AS/NZS Overhead Line Design Standard AS/NZS OVERHEAD LINE STANDARD Handbook HB published April 1 | Transmission Line Design Standard. Summary. This standard defines the performance design parameters for overhead transmission lines constructed to.

    The overhead line has to perform with suitable levels of reliability and security for the weather loads expected in the region for its intended life. Reliability levels All overhead lines should be designed for a selected reliability level relevant to the lines importance to the system including consideration of system redundancy , its location and exposure to climatic conditions, and with due consideration for public safety. Design Working and Service Life The design life, or target nominal service life expectancy, of the line is dependent on its exposure to a number of variable factors such as solar radiation, temperature, precipitation, wind, ice, and seismic effects. The service life of an overhead line is the period over which it will continue to serve its intended purpose safely, without undue maintenance or repair disproportionate to its cost of replacement and without exceeding any specified serviceability criteria. Structural components of the support must be able to withstand the ultimate design loadings without failure within this period. This may include providing allowance for a reducing load factor over time due to progressive degradation such as soft rot in timber pole elements and corrosion of steel elements. Security levels Clause 6. In this evaluation consideration must be given to the lines importance to the system including any system redundancy , its location, exposure to extreme climatic conditions, public safety and design working life.
