The comparative study on the use of lattice towers versus conical monopods in SNEL SA’s high-voltage transmission network is of paramount importance in determining the conditions for safety, reliability, operation and maintenance. The main aim is to overcome the growing phenomenon of vandalism, such as the theft of galvanized angles, bolts, copper conductors and earth counterweight wires from electrical infrastructures, which leads to the collapse of lattice towers and the unavailability of SNEL SA’s power transmission lines. The use of polygonal monopole towers offers the following advantages: aesthetic, can be installed in urban areas, small footprint, one-day installation, reduced number of parts for assembly, low maintenance costs spread over several years, resistance to acts of vandalism, no natural aggression and environmental impact. The complete construction cost of one kilometer of line (ratio) is 1.25 k€/km for the conical monopod as opposed to 1 k€/km for the lattice tower, i.e. a 20% difference in investment.
Author Keywords: Comparison, use, lattice tower, conical monopole, SNEL SA High Voltage transmission system or grid.

Abstract
The comparative study on the use of lattice towers versus conical monopods in SNEL SA’s high-voltage transmission network is of paramount importance in determining the conditions for safety, reliability, operation and maintenance.

Abstract: (french)
L’étude comparative relative à l’utilisation des pylônes à treillis par rapport à ceux en monopodes de forme pylygonale dans le réseau de transport à haute tension de SNEL SA, est d’une importance capitale pour déterminer les conditions de sécurité, fiabilité, exploitation et maintenance. L’intérêt majeur est de vaincre le phénomène recrudescent des actes de vandalisme tels que de vol de cornières galvanisées, boulons, conducteurs en cuivre et fil de contrepoids de terre sur les infrastructures électriques qui conduisent à l’écroulement des pylônes à treillis, et indisponibilité des lignes de transport d’énergie électrique de SNEL SA. L’usage des pylônes monopodes de forme conique offre les avantages suivants: Esthétiques, peut-être implanté en zone urbaine, faible emprise au sol, installation rapide, démontage et réutilisation possible, une journée d’installation, nombre de pièces réduit pour l’assemblage, coût de maintenance faible étalé sur plusieurs années, résistance aux actes de vandalisme, pas d’agression naturelle et impact environnemental. Le coût complet pour construire un kilomètre de ligne est de 1,25 k€/km avec un monopodes conique, contre 1 k€/km pour un pylône à treillis, engendrant ainsi une variation de coût de 20 %.
Author Keywords: Comparaison, viabilité technico-économique, pylône à treillis, pylône monopodes de forme conique, réseau de transport électrique HT de SNEL SA.
