HVDC is used for long submarine cables where AC cannot be used because of cable capacitance.Donald G. Fink, H. Wayne Beatty, Standard Handbook for Electrical Engineers 11th Edition, McGraw Hill, 1978, , pages 15–57 and 15–58 In these cases special high-voltage cables are used. Submarine HVDC systems are often used to interconnect the electricity grids of islands, for example, between Great Britain and continental Europe, between Great Britain and Ireland, between Tasmania and the Australian mainland, between the North and South Islands of New Zealand, between New Jersey and New York City, and between New Jersey and Long Island. Submarine connections up to in length have been deployed.
