3. Definitions, acronyms, and abbreviations
For the purposes of this document, the following terms and definitions apply. The IEEE Siandards Diclionaiy
Online should be consulted for terms not defined in this clause.
3.1 ADSS cable and hardware system definitions
breaking strength: The calculated maximum tensile load that the cable is estimated to reach upon mechanical failure. Mechanical failure is primarily associated with the cable strength member however other cable components may contribute to the overall strength. The maximum rated cable load is typically less than 60% of the breaking strength. Sin: breaking tension.
every day tension (EDT): The final tension with no ice and no wind at the average annual mean temperature throughout the year. This temperature is assumed as 16 °C (60 °F). This number is often used in specifying motion control devices such as vibration dampers.
NOTE—This is the same as the everyday tension when specified at 16 °C (60 °F).’
maximum loaded tension (MLT): The system tension that represents the tension above maximum installation tension (MIT) caused by environmental load conditions such as wind and ice. This tension shall not exceed the cable MRCL or the maximum tension allowed by the hardware (whichever is less). The load is greater than MIT but less than or equal to maximum rated cable load (MRCL). It is also referred to as maximum operating tension or short-term load. It may also be referred to as the National Electric Safety Code1 (NESCR) (Accredited Standards Committee C2-20 12 [131]) loaded tension, which corresponds with local regions across the United States that arc referenced in the NESC.
NOTE—For example. the MLT may be used in a case where the MRUL is higher than the expected loading on the cable (i.e., a stronger cable used than needed) and lower strength hardware is suitable.
4.3.3 Metallic welds
Welding shall be in accordance with AWS D 1.1 or an equivalent that meets or exceeds this standard. All welds shall be smooth, uniform, and without overlaps or excessive undercutting. Rough surfaces, scale, slag, and! or splatter shall he removed by grinding, sanding, or other acceptable practices. Distortions and stresses, if occurring due to welding, shall be properly corrected. Welders and welding operators shall be qualified in accordance with AWS Dl. I or an equivalent that meets or exceeds this standard. Proper stress relief methods shall be employed where necessary.
4.3.4 Corrosion resistance protection
Adequate corrosion resistant treatment per 4.4 shall he applied to all ferrous materials as agreed upon by the customer and manufacturer. Special requirements are necessary for threaded fasteners. If no other specifications are referenced, ferrous materials shall be hot-dip galvanized in accordance with ASTM A 153 or Iso 1461, or equivalent.
4.4 Environmental corrosion
The hardware shall be able to withstand the natural elements that exist at its installation location. The corrosive nature of installation sites can vary vastly from location to location. Therefore, some hardware designs are more suitable for certain locations than other designs. High corrosion sites such as high-moisture zones, salt water zones, industrial corrosion zones, volcanic sulfur zones, or combinations of zones require special protection from corrosion for the hardware.
