I. Requirements Analysis

The increasing urban infrastructure development and frequent use of heavy machinery such as cranes and loaders pose external damage risks to power transmission lines, severely compromising their operational reliability. To prevent accidental entry into energized high-voltage zones—which could lead to electric shock, line failures, fires, or power outages—our company has introduced high-voltage line anti-collision warning balls in response to the critical need for external force protection along transmission lines.

II. Working Principle

High-voltage line anti-external damage warning balls are installed on overhead high-voltage transmission lines as markers to indicate danger and provide warnings. This product is directly mounted on the conductors of overhead transmission lines, emitting a flashing red warning signal to mark the line. This enables passing pedestrians and vehicles to detect the danger early and take timely precautions, thereby reducing the occurrence of power grid safety incidents. The product emits an audible alarm when detecting approaching objects, preventing high-voltage accidents caused by operational errors from aerial work vehicles such as cranes and hoists.

III. Features and Functions

1. Audible and Visual Alarm: This product operates at the same potential as the live circuit, ensuring simple and reliable use without compromising the safe operation of the installed circuit. When power is present, the device's LED flashes; when power is absent, the LED remains steady.

2. Long service life and excellent performance: This product employs anti-corrosion and anti-rust technology, maintaining consistent performance under complex climatic conditions such as rain, snow, ice, and oil exposure. It boasts a long service life and outstanding performance.

3. Detection Range: This product has a detection range of 3-6 meters, factory-adjustable, with an alarm sound exceeding 95 dB.

4. Scope of Application: This product is suitable for transmission lines ranging from 10kV to 500kV, offering broad applicability.
