Cabling renovation concept in large‐scale renovation of rural area networks

Purpose – Underground cabling has become a true alternative in construction of electricity distribution networks, even in rural areas. The increasing amount of underground installations requires strategic work that helps to define the most profitable cabling targets. The purpose of this paper is to introduce a methodology to consider the underground cabling process.Design/methodology/approach – The paper proposes a cabling concept that covers the issues on how cabling should be carried out. The analysis is based on techno‐economic and reliability analyses. The methodology consists of several steps that together constitute the concept.Findings – The underground cabling concept comprises several steps that can be simplified into questions: where, what, when and how the network cabling process is carried out. The analysis of these questions and the related features of the network show that different approaches to the renovation can cause significant differences in profitability between the renovation strateg...
