STANDARDIZED TOWER FOR EMERGENCY USE AND COMPACT LINES IN SWITZERLAND

, , and .
(1991)

Abstract

In a first part design and use of a special tower is described. This tower was developped in the late seventie9 and based on the following principles: applicable for voltage levels between 50 kV and 400 kV, tower heights up to 60 m, reasonable storage room requirements,limited weight of individual elements (helicopter transport) , easy and fast erection, appropriate for re-use. The advantage of such a tower is to arrange within a short period of time a provisional tower replacement in case of a tower failure due to any reason. The use of the so-called emergency tower is manyfold. As a single steelpole with bolted elements various tower heights can be chosen. The weight of individual elements is limited as to enable helicopter transports. Insulated crossarms take into account the normally limited space available. A second part of this report deals with a few aspects regarding compacted towerconfiguration and compact lines in Switzerland.
