In the power transmission system, hot sticks are key tools that ensure the safety and efficient operation of line operations. They are made of Fiberglass materials, such as fiberglass-reinforced plastic, which is not only lightweight but also has excellent electrical insulation properties, capable of withstanding high-voltage impacts up to tens of thousands of volts. This special material builds a solid safety barrier between operators and live equipment, making them indispensable protective equipment during live working, especially in high-voltage scenarios where even a tiny mistake could lead to fatal consequences.
In power transmission, operations such as opening and closing line switches, knife switches, and disconnecting links are very frequent. Thanks to their adjustable length design, which can usually be extended from 1 meter to 5 meters or even longer, hot sticks can adapt to power towers and equipment of different heights, whether it is a low-voltage distribution pole or a high-voltage transmission tower. This allows operators to complete operations without close contact with live parts, thus effectively avoiding the risk of electric shock. Especially during maintenance of high-voltage transmission lines or emergency fault handling, such as sudden short circuits or equipment failures, they can quickly respond to operational needs. For example, when a section of the line needs to be isolated urgently, workers can use hot stick to operate the corresponding switches from a safe distance, ensuring timely connection and disconnection of lines and reducing the duration of power transmission interruptions, which is crucial for minimizing economic losses caused by power outages.
The insulating performance of hot sticks has undergone strict testing, including high-voltage withstand tests, mechanical strength tests, and environmental adaptability tests, enabling them to work stably in high-voltage environments of tens of thousands of volts. Their smooth surface can reduce dust accumulation and prevent moisture absorption, ensuring long-term insulating effects. In complex outdoor environments, whether in rainy, snowy weather, extreme heat, or cold, hot stick can maintain structural stability. The material is resistant to corrosion and aging, so even after long-term use in harsh conditions, it will not easily lose its insulating properties, ensuring that operations are not affected by the environment.
In addition, the lightweight nature of the hot stick enhances operational flexibility. Compared with traditional heavy metal tools, they are easier to carry, which is particularly important for workers who need to climb poles or walk long distances in the field. In the maintenance of transmission lines in complex terrains such as mountains and hills, they are easy to carry and operate and can adapt to field working environments. With the help of a hot stick, workers can easily complete tasks such as switching operations and line switching, greatly reducing labor intensity and improving work efficiency. They provide solid support for the stability and continuity of power transmission and are an important guarantee for the safe operation of the entire power system, playing an irreplaceable role in ensuring the smooth transportation of electricity from power plants to thousands of households.
