Tw Galvanized Steel Wire Overhead Transmission Line Bare.
Product Description
Tw Galvanized Steel Wire Overhead Transmission Line Bare.
Overhead conductor,Bare conductor AAAC conductor used as overhead conductor referred to have higher strength but lower conductivity than pure aluminum.being lighter, alloy conductors can sometimes be used to advantage in place of the more conventional ACSR;having lower breaking loads than the latter,their use becomes particularly favourable when ice and win loadings are low.
AAAC (BS3242 Standard)
