What is the voltage for DWP Primary lines?

The voltage for DWP (Department of Water and Power) primary lines is typically 4.8 kV. This voltage level is commonly used for distribution systems to deliver electricity from substations to smaller lines that serve neighborhoods and commercial areas. It is designed to balance the efficiency of power transmission with the requirement for safety and equipment compatibility.

Higher voltage levels, such as 34.5 kV, 138 kV, and 230 kV, are generally utilized for transmission lines that cover longer distances and are responsible for moving large amounts of power over regional areas. These voltages are more appropriate for high-voltage transmission systems, which are distinct from the lower voltage primary distribution lines utilized for direct delivery to consumers. Thus, understanding the specific context of primary lines as related to DWP leads to the conclusion that 4.8 kV is indeed the correct answer.
