ABOUT DILLON IN UTILITY
While erecting an overhead line, it is very important that the conductors are under a safe tension.
If the conductor wires are too stretched between supports in a bid to save conductor material, the stress in the conductor can reach unsafe value and in certain cases may break due to excessive tension. Over tensioning of the conductors also puts great strain on the supporting poles, which can result in their collapse in extreme weather conditions. In order to permit safe tension in the conductors, they are not fully stretched but are allowed to have a dip or sag. In an overhead line, the sag should be adjusted so that tension in the conductors is within the recommended safe limits. The tension is governed by the conductor weight, effects of wind and ice loading plus ambient temperature variations. It is a standard practice to keep conductor tension at less than 50% of its ultimate tensile strength i.e. minimum factor of safety in respect of conductor tension. Ensuring you have the conductor under the correct tension will increase service life and reduce overall maintenance costs by minimizing fatigue and storm damage.
Due to the nature of electrical construction industry work, The American Line Builders Joint Apprenticeship & Training Committee (ALBAT) apprentices learn their career skill through practical, “hands-on” training, reinforced by classroom instruction. With courses covering topics such as Rigging Essentials and OSHA 10 Electrical Transmission and Distribution, it is important that the apprentices have hands-on experience of the tools and equipment used in the trade.
