Electrotechnical round copper wire

PURPOSE AND DESCRIPTION

Electrotechnical copper wire is used for manufacturing conductors, cables and cords and the most demanding types of products (enameled wire, LAN cable and etc)

Wire of MT (hard copper wire) and MM (soft copper wire) grades is produced in accordance with the requirements of TU 16-705.492-2005.

Nominal diameters are 1.15 - 4.50 mm.
