Prestressed Concrete Poles

Abstract

Electricity programmes enjoy top priority in many developing countries. Apart from the actual power generating, the provision of transmission lines and poles is the cornerpillar of the succesful realization of such a programme. The first poles used for the transmission of power and telecommunication were made of wood. Later, as requirements for poles increased, and with the limited-life of wood in view, poles were made of steel. Yet steel, although it has a comparatively longer life time than wood, is also subject to a considerable corrosion and thus requires careful maintenance over the years. Another and far more suitable material for poles is concrete.
