Beijing: An inter-island power transmission network in Zhoushan, Zhejiang province, which is the first in China to use land cables running beneath the ocean floor instead of traditional submarine cables to transmit electricity between islands, recently began operations.
Experts said the project marks another milestone in the country’s advancement of marine power transmission technology and further contributes to China’s offshore energy development.
The project uses a 10-kilovolt cable running from a preset channel that is 6m below the seabed in the northern waters of Zhoushan, Zhejiang province, and is 1km long. The cable runs from Zhoushan Island to Shangyuanshan Island.
State Grid Zhoushan Power Supply Co, the project’s developer, said that using cables buried beneath the seabed, instead of simply being placed underwater, can help solve problems like potential cable damage from ships’ anchoring and longer project approval time.
According to the company, at present, inter-island energy transmission mainly uses submarine cables. However, China’s coastal waters have busy shipping lines, which may damage submarine cables when ships anchor. — China Daily/ANN
