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 tensilestrength is mostly used for this applicationStrand is installed at the top of steel tower and functions as a ground (earth) wireto protect the Aluminum Conductor with Steel reinforced (ACSR) from lightening

• With its normal lifespan of 20 to 30 years, thick Galvanized layer better than orequivalent 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
• 1x7 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  apoly-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 19construction strands are used

• As guying wire (for poles and towers)
• Used as guying wire for various poles, towers for power and Telecom Cables, theIndustry 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
