AC voltage detector HST-250

high-voltagemedium-voltagewaterproof

Product
HST-30 medium-voltage and high-voltage detector designed for live-voltage verification on medium and high voltage lines and equipment. Lightweight construction for field operability.

Voltage
AC
3 kV–34.5 kV

Features

• FRP insulating stick for reduced weight and improved handling.
• Tip metal fitting incorporates a shock-absorbing spring to mitigate impact.
• Operating rod can be extended to a longer length; shortening is not permitted for safety reasons.
