AC High Voltage Acousto-Optic Voltage Detector

Acousto-Optic Voltage Detector Series

This series of contact-type acousto-optic voltage detectors is essential safety equipment for power maintenance and line operation, used to quickly verify whether lines and equipment are energized. With dual audible & visual alarm, the energized status is clearly identifiable, ensuring personnel safety. All models are equipped with self-test function to verify device status before operation and avoid misjudgment.

High Voltage Model (10kV~500kV) Suitable for voltage detection on HV overhead lines, substation equipment and distribution lines from 10kV to 500kV. The rod is pultruded from epoxy resin fiberglass with high insulation strength and bending resistance, telescopic design for portability and high-altitude operation. The end contact electrode delivers stable conductivity, with built-in anti-interference integrated circuit for accurate alarm triggering even in strong electric field environments. The limit ring defines the safe hand-holding range, and the moisture-proof & dust-proof sealed structure ensures stable performance in complex outdoor conditions.

Low Voltage Model (0.1kV~10kV) Suitable for voltage detection on low-voltage distribution systems, indoor switchgears and distribution station equipment from 0.1kV to 10kV. Optimized sensitivity design for low-voltage scenarios ensures accurate triggering even at weak voltage. The lightweight and flexible rod is ideal for operation in narrow spaces and indoor distribution scenarios. Clear audible & visual dual alarm effectively prevents low-voltage electric shock risks. Also equipped with self-test function for quick verification before operation, it is basic safety equipment for low-voltage maintenance and electrical work.
