BS IEC 60826 is an international standard that discusses design criteria for overhead transmission lines. Overhead power lines are used to transmit and distribute electrical power over long distances, forming a power or national grid.
BS IEC 60826 specifies the loading and strength requirements of overhead lines derived from reliability-based design principles. These requirements apply to lines 45 kV and above but can also be applied to lines with a lower nominal voltage.
BS IEC 60826 also provides a framework for the preparation of national standards dealing with overhead transmission lines, using reliability concepts and employing probabilistic or semi-probabilistic methods. These national standards will need to establish the local climatic data for the use and application of this standard, in addition to other country-specific data.
Note: BS IEC 60826 does not cover the detailed design of line components such as supports, foundations, conductors or insulators strings.
BS IEC 60826 on overhead transmission lines applies to:
Overhead power lines are used to transmit and distribute electrical power over long distances, forming a power or national grid.
BS IEC 60826 provides design criteria for overhead lines based on reliability concepts. The reliability-based method is useful in areas where significant amounts of meteorological and strength data are readily available. This method is used for lines designed to withstand specific climatic loads, either derived from experience or through calibration with existing lines that had a long history of satisfactory performance. BS IEC 60826 also provides minimum safety requirements to protect people and construction/maintenance personnel from injury, as well as to ensure an acceptable level of service continuity (safe and economical design).
With obedience and compliance to BS IEC 60826, you can efficiently manufacture high-quality overhead transmission lines.
