Construction & selection
Bare stranded hard-drawn copper conductor family for overhead applications. The illustration represents bare copper construction; conductor size and mechanical performance require selection from the current datasheet.
For technical data and a quotation, use Contact in the main navigation and include this cable family in your enquiry.
Construction
Illustrated variant: HDBC bare copper
- Hard-drawn copper strands
Hard-drawn copper strands make up the bare current-carrying conductor.
- Bare stranded conductor assembly
The strands are laid together as a bare conductor, without insulation or an outer sheath.
Construction source: supplier overhead conductor reference catalogue, page 8.
