Underground, submarine and superconducting cables: Relationships
Every element and industry that Underground, submarine and superconducting cables is linked to, and how. Each pair has its own card explaining the relationships between the two.
- Aluminium: Buried and subsea power cables need a metal conductor, and aluminium competes with copper for it: aluminium needs a larger cross-section for the same rating but is far lighter and usually much cheaper, so the copper to aluminium price gap decides the choice for many projects. (researched)
- Offshore wind: Every megawatt-hour from an offshore wind farm reaches land through subsea export cables, so a few cable makers with factories booked into the late 2020s, and the risk of a single cable fault, set how fast and how reliably offshore wind can grow. (researched)
- AC transmission: Energy flows from underground, submarine and superconducting cables to AC transmission; their prices have moved together.
- Copper: Underground, submarine and superconducting cables needs copper; their prices have moved together.
- HVDC links: Energy flows from underground, submarine and superconducting cables to HVDC links; their prices have moved together.
- Distribution grids, mini-grids and interconnectors: Energy flows from underground, submarine and superconducting cables to distribution grids, mini-grids and interconnectors.
