Aluminium wire (AL1) is used in low, medium and high voltage lines.
They are widely used in urban areas where the span length is typically short and high conductivity is required. The aluminium’s high corrosion resistance, make aluminium conductors a good choice in coastal areas. Because of its relatively low strength to weight ratio, aluminium conductors are of limited use in transmission lines and rural distribution lines, where long span lengths are often used.
Additional corrosion protection is available through different grease alternatives.
