摘要
厦门220kV春围Ⅱ路海底电缆首次在国内使用了大截面(2 500mm^2)、高电压(220kV)等级的自容式充油聚丙烯薄膜木纤维复合纸(PPLP)绝缘复合光纤电缆。介绍了该海底电缆的选型思路、电缆结构以及用于海底电缆敷设的自行设计的退扭系统,对海底电缆光纤测温、油压监测、海域视频监视等辅助系统进行了阐述。
In submarine cable of Xiamen 220 kV Chunwei Ⅱ, insulated composite optical fiber cable made of polypropylene laminated paper（PPLP）with big cross section（2 500 mm2 ）and high voltage level（220 kV）is first used in China. Selection thought and structure of the submarine cable, the self-designed system of retrograded torsion used for submarine cable＇ s laying are introduced. Auxiliary systems such as fiber temperature monitoring,oil pressure monitoring and sea area video monitor of the submarine cable are described.
