Home > Products > BARE CONDUCTOR > Galvanized steel wire (GSW)
Galvanized steel wire strand (GSW) is used for overhead ground lines or electrical power transmission lines.
Stay wire or guy wire strands are produced for use with poles, towers, or any other form of guying. And it usually is the inner core of ACSR.
