Live-line tools, rods, tubes, and poles made of fiberglass-reinforced plastic (FRP) must withstand what voltage for five minutes?

Live-line tools, rods, tubes, and poles made of fiberglass-reinforced plastic (FRP) are specifically manufactured to handle high voltages safely. When it comes to the voltage requirement for these tools, they need to withstand 100,000 volts per foot for a duration of five minutes to ensure safety and reliability in high-voltage environments. This high standard is crucial for protecting electrical workers from electrical shocks and ensuring that tools do not conduct electricity during live-line work.

The materials used in these tools, such as FRP, have excellent insulating properties, making them suitable for use in various electrical applications. The ability to withstand such high voltages for an extended period indicates that they can provide a safe working environment for linemen and electricians working on energized parts of the electrical distribution system.

Understanding this voltage threshold is essential for ensuring that the appropriate tools are used in the field, contributing to the safety standards mandated by industry regulations. Using tools that do not meet this requirement could lead to severe consequences, including electrical accidents or fatalities. Thus, the emphasis on 100,000 volts per foot reflects the critical nature of safety in live-line work.
