## High-Capacity 400 kV Overhead Transmission Lines

The transmission corridor features 2 redundant 400 kV circuits spanning 140 km designed for ambient desert temperatures exceeding 50 °C.

Quad-bundle high-temperature low-sag conductors minimize line impedance and prevent conductor sag under peak transmission loadings.

## Substation Protection and Dynamic Monitoring

High-speed busbar protection and phasor measurement units have been commissioned across 4 terminal switching stations.

Real-time dynamic line rating sensors provide transmission dispatchers with continuous thermal headroom analysis under varying weather conditions.
