Recently, the power supply department of Yuhuan County implemented海缆Replace the project to provide electricity security for the economic and social development of Jishan Island. The expected investment for the submarine cable replacement project is over 5 million yuan, with a designed service life of 30 years and a power supply capacity twice that of the past.

At the construction site, the submarine cable laying ship is laying at a speed of 6 meters per minute along the pre designed path towards the stacking platform. It is reported that the "deep burial method" was used for this assignment. Through deep burial construction techniques, submarine cables can provide excellent protection.

In recent years, due to the aging of cable insulation layers and frequent external damage, multiple failures have occurred, seriously affecting the production and daily electricity consumption of island residents. To this end, the power supply department of Yuhuan has implemented the replacement project of the submarine cable from Zhantai to Jishan, replacing the original 120 square millimeter diameter submarine cable with a 240 square millimeter submarine cable. The expected investment for the submarine cable replacement project is over 5 million yuan, with a designed service life of 30 years and a power supply capacity that is twice that of the past.

Lin Yi, the general manager of Hongsheng Electric Installation Co., Ltd. in Yuhuan County, said that after the laying of this submarine cable, it will form a triangular loop consisting of Yangyu Island, Jishan Island, and Zhantai. In this way, if one cable malfunctions in the future, the normal power supply to the outlying islands of Jishan and Yangyu can also be ensured through another cable connection.
