EVOLUTION OF THE DESIGN FOR THE 123-kV TRANSMISSION LINE OF OUDEHASKE - OOSTERWOLDE AND THE POSITION OF A 123/12 kV-STATION IN THIS LINE

, , , and . (1981)

Abstract

For an open landscape with little farms and houses in the north of the Netherlands an 123-kV transmission line should be designed. There were made high demands upon the visual impact of the line in this landscape. For this reason it was necessary to design a clean structure also in detail. Therefore the number and the size of the shape determining elements should be as low as possible. The result is a line with poles with hexagonal steel sections and a support shape with double circuit vertical formation. Conductors are used with a stress of 55N/mm2 at 10° conductor temperature, so that the mid span sag is as small as possible and with that the impact of the line in the environment. A 123/12 kV substation is positioned around a pole in this line, In this way it is more clear that the substation is a part of the line.
