Underground Transmission Lines

Underground Transmission Lines are more common in populated areas. They may be buried with no protection, or placed in conduit, trenches, or tunnels.


Figure 13. Transmission lines are installed in a tunnel, which enables many circuits in a limited area.

Figure 17. Heat is generated when electricity flows through cables, limiting the power transmission capacity in tunnels. To increase the capacity, a tunnel cooling system can be installed. The system above circulates cold water through the tunnels.
