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.

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.

DIMENSIONAL CHARACTERISTICS.

The dimensional characteristics of copper and aluminum conductors conformed to the provisions of paragraph 7 of 8 ASTM standard, whose main characteristics are given in the following.
