Model Number: CHCS20160321 Brand Name: CHONGHONG Key Specifications/Special Features: Aerial earth wire for BS 183, ASTM IEC 888 1 x 7, 1 x 19 and 1x 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 applicationsStrand installed at the top of steel tower and functions as aground (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 recommended

For telecommunication cables (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 Galvanization are widely used for this application

The telecoms cable and galvanized strands are coated together with a poly-ethylene insulation

As messenger wire to support utility lines

Used at train railroads, streetcar lines and subway railroads, 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 telecoms cables, the industry is moving towards using higher strength strands with better corrosion protection for this applications

Used for ACSR (aluminum conductor steel reinforced)

Used to support 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
