5、压电缆敷设施工。Project name: TDI Train Plant Medium Voltage Cable Pulling Work.本工程涉及三个变电站，分别是现有的220/35kV A472变电站、现有的35/10kV B301S变电站以及新建的35/10kV C581变电站，工作内容为三个变电站之间和从三个变电站接至MV用户的电力电缆、控制电缆、接地电缆的敷设。The project involves three substations, namely the existing 220/35kV A472 substation, the existing 35/10kV B30
6、1S the 35/10kV C581 substation and a new substation. This is the power, control and grounding cable pulling among three substations and for MV users connected to the three substations.1.2 施工范围 Scope of Work1) A472建筑（220/35kV变电站）出线回路：A472 Building(220/35kV substation) outlet circuit由A472变电站引出3路35kV出线
7、。其中：一路引至B301S建筑（35/10kV变电站）原1#主变，原1#主变电缆将抽出，与新增4#主变连接；另两路引至35/10kV C581变电站1#主变和2#主变。回路采用FS-YJY-26/35kV-1*300mm2单芯电缆，直埋敷设。去C581的两路35kV线路，敷设时沿不同路径，以避免两回线路同时受损。Pull three 35V outgoings from A472 substation. Of which: The first outgoing is led to B301S Building (35/10kV substation) the original one # ma
8、in transformer, pull the original one # main transformer cable out, and connect to the adding 4 # main transformer; the other two outgoings are led to 35/10kV C581 # 1 and substation 2 # main transformer. Use FS-YJY-26/35kV-1 * 300mm2 single-core cables for Loop and buried pulling. Two 35kV lines to
9、 C581 are laid along different paths to avoid damage of the two loops.2) B301S建筑（35/10kV变电站）出线回路：B301S building (35/10kV substation) outlet circuit:由B301S变电站引出7路10kV出线。全部引至B399中心制冷站。回路采用10kV截面为95mm2的三芯铠装电缆，由B301S南面现有的电缆井引出直埋至装置。Pull 7 10kV outgoings from B301S substation to B399central refrigeration
10、 station. Loop uses 10kV three-core armored cable with cross-section 95mm2 and pull out from the existing cable well in the south of B301S then buried lay to the device. 3) C581建筑（35/10kV变电站）出线回路：C581 building (35/10kV substation) outlet circuit:由C581引出10路10kV线路，分别为A507的四台变压器，B551的两台变压器，B553TDA装置氢气压
