- This 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 utilise climatic data, since sufficient information is often not available in existing building codes and standards. In particular there is a lack of information on ice loads. The objective of this report is met by: a) reporting on the availability and proper use of climatic data b) recommending simple standardized measurement techniques c) reviewing icing models for computing ice loads. The details of each of the foregoing aspects of overhead line design loads are presented in the following clauses. Clause 3 describes the framework - or strategy - linking these separate aspects together.
