The history and development of INTERNATIONAL IEC STANDARD 61089.pdf




The INTERNATIONAL IEC STANDARD 61089.pdf was first published in 1991 as a result of the revision and consolidation of four previous standards: IEC 60207, 60208, 60209 and 60210. These standards were issued between 1971 and 1979 and covered different types of round wire concentric lay overhead electrical stranded conductors. The revision aimed to harmonize the specifications and requirements of these conductors and to update them according to the latest technological developments and market needs.


The INTERNATIONAL IEC STANDARD 61089.pdf was amended in 1999 to include some editorial changes and corrections. It also added a new annex on recommended conductor sizes and tables of conductor properties. The standard is currently under review by the IEC Technical Committee 7, which is responsible for software and systems engineering. The committee is expected to publish a new edition of the standard in the near future.


The applications and advantages of INTERNATIONAL IEC STANDARD 61089.pdf




The INTERNATIONAL IEC STANDARD 61089.pdf is widely used by manufacturers, suppliers and users of round wire concentric lay overhead electrical stranded conductors. These conductors are mainly used for power transmission and distribution lines, especially in rural areas where long spans are required. They can also be used for other purposes such as telecommunication lines, railway electrification lines, aerial earth wires, etc.


The INTERNATIONAL IEC STANDARD 61089.pdf offers several advantages for the users of these conductors. Some of them are:


  • They have high tensile strength and good corrosion resistance.



  • They have low electrical resistance and high current carrying capacity.



  • They have good flexibility and sag characteristics.



  • They have low cost and easy installation.



  • They have long service life and low maintenance.



The comparison and compatibility of INTERNATIONAL IEC STANDARD 61089.pdf with other standards




The INTERNATIONAL IEC STANDARD 61089.pdf is not the only standard that deals with round wire concentric lay overhead electrical stranded conductors. There are also other national and regional standards that have similar or different specifications and requirements for these conductors. Some of them are:


  • ASTM B232/B232M - Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)



  • BS EN 50182 - Conductors for overhead lines - Round wire concentric lay stranded conductors



  • DIN EN 50182 - Leiter für Freileitungen - Runddrahtlitzen



  • GB/T 1179 - Round wire concentric lay overhead electrical stranded conductors



The INTERNATIONAL IEC STANDARD 61089.pdf is compatible and harmonized with some of these standards, such as BS EN 50182 and DIN EN 50182, which are based on the IEC standard. However, there may be some differences or discrepancies between the IEC standard and other standards, such as ASTM B232/B232M and GB/T 1179, which have their own specifications and requirements for these conductors. Therefore, it is important to check the compatibility and equivalence of the standards before using them for your conductors.


The future trends and challenges of INTERNATIONAL IEC STANDARD 61089.pdf




The INTERNATIONAL IEC STANDARD 61089.pdf is a dynamic and evolving standard that reflects the current state of the art and market needs of round wire concentric lay overhead electrical stranded conductors. However, as the technology and demand of these conductors change over time, the standard also needs to adapt and improve accordingly. Some of the future trends and challenges that may affect the standard are:


  • The development of new materials and alloys for these conductors, such as aluminium-magnesium-silicon alloy (AlMgSi), which can offer higher strength, lower weight and better corrosion resistance than conventional aluminium alloys.



  • The improvement of the design and performance of these conductors, such as increasing their current carrying capacity, reducing their sag and losses, enhancing their thermal stability and durability, etc.



  • The integration of these conductors with other components and systems, such as optical fibres, sensors, smart grids, renewable energy sources, etc., which can offer new functionalities and applications for these conductors.
