Product Description

8AWG/6AWG /4AWG copper/aluminum concentric cable electrical cables and wires

concentric cable for energy supply are used for industry and distribution boards, power stations, house connecting boxes and street lighting as well as control cable for the transmission of control impulses and test data. Overall, where increased electrical and also mechanical protection are required. Those cables are installed in open air, in underground, in water, indoors and in cable ducts. The concentric conductor (C) is allowed to use as PE-, PEN-conductor or as shield. due to the typical construction of concentric conductors it is possible to obtain many more cable joints, without cutting any conductor. In that way the operating reliability is guaranteed.

NORMS

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, numeral NEC 310.14, and the list provided in Annex 1 to this specification.

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.

Conductor:

The materials used in the manufacture of concentric copper conductors shall consist of soft copper wires class B and the composition of a pure copper will never lower than 99.85 and the concentric aluminum conductors formed by wires keychain aluminum alloy 8000 series (AA-8000).

Copper wires and aluminum shall comply with the provisions of ASTM B 3 standard and UL 854.

For bipolar concentric conductor, standard sections are # 8 and 10 AWG.

For tripolar concentric conductor, standard sections are # 8, 6, 4 y 2 AWG.

In the phase conductors with 7 wires, will be able to perform welding copper 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 copper wires in the outer layer will be right.

Isolation:

Each phase conductor will contain an insulating layer of XLPE for a temperature of 90 C. in the bipolar cables, over the insulating layer will be the braided neutral conductor helically with a passage between 8 and 16 times the outer diameter. In the tripolar cables over the isolation of each phase will have a PVC insulation filling in the joint of both cables and over this will be placed the neutral conductor.

Will be put over the concentric neutral conductor a tape and over this outer layer of XPLE. Must ensure the tightness of the set plus adequate resistance to ultraviolet rays (UV).

This last layer besides adding firmness should be smooth in appearance and will not be observed depressions caused by unfilled spaces beneath this layer.

Should not produce bubbles, cuts, tears or the presence of foreign materials that are detectable to the naked eye. Besides the envelope will be well centered.

The disposition of the tape around the bare conductor shall be performed as follows:

A single layer of tape with a convenient width helically applied without wrinkles or folds and with an overlap of at least 6mm. The tape will consist of nylon, with a thickness of at least 0.09mm.

Covering the entire concentric conductor will be placed a XLPE coating according the ASTM D 790, D 1248, D2655, and D2656 Standards.

The color of conductor insulation should be:

-Black: 2x #8, 2x #10

– When more than one phase will be distinguished by the black, blue and red colors.
