Bare copper, solid or concentrically stranded.  There are three varieties of copper: hard, moderately hard, and soft.

Also,we produce the this conductor according to standards BS7884, ASTM B8, NF C34-110, IEC 61089, DIN 48201-1 and so on.

Features

  1. Uniform and firm hot-dip zinc coating.
  2. Bright and clean surface.
  3. Excellent corrosion resistance.

Application

For overhead transmission and distribution applications, solid stranded bare copper. For uninsulated connections, jumpers, and grounding in electrical construction, the more elastic stranded conductors are appropriate.

Construction

Bare copper, solid or stranded. Available in tempers hard, medium-hard, or soft. In the hard and medium hard states, the multi-strand conductors are stranded concentrically, while in the soft tensioned state, combined single-strand stranding is used.

*The sizes of conductors which have been marked wih a single asterisk provide for one or more schedules of preferred series, and are commonly used in the industry. The sizes not marked are given simply as a matter of reference, and it is suggested that their use be discouraged.
1.To calculate the nominal diameters of Class C or Class D conductors or of any concentric-lay-stranded conductors made from round wires of uniform diameters, multiply the diamter of an individual wire (as given in Table 1) by that one of the following facors which applies:
2.Resistances (dc) apply to Class B. C. and D stranding. For other classes of stranding.refer to Test Method B193. Reistance (dc) based on annealed copper .
3.For conductors manfactured for subsequent coverning or insulating .
