Professional Answer: As a prominent manufacturer and exporter of power line equipment, we understand that overhead line equipment operates at a wide range of voltages, each serving a specific purpose within the electrical grid. The voltage level is a critical factor in the design and selection of equipment, including the tension stringing equipment and tools we specialize in.

The main classifications are:

• Low-Voltage (LV): Typically below 1,000V. These are the final distribution lines that deliver electricity directly to homes, businesses, and streetlights. Our cable laying tools and accessories are essential for safely connecting these lines.

• Medium-Voltage (MV): Ranging from 1kV to 36kV. This is the local distribution network within cities, towns, and industrial areas, stepping down power from high-voltage lines. We provide a full range of overhead tools and accessories designed for safe installation and maintenance at these voltages.

• High-Voltage (HV): From 36kV up to 230kV. These lines are the backbone of the grid, transmitting large amounts of power over long distances between major substations. Our overhead transmission line equipment, including specialized stringing machines, is built for the demanding requirements of these projects.

• Extra-High-Voltage (EHV) and Ultra-High-Voltage (UHV): Exceeding 230kV, with UHV lines reaching 800kV and even higher. These are the most powerful lines, designed for super-long-distance transmission to minimize power loss. Our robust and innovative equipment is used in the construction of these critical, high-capacity corridors worldwide.
