Concentric cable / Service Drop with aluminum or copper wire conductor/

 Low Price Best Quality Concentric Cable with AL Conductor

1,STANDARD

     The concentric conductors of copper and aluminum, is entirely consistent with the rules ASTM D 790, D 1248, D 2655, D 2656, UL 854, UL 44.

2,CHARACTERISTICS OF THE COPPER  AND ALUMINUM CONDUCTORS     

The concentric conductors of copper and aluminum, is entirely consistent with the rules ASTM D 790, D 1248, D 2655, D 2656, UL 854, UL 44, .

3,CONSTRUCTIVE CHARACTERISTICS

     Each material used in the conductor will be compatible with all other materials used in the manufacture of concentric conductor.

    Concentric conductor consists of one or two conductors which in turn are coated with a bare conductor distributed helically around the conductors.

    According to these configurations will have a phase and outer concentric neutral (bipolar), or two phases and these external neutral (tripolar)

    Section of all conductors that form the concentric conductor of both phases as the concentric neutral is the same.

4,Conductor:

    The materials used in the manufacture of concentric aluminum conductors formed by wires keychain aluminum 1350.

    Aluminum shall comply with the provisions of ASTM B 3 standard and UL 854.

    In the phase conductors with 7 wires, will be able to perform welding wires during wiring. Once this process is completed it will not be allowed two welds closer than 15m (50ft)

    According to paragraph 6 of ASTM B 8, the wiring process will be as follows:

Over the central conductor will be braided the rest of the layers. Braiding step will be at a distance to vary between 8 and 16 times the outside diameter. The lay direction of the  wires in the outer layer will be right.
