AlMgSi (AL7) – AAAC
AlMgSi (AL7) – AAAC
AlMgSi-alloy (AL7)-AAAC is designed to have a higher strength to weight ratio and provides improved electrical properties, excellent clamping properties and superior corrosion resistance compared to ACSR. This has given the AlMgSi-conductor broad acceptance in power distribution grids.
Additional corrosion protection is available through different grease alternatives.
AAAC Al Aluminium Alloy conductor
AAAC General information
AAAC conductors are composed of several aluminium alloy wires (Al-Mg-Si) stranded over each layer. Most common AAAC conductors are composed of7, 19, 37,61 and 91 wires. AAAC conductors are also used as suspension wire and neutral on 0,6-1kV overhead insulated distribution cables.
AAAC Applications
Substations, Electricity Distrubition Lines, Electricity Transmission Lines . 0,6-1kv Overnead Bundled insulated Aluminium Cables
