Limits RegistryPUBLIC RECORD
Limits RegistryThe Soviet Ekibastuz–Kokshetau line in Kazakhstan was operated at 1,150 kV AC from 1985, the highest AC transmission voltage ever used commercially; it was later downrated to 500 kV. China's 1,000 kV UHV AC network is the highest-voltage AC system in operation today. (Distinct from DC lines such as China's ±1,100 kV Changji–Guquan link.)

The Soviet Ekibastuz–Kokshetau line in Kazakhstan was operated at 1,150 kV AC from 1985, the highest AC transmission voltage ever used commercially; it was later downrated to 500 kV.

The highest alternating-current voltage at which a commercial transmission line has been operated.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.

Only accepted Claims matching the current specification contribute to the displayed bounds. Strict inequalities remain open; contradictory Claims require editorial review.
