  • IEEE Guide for Maintenance Methods on Energized Power Lines - Redline
    … should be used. a) Gloves – ASTM D 120 and IEC 60903 b) Sleeves – ASTM D … The dielectric strength is defined as the voltage per-unit length (kilovolt/foot or kilovolt/meter) of the insulating part of the tool or equipment. In the late 1950s, most of the tool manufacturers switched from wood to fiberglass -reinforced plastic (FRP) materials that have a high dielectric strength and do not absorb moisture as easily.
