Hitachi also demonstrates its ability to develop a 765kV EGLA for American Electric Power

This ambitious pilot project from AEP allowed the first-of-its-kind EGLA application for this voltage level. The financial consequences of lighting induced outages on such critical transmission lines are enormous. AEP is looking carefully at those innovations solutions to ensure stable and interrupted power supply and prevent grid instability. Furthermore, the increased reliability allows an increased supply capacity of electricity, a key argument for such UHV transmission lines.

Hitachi has opted for a solution with a rigid gap using an insulator. The overall EGLA set has the advantage of being simply connected to the conductor bundle through a clamping system.
