Electrical Transformer End-of-Life Hazardous Waste Removal use massive step-up transformers to increase voltage (aka tension) in order to push electricity more efficiently through long-distance transmission lines—hence the term "high tension wires." They use step-down transformers, for example, to reduce voltage to the relatively safe and familiar 120/220 VAC we have in our homes.
