Marine and offshore environments pose some of the harshest conditions for electrical systems. From deep-sea oil exploration to offshore wind farms, the need for reliable and durable electrical cables is paramount. Marine and offshore cables are specifically designed to withstand the unique challenges of these environments, such as extreme temperatures, high pressures, salinity, mechanical stress, … Read more

Chilean Government and Google Announce Partnership to Build First Submarine Cable Connecting South America to Asia-Pacific

Chilean President Gabriel Borich delivered a speech on the construction of submarine fiber optic cable at the Asia-Pacific Economic Cooperation (APEC) CEO Summit on November 15, 2023, in San Francisco, California.

The Chilean government on Wednesday (January 10) announced a partnership with Alphabet’s Google to build the first-ever undersea cable route directly connecting South America and the Asia-Pacific region. The submarine cable line is named “Humboldt”.

According to a Chilean government press release, Humboldt will connect the central Chilean port city of Valparaiso to Sydney, Australia, via 14,800 kilometers (9,200 miles) of fiber optic cable through French Polynesia. The capacity is 144 terabytes (TB) and the service life is 25 years.

Why Can only Submarine DC Cables be Used for Long-Distance Submarine Power Transmission?

ZMS high-voltage XLPE DC submarine cable development and technological innovation

The fundamental reason: the capacitive current of AC cables limits their transmission distance. This is for long-distance submarine projects, the transmission of large power is very difficult. Submarine DC cables have no capacitive current, transmission capacity is not limited by distance. So only a DC cable can be used to transmit power.

From the beginning of last year until now, the Russian-Ukrainian conflict, the Palestinian-Israeli conflict and so on broke out one after another. In these wars and conflicts, aerial cables, concentric cables, submarine cables and so on all play different degrees of important role.
