The conventional method of increasing the current carrying capacity of the submarine cable landing section increases the manufacturing cost of the submarine cable and the long-term operational reliability. This paper introduces the unequal diameter cable joint technology and checks and analyzes the actual current-carrying capacity of the 220 kV submarine cable landing section and the submarine section. Also， it proposes a differentiated unequal diameter submarine cable landing section and submarine section conductor cross-section matching principle and evaluates the economic efficiency of the unequal diameter cable matching scheme. The research results show that the larger the conductor cross-section of the submarine cable， the greater the drop in current-carrying capacity during the landing section. In the unequal diameter matching method， the single-core or copper wire armored submarine cable requires a smaller conductor cross-section. The maximum transmission capacity can be obtained when the submarine cable line is all single-core copper wire armored. When it is all single-core steel wire armor， it can take account of the larger transmission capacity of the submarine cable line and the optimal unit capacity cost. |
