High Voltage Project Engineering

High Voltage Project Engineering is the starting point for HV projects. In this department, the customer request is studied and technical solutions towards this request are defined and could comprise many different disciplines like the definition of the propriate cables and accessories, laying configuration, definition of the earthing method, the soil conditions, the functional requirements, the available norms and standards and the mechanical aspects. The correlation between the various aspects of a cable system makes the system design process an iterative process where experience and broad knowledge is mandatory.
