| Aerial earth wire for BS 183, ASTM IEC 888 1 x 7, 1 x 19 and 1 x 37As overhead ground (or static) wire for protection against lighting1 x 7 construction strand with grade A galvanization and with group one tensile strength is mostly used for this applicationStrand 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 lighteningWith its normal lifespan of 20 to 30 years, thick galvanized layer better than or equivalent to that of galvanized strand for ACSR is recommendedFor telecommunication cable (self-supporting type)Used to support self-supporting (SS) telecommunication cable, which has replaced obsolete lead-plated cables1 x 7 strands with group one tensile strength and grade A galvanization are widely used for this applicationThe telecom cable and galvanized strands are coated together with a poly-ethylene insulationAs messenger wire to support utility linesUsed at train railroad, streetcar line and subway railroad, either 1 x 7 or 1 x 19 construction strands are usedAs 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 applicationFor 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 doubledAll trademarks shown here are for reference purposes only.
