1. Product overview

It’s a strong flashing safety device directly installed on indoor high-voltage (10-35kV) electrical equipment to visually display whether the high-voltage electrical equipment has operating voltage. Through strong flashing, it visually displays the live status of the high-voltage equipment, ensuring the safety of operators.

2. Functions & features

· Equipotential design, and sensors and secondary power supply are not required

It uses electric field to obtain energy at the same potential as high-voltage equipment.

· Easy installation and maintenance free

It’s designed with dedicated spring clamps, which can be directly installed on high-voltage electrical equipment. It is in an equipotential state and it can be installed and removed under the premise of good isolation measures. This device is not affected by "over-voltage" and does not affect the insulation of high-voltage equipment to ground.

· Clear display, strong indication, and strong anti-interference performance

When the high-voltage equipment is of operating voltage, the device can accurately and reliably highlight the flashing LED; It can display in split phase, not affected by adjacent phase.

· Environmental durability

P65 protection class, wide temperature operation range from -15℃ to +70℃
