Image
  In China's electrical power industry, voltage levels play a critical role in determining the type of cables used and their applications. Common voltage grades include 220V, 380V, 1kV, 10kV, 35kV, 110kV, 220kV, and 500kV. These are broadly categorized into three groups: low voltage, medium voltage, and high voltage. This article explores the differences between low-voltage and high-voltage cables, their structures, uses, production processes, and how to distinguish them in practice. Voltage Classifications in China Low Voltage (LV):  Typically 220V and 380V, primarily used for household electricity and small-scale applications. Medium Voltage (MV):  Ranges from 1kV to 35kV, serving as an intermediary for industrial and local distribution networks. High Voltage (HV):  Starts at 35kV and above (e.g., 110kV, 220kV, 500kV), mainly employed for long-distance power transmission. These classifications dictate the design and construction of cables to ensure safety and effic...
