What voltage is used for DWP Subtransmission lines?

Subtransmission lines are typically utilized to transport electricity from high-voltage transmission systems to distribution systems and local substations. In the case of DWP (Department of Water and Power) Subtransmission lines, a voltage of 34.5 KV is commonly used. This voltage level strikes a balance, allowing for efficient energy transfer while being low enough to support distribution without excessive losses or requiring highly robust equipment typically used for higher voltage levels, such as those found in the hundreds of kilovolts.

The choice of 34.5 KV for subtransmission helps in connecting the bulk power supply from transmission networks to the distribution network, ensuring local areas receive power at a manageable and usable voltage while remaining efficient in terms of energy loss over the distances involved. This voltage is also compatible with widespread distribution equipment, facilitating effective service delivery in various urban and rural settings.
