Guy wires can become energized through direct contact with live wires. When a guy wire comes into contact with an energized power line, it can create a direct path for electrical current, making the guy wire itself a conductor of electricity. This is particularly a concern in utility arboriculture, as maintaining distance from live wires is critical for worker safety and prevents accidental electrocution.

The insulation of guy wires does not typically protect them from becoming energized, as insulation is intended to prevent the flow of electricity in specific circumstances, not to shield from outside live currents or accidental contact. Indirect contact with grounded lines is also less likely to energize guy wires; rather, it could have the opposite effect by directing the electricity towards ground. Moreover, the statement that guy wires cannot become energized fails to recognize scenarios in which they are improperly managed or positioned close to energized conductors.
