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 B301S 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 施工范围施工范围 Scope of Work 1) A472 建筑（建筑（220/35kV 变电站）出线回路：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。

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 # main 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 C581 are laid along different paths to avoid damage of the two loops. 2) B301S 建筑（建筑（35/10kV 变电站）出线回路：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 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（建筑（35/10kV 变电站）出线回路：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 置氢气压缩机 2 台，C521 盐酸装置氯气压缩机 1 台，盐酸压缩机 1 台提供电源。

其中，变压器 回路采用 10kV 截面为 185mm2的三芯铠装电缆，马达回路采用 10kV 截面为 95mm2的三芯铠装 电缆以上电缆线路均沿规划路径埋地敷设10 10kV lines led from C581 are used to supply power to A507s four transformers, B551 two transformers, B553TDA 2 sets of hydrogen compressor unit, C521 hydrochloric acid chlorine gas compressor unit, and hydrochloric acid compressor unit respectively. Among them, transformer circuit uses x 3-core armored cable with 10kV cross-section 185mm2, motor circuit uses three-core armored cable with 10kV cross-section 95mm2. All cable lines will be laid underground along the planning path. 4 / 15 4) 接地电缆回路：接地电缆回路：Ground cable loop: 从 A472 敷设一根 95mm2裸铜线去 C581，同时从 C581 敷设四根 95mm2裸铜线，分别引至 B551、A507、B553 和 C521，作等电位联结。

以上电缆线路均沿规划路径埋地敷设Lay a 95mm2 bare copper wire to C581 from A472. Meanwhile lay four bare copper wires to B551, A507, B553 and C521 for equipotential bonding. All cable lines will be laid underground along the planning path. Overview 5) 控制电缆回路：控制电缆回路： Control cable circuit: 安装在 HCL 装置现场的 3.6MW 马达上的电流信号通过一根直埋敷设的铠装控制电缆直接接入 10KV 开关柜The current signal installed on 3.6MW motor in the HCL devices site passes through a buried armored control cable direct access to 10KV switchgear. 由变压器出线柜去 C581 以外的变压器，采用两根分别为 10*2.5mm2、4*2.5mm2屏蔽铠装控制电 缆，由中压转接柜引出，与中压电缆同路径敷设至相关变压器室。

其中，10*2.5mm2 电缆直接 接至温控箱，4*2.5mm2 电缆可集中从某间变压器室引出，沿桥架至相关 PCS 楼 ATS 柜 Transformer outlet cabinets are connected to other transformers not in C581 by using two 10 * 2.5mm2, 4 * 2.5mm2 shield sheathed control cable respectively. The 10 * 2.5mm2 cable directly is connected t。
