A draw-out metering element with voltage check function, also known as a withdrawable metering element with grounding, is a movable functional unit designed for armored withdrawable switchgears in a metal enclosure (for example, the common models KYN28A-12, KYN61-40.5, etc.). It combines the functions of checking the presence of voltage, grounding, insulation and others; The main purpose is to provide the operator with safe, reliable and convenient protection measures during system repair, prevent the risk of electric shock caused by erroneous operations, and strictly meet the "five lock" requirements for power systems.

This product generally adopts a composite insulation structure (such as air insulation with top and bottom insulation caps and contact arm insulation sleeves, or APG injection molded epoxy resin insulation cylinder), which has excellent insulation properties and mechanical strength.
