This International Technical Report (type 2) aims at providing advice on methods for developing climatic load databases. This is necessary for the implementation of IEC 60826 which provides the framework for National Standards on overhead line design. However, for its practical use, it is required that design engineers acquire and utilize climatic data, since sufficient information is often not available in existing building codes and standards.
