Aluminum 1350 PE Insulated Concentric Cable 2X8AWG

Aluminum 1350  PE Insulated Concentric Cable 2X8AWG

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

2.1 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 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.

Isolation:

 Each phase conductor will contain an insulating layer of PE 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 PVC. 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 PVC coating.

6)Welding Cable, Control Cable, Concentric Cable, Rubber Sheathed Cable and so on.

2.Which markets do you involve mainly in?
Our products have been exported mainly to Australia, Russia, Africa, Middle East, South-east Asia, South America,Central America,North America, Europe ,Austrapa, etc.

3. Which standards do you comply with when you produce the electrical wires and cables ?
We are able to produce electrical wires and cables based on GB, JB, IEC, BS, DIN, ASTM, JIS, NF, AS/NZS, CSA, etc. Meanwhile, we can design and manufacture the cables according to the samples and technical specification the customer provided.

4. What is the min.order quantity ?
It depends on the type and size of electrical wires and cables. For some small electrical wires, 100 meters can be accepted .But for the power cables with medium or high voltage, that should comply with the property of installed equipments. Anyhow,we will try our best to solve the problem and meet with the requirement If you have special request.

5. What is the production capacity per week or per month ?
For the bare conductor, we can finish 3000 tons within one month. For power cables, that depends on the type and size. The total output value per month is approx. USD3,000,000.00 for insulated aluminum cables and that is approx. USD8,000,000.00 for insulated copper cables.
