. The defects that the copper cost is high and the copper price is fluctuating drastically, etc. are further overcome.

The utility model purpose provides a kind of communication power supply with fire-retardant armouring copper cover aluminum power line, and in light weight, advantages such as cost is low, price steadiness that this power line has have overcome drawbacks such as copper cost height, price big rise and big fall.
For achieving the above object, the technical solution adopted in the utility model is: a kind of communication power supply is with fire-retardant armouring copper cover aluminum power line, comprise the core of being formed by three copper conductors, described copper conductor is closed by some copper cover aluminum skein silks and forms, one curtain coating polypropylene tape is wrapped in described copper conductor outer surface, one first polyvinyl chloride layer as the environmental protection flame retardant that insulate is coated on described cast polypropylene band outer surface, one polyvinyl chloride band is wrapped in described core outer surface, be filled with filler in the gap between described core and the polyvinyl chloride band, one is coated on described polyvinyl chloride band outer surface by the wrapped armour that forms in two-layer galvanized steel strip gap, and second polyvinyl chloride layer as the environmental protection flame retardant of sheath is coated on described armour outer surface.
It is as follows further to improve technical scheme in the technique scheme:
1, in the such scheme, the diameter of described copper-clad aluminium wire is 0.40mm.
2, in the such scheme, the thickness of described polyvinyl chloride band is 0.4mm.
3, in the such scheme, the galvanized steel strip thickness in the described armour is 0.2mm, and the clearance rate of this armour is at least 50%.
Because technique scheme is used, the utility model compared with prior art has following advantage and effect:
The utility model communication power supply has in light weight, advantages such as cost is low, price steadiness with fire-retardant armouring copper cover aluminum power line, has overcome drawbacks such as copper cost height, price big rise and big fall; Secondly, saved a large amount of rare copper resources, alleviated cable weight and labor strength, be convenient to transportation and construction, and clad welded method production technology has been also free from environmental pollution; Secondly, the galvanized steel strip thickness in the described armour is 0.2mm, and the clearance rate of this armour is at least 50%, has further improved the power line electrical property.
