Electricity reaches every corner of urban and rural areas, bringing light and power to all. However, while electrical infrastructure benefits humanity, it also carries significant safety risks that cannot be ignored. Around high-voltage lines, transformers, switch stations, and other equipment, dangers such as high-voltage breakdowns, electric arc discharges, and step voltage are ever-present. If pedestrians or vehicles accidentally enter restricted zones, the consequences can range from equipment tripping to serious injuries or fatalities. Therefore, installing warning signs around power facilities has long been a standard safety measure.
Yet traditional warning signs are too "passive"—they merely hang on poles or fences, relying on people's awareness to notice them. At night, when lighting is dim, the warning messages become hard to read; during busy daytime traffic or hurried pedestrian movement, they are easily overlooked. Failure to detect these signs in time could lead to catastrophic outcomes.
To address this critical issue, Hizhuo Technology has introduced the HIZ-ST-JSQ High-Voltage Intelligent Voice Warning Device. Designed specifically for high-voltage environments such as transmission towers, power supply zones, distribution rooms, and substations, this device operates on the principle of "active sensing and intelligent voice alerts," transforming the passive nature of conventional warning signs.
Equipped with a highly sensitive radar sensor, the intelligent voice warning device accurately detects human presence or moving vehicles within its designated range. When approaching individuals or vehicles are detected near hazardous areas, the device immediately triggers a high-definition voice alarm, broadcasting customized warnings such as "High voltage danger—do not approach." This timely alert effectively interrupts distracted behavior and prevents accidental intrusions. To enhance visibility during low-light conditions at night, the device features active flashing warning lights that automatically illuminate after dusk, sending clear, attention-grabbing signals over long distances to warn passing vehicles and pedestrians, ensuring round-the-clock protection.
The intelligent voice warning sign uses a modular installation design, allowing easy mounting on tower crossarms, support structures, or walls without complex cabling, making it suitable for harsh outdoor environments. The audio content can be customized according to site requirements, and volume levels are adjustable—ensuring effective warnings while minimizing noise disturbance to surrounding communities.
