Chinese Manufacturer Customized Aerial Twisted Service Concentric Cable

Chinese Manufacturer Customized Aerial Twisted Service Concentric Cable

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,ASTM B 801, ASTM B800 .



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  aluminum 8000 serises , or 1350 Al, or Copper 
shall comply with the provisions of ASTM  standard . 

 

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 PVC. Must ensure the tightness of the set plus adequate resistance to ultraviolet rays (UV),Covering the entire concentric conductor will be placed a PVC coating.
