Feasibility Study for High-Strength Spun Concrete Pylon Prestressed with Carbon Fiber Reinforced Plastic for Transmitting Voltages at 110 kV Level

Abstract

The aim of this project is the production of a 28 m high carbon fiber reinforced plastic (CFRP) prestressed spun concrete pylon as a support for electric lines at the 110 kV voltage level (Duralight concept). It is intended to use this pylon as a support mast in a section of the 110 kV line of the Nordostschweizerische Kraftewerke (NOR, Power Company of North East Switzerland) beznau-Baden. The fundamental advantage of this new design is the low weight in combination with an optimum corrosion resistance. This paper describes the technical fundamentals studies in a four year research program at the Swiss Federal Laboratories for Materials Testing and Research EMPA for designing and manufacturing this prototype pylon. The presented pilot project results from a close co-operation of the spun concrete element production plant SACAC and EMPA and the power company NOK.
