TACSR Thermal-resistant aluminum alloy conductor steel core reinforced is used for overhead transmission lines, ground lines, and electric railways. Its significant advantages include corrosion resistance and high strength, making it suitable for long-span lines, areas with severe cold and heavy snowfall, and other harsh weather conditions besides general transmission lines. This conductor is particularly useful for capacity expansion and the upgrading of existing lines.
Thermal-Resistant Aluminum alloy conductor ,steel reinforced is a high ampacity conductor with inner core composed of Steel wire & outer layer composed of thermal resistant aluminium alloy with round.
