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 a dual audible & visual alarm, the energized status is clearly identifiable, ensuring personnel safety. All models are equipped with a 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. The rod is pultruded from epoxy resin fiberglass with high insulation strength and bending resistance, with a telescopic design for portability and high-altitude operation. The built-in anti-interference integrated circuit ensures accurate alarm triggering even in strong electric field environments. A 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 low-voltage distribution systems, indoor switchgears and distribution station equipment. Optimized sensitivity ensures accurate triggering even at weak voltage. The lightweight, flexible rod is ideal for narrow spaces and indoor scenarios. The clear audible & visual dual alarm effectively prevents low-voltage electric shock risks.
