Why Power Lines Use 400 kV, Not 1,000 kV?

Why don’t transmission lines simply use 1,000 kV if higher voltage reduces losses?

✓ Higher voltage reduces current and conductor losses
✓ But very high voltage increases corona discharge
✓ Towers, insulators, air clearance, and switchgear become much larger
✓ Wider right-of-way corridors increase land and construction cost
✓ Engineers choose the best balance between efficiency and infrastructure cost
