Projects for Insulation of High Voltage Power Lines

Dr. Giobbe graduated in electrical engineering from Genoa University and has been an expert in overhead line insulation since the 1980s. A speaker at several past INMR WORLD CONGRESSES, he is a qualified member of EB Rebosio’s design and technical department, with primary focus on composite insulators. This sector is a branch company of Gruppo Bonomi – a manufacturer of electrical components for railways as well as medium voltage and high voltage applications.

These days, insulator manufacturers are increasingly being called upon to develop, manufacture and test new overhead line concepts, based on specific user requirements. Often, the special requirements relate to either a challenging service environment or to the need for a compact design solution either to help reduce costs or to facilitate approvals for a new line project. This presentation describes the complete development and approval phases of projects carried out around the following line designs: a 132 kV insulating bracket for application in a polluted area with a high concentration of salt spray; and a 400 kV insulating bracket for a new compact overhead line.
