Description:
Overhead, ground (or static) wire (for protection against lighting)One x seven construction strand with Grade A galvanization and with group-1 tensile strength is mostly used for this applicationThe 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 lighteningTherefore, with 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 telecommunication cable, which has replaced obsolete lead-plated cables1 x 7 strands with group-1 tensile strength and Grade A galvanization are widely used for this applicationThe telecom cable and galvanized strands are coated together with a polyethylene insulationAs messenger wire to support utility linesUsed at train rail road, street car line and subway rail roadEither one x seven or one x 19 construction strands are usedAs guying wire (for poles and towers)Used as guying wire for various poles and towers for power cables and telecom cablesThe industry is moving towards using higher strength strands with better corrosion protection for this applicationFor ACSR (aluminum conductor steel reinforced)Used to support ACSR cable as the core strength memberFor power cables with above 60kV capacityACSR is widely used in replacement of hard Cu strand conductorsIn 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
