Steel Wire, Used for Train Railroads, Streetcar Lines, Subway Railroads and More

Galvanized steel strand stay wire and aerial earth wire for BS 183, ASTM IEC 888 1 x 7, 1 x 19 and 1 x 37 mm

Overhead ground (or static) wire (for protection against lighting)

1 x 7 mm construction strand with grade- A galvanization

With group- 1 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 reco mm ended

For teleco mm unication cable (self- supporting type)

Used to support self- supporting (S. S) teleco mm unication cable, which has replaced obsolete lead plated cables

1 x 7 strands with group- 1 tensile strength and grade- A galvanization are widely used for this application

Teleco mm unications cable and galvanized strands are coated together with a polyethylene insulation

Messenger wire to support utility lines

Used at train railroads, streetcar lines and subway railroads

Either 1 x 7 or 1 x 19 mm construction strands are used

As guying wire (for poles and towers)

Used as guying wire for various poles and towers for power cables and teleco mm unications cables

Industry is moving towards using higher strength strands with better corrosion protection for this application

For ACSR (aluminum conductor and steel reinforced)

Used to support ACSR cable as the core strength member

For power cables with above 60kW 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
