摘要
三林变电站至静安变电站的国内第1条长距离、大截面500 kV电缆线路,在上海首次应用。介绍了500 kV电力隧道的总体布置,阐述了500 kV电缆具特殊的敷设要求,就电缆线路在隧道内的排列形式、敷设方式、接头层布置、电缆支架和夹具等提出了设计要点和要求,为今后国内500 kV电缆敷设设计提供了借鉴作用。
The cable from Sanlin to Jing-an is the first long-distance,large-section 500kV cable line in the country,which was used in Shanghai for the first time.As a 500kV cable,it has special laying requirements.The design points and requirements were proposed aiming at the spread pattern,laying way,joint layer arrangement,cable bracket and fixture of the cable line in the tunnel,which provided the references for domestic 500 kV cable laying design hereafter.
