Abstract Although several recent studies have shown how high voltage transmission (HVT) lines affect property values, no work has been undertaken in Zambia. This paper explores if there is a prima facie relationship between HVT lines and residential property values in Zambia. A priori evidence shows a paradox, with many new developments springing up in areas of high concentrations of HVT lines though residents vehemently complain about the mal-effects of HVT lines. Why then should land perceived to be inferior or “stigmatized” attract new developments? It is against this background that the householders’ perceptions of HVT lines are explored and the resulting effects on property values ascertained. A household survey was conducted in the Chalala, Libala South and Kamwala South areas of Lusaka city where developments have been undertaken around HVT Lines. The study also examined the statistical relationship of distances from HVT line with residential property values. Results show residential property values rise with increasing distance from the HVT line. It is recommended that the statutory wayleave distances should be raised to at-least 100 meters from the existing 31 meters for a 132kV line. It is further recommended that the regional wayleave guidelines currently in use should be made national.

Important Design

The paper deals with the towers of electric high voltage overhead lines. The target is a relatively simple suspension tower (tension support) made of hot rolled angles. The main aspects of structural design and the structural details are given due to the newly introduced design codes and the former Hungarian ones. The fundamental aim of the paper is to point out the changes according to the new developments. As an important design aid, a set of interactive programs developed by the authors is also shortly introduced.
