The reliable, uninterrupted transmission of electrical power is vital to the electric utility industry. Transmission lines carrying large blocks of power must be permanently protected against damage from lightning or the occasional fault. AFL Alumoweld overhead ground wires, also referred to as shield wires, provide the best means of obtaining this protection. They combine conductivity, corrosion resistance, and high strength–all of the properties necessary for such assurance.
The thick aluminum cladding on each wire offers optimum protection against atmospheric corrosion while providing the conductivity important for proper operation of protective relays. The high conductivity of Alumoweld strand also reduces the temperature rise of the static wire under fault current conditions.
