APPLICATION OF FIBER GLASS REINFORCED POLES (FRP) IN MEDIUMVOLTAGE NETWORK IN EGYPT

摘要

The excellent electrical insulation properties of FRP) fiber glass reinforced pole) combined with their high strength makes them the preferred choice for many electrical and telecommunication applications. Transmission and distribution poles built from FRP are characterised with low maintenance, ease of installation, light weight and non conductive material. This study is carried out on two FRP poles of different dimensions. One of them(of lower dimensions) was subjected to vertical loads which are due to the weight of the conductors, insulators and pole, and to transverse loads which are due to wind during normal operation. Whereas, the other pole (of higher dimensions) was subjected to loads during emergency cases [1, 2]. For a better understanding of the behaviour of the FRP pole, the loads and deflections in the pole are recorded under the load application and load removal at steps of 100Kg. Photographs were also taken for the pole at every stage of applying and removing the load and finally in case of the pole failure. The results of this study are expected to contribute for better design of FRP poles running in desert areas.
