    Recently, the type test of "domestic 500 kV cross-linked polyethylene submarine cable" has achieved phased results in Zhoushan, and the debugging test is being carried
    out.
    After the successful test of this submarine cable, it will break the current history
    of China's 500 kV submarine cable dependence on imports.

    Up to now, there is no domestic production capacity of 500 kV submarine cable, and technology and products mainly rely on imports
    .
    In order to promote the localization of submarine cables, several domestic submarine cable manufacturers have recently manufactured 500 kV submarine cables, in order to put into production and operation
    after the test passed by authoritative institutions.

    The Marine Transmission Technology Research Center of State Grid Zhoushan Power Supply Company, which undertook this test task, has been named the State Grid Corporation's Marine Transmission Engineering Technology Laboratory and has become a domestic laboratory with submarine cable testing capabilities
    .
    The relevant person in charge of State Grid Zhoushan Power Supply Company pointed out that the company will rely on the marine transmission engineering technology laboratory and cooperate with the power industry electrical equipment quality inspection and testing center to take the lead in carrying out 500 kV submarine cable type test
    in China.

    It is reported that the domestic 500 kV submarine cable after passing the test will first be applied to the
    500 kV Zhoushan and mainland interconnection project.
    The project is the largest and most difficult 500 kV cross-city interconnection project in the history of Zhejiang power grid construction, with a new submarine cable route of 17 kilometers, the submarine cable will use domestic 500 kV submarine cable, and after completion, it will become a world-class AC 500 kV polyethylene insulated submarine cable project
