· Aerial earth wire for BS 183, ASTM IEC 888 1 x 7, 1 x 19 and 1 x 37
· As overhead ground (or static) wire for protection against lighting
· 1 x 7 construction strand with grade A galvanization and with group one tensile strength is mostly used for this application
· Strand is installed at the top of steel tower and functions as a ground (earth) wire to protect the aluminum conductor with steel reinforced (ACSR) from lightening
· With its normal lifespan of 20 to 30 years, thick galvanized layer better than or equivalent to that of galvanized strand for ACSR is recommended
· For telecommunication cable (self-supporting type)
· Used to support self-supporting (SS) telecommunication cable, which has replaced obsolete lead-plated cables
· 1 x 7 strands with group one tensile strength and grade A galvanization are widely used for this application
· The telecom cable and galvanized strands are coated together with a poly-ethylene insulation
· As messenger wire to support utility lines
· Used at train railroad, streetcar line and subway railroad, either 1 x 7 or 1 x 19 construction strands are used
· As guying wire (for poles and towers)
· Used as guying wire for various poles, towers for power and telecom cables, the industry is moving towards using higher strength strands with better corrosion protection for this application
· For ACSR (aluminum conductor steel reinforced)
· Used to supports ACSR cable as the core strength member, for power cables with above 60kV capacity, ACSR is widely used in replacement of hard cu-strand conductors, in comparison with hard Cu cables, ACSR weighs 20% less with 1.7 times increase in strength so that the interval between power transmission towers can be doubled
