Trend is moving towards using ABC cables in place of underground cable in power distribution network. ABC are much lighter, economically feasible and higher current rating of at least 10 % more than underground armoured cables. ABC are either Low Tension or High Tension Grade. ABC aluminium conductors are mainly XLPE insulated and each core are twisted round a aluminium alloy bare stranded conductors called MESSENGER. The Messenger conductor facilitates suspension of the cable on hooks and clamps in street lighting poles.
