Projects for Insulation of High Voltage Power Lines
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.
