ACSR | |
---|---|
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. |
Overhead Ground Wire | |
---|---|
1 x 7 construction strand with Grade A Galvanization and with Group 1 tensile strength is mostly used for this application. The strand is installed at the top of steel tower and functions as a Ground Wire to protect ACSR from lightening. |
Communication Cable | |
---|---|
Support Self-Supporting(S.S) telecommunication 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. The telecom cable and Galvanized strands are coated together with a Poly-Ethylene insulation. |
Messenger Wire | |
---|---|
Train railroad, streetcar line and subway railroad. Either 1x7 or 1x19 construction strands are used. |
Guying Wire | |
---|---|
Various poles and towers for power cables and telecom cables, etc. The industry is moving towards using higher strength strands with better corrosion protection for this application. |
