According to Zhongtian Technology Group, recently, the first domestic ±320 kV green polypropylene insulated DC cable and the first domestic 220 kV solid phase grafted PP insulated power cable jointly developed by Zhongtian Technology Submarine Cable Co., Ltd. have all passed type tests, which means that China's high voltage AC and DC fields also have self-developed green environmentally friendly cables. Deep sea wind power transmission and urban power grid upgrades have new localization solutions.
