Description

The recent introduction of a double-twist strander with a 2500-mm reel for the manufacturing of 61-wire conductors with a large cross-section for medium voltage pushes the use of this alternative technology to limits that were in the past achievable only by conventional stranding machines. The rationale behind this is to obtain higher output, shorter loading time, and better overall efficiency, ultimately getting faster return on investment. This paper covers the technical aspects of the new equipment as well as a comparison of the several processes able to obtain medium-voltage conductors.
