Description
DESCRIPTION:
Two systems are available, namely:
SELF-SUPPORTING SYSTEM:
Consists of four cores of hard drawn stranded compacted aluminium conductors of the same
cross-sectional area insulated with Carbon loaded XLPE for UV protection
SUPPORTING CORE SYSTEM:
Consists of three phase cores of hard drawn stranded compacted aluminium conductors of
the same cross-sectional area insulated with Carbon loaded XLPE and laid up around a bare
aluminium alloy supporting core
APPLICATIONS:
ABC Cable is used in place of bare conductor overhead distribution systems. It provides a
higher level of safety and reliability and economy with reduced maintenance and operative
costs and reduced risks of vandalism and theft. It is ideal for difficult terrains and urban areas
and is a flexible system that is easier to reroute than the conventional overhead line methods Installation Information
