*ACS wire: Aluminum clad steel wire
Medium distance overhead line, suitable for transmission of high current carrying capacity. Small size low loss thermal conductor meets peak-capacity requirement, applied instead of large-size ACSR. This reduces comprehensive investment costs by 15%-20% annually, considering conductor, fittings, tower and transmission loss.
