What voltage is typically used to test the insulated stick portion of hot-line tools?

The typical voltage used to test the insulated stick portion of hot-line tools is 50,000 volts per foot. This level of voltage is established based on safety standards that ensure the tools can withstand the electrical stresses they may encounter in the field. Insulated tools, such as hot-stick devices, are critical for protecting workers from electrical hazards while they perform maintenance or repairs on live electrical lines.

By testing at this voltage, the insulation material is evaluated for its capability to prevent electrical breakdown, ensuring that it can safely handle the voltages it may be exposed to during operations. The emphasis on this specific voltage reflects an industry standard aimed at maintaining worker safety and tool reliability in high-voltage environments. Testing at higher voltages, such as the options provided that exceed 50,000 volts per foot, is generally unnecessary for the functional testing of these tools and may not align with standard practices or regulatory requirements.
