Chonghong Industries Ltd

Model Number: CHCS201501012-#4555 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 againstlighting1 x 7 construction strand with grade A galvanization and withgroup one tensile strength is mostly used for thisapplicationsStrand installed at the top of steel tower and functions as aground (earth) wire to protect the aluminum conductor with steelreinforced (ACSR) from lighteningWith its normal lifespan of 20 to 30 years, thick galvanizedlayer better than or equivalent to that of galvanized strand forACSR 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 Agalvanization are widely used for this application

The telecoms cable and galvanized strands are coated togetherwith 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 andtelecoms cables, the industry is moving towards using higherstrength strands with better corrosion protection for thisapplications

Used for ACSR (aluminum conductor steel reinforced)

Used to support ACSR cable as the core strength member, forpower cables with above 60kV capacity, ACSR is widely used inreplacement of hard cu-strand conductors, in comparison with hardCu cables, ACSR weighs 20% less with 1.7 times increase in strengthso that the interval between power transmission towers can bedoubled
