63kV

63kV refers to a nominal voltage level of sixty-three thousand volts. This is a medium voltage classification within electrical power systems. In many countries, 63kV falls within the range of voltages used for sub-transmission and primary distribution networks. It serves as a crucial link between higher voltage transmission lines and lower voltage distribution feeders that supply electricity to end-users.

Systems operating at 63kV are typically found in areas where electricity needs to be transported over moderate distances, such as between substations or to industrial zones and large commercial buildings. The equipment used in these systems, including transformers, switchgear, and cables, is designed to safely handle and manage this voltage level. The choice of 63kV as a voltage standard is often influenced by factors such as power demand, geographical considerations, and established electrical codes and regulations within a specific region. It represents a compromise between the losses associated with transmitting power at lower voltages and the increased insulation and safety requirements of higher voltage systems.
