Among them, transformer circuit uses x 3core armored cable with 10kV crosssection 185mm2, motor circuit uses threecore armored cable with 10kV crosssection 95mm2. All cable lines will be laid underground along the planning path.4) 接地電纜回路：Ground cable loop: 從 A472 敷設一根 95mm2 裸銅線去 C581，同時從 C581 敷設四根 95mm2 裸銅線，分別引至B55 A50B553 和 C521，作等電位聯(lián)結。以上電纜線路均沿規(guī)劃路徑埋地敷設。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 4 / 145) 控制電纜回路： Control cable circuit:安裝在 HCL 裝置現(xiàn)場的 馬達上的電流信號通過一根直埋敷設的鎧裝控制電纜直接接入10KV 開關柜。The current signal installed on motor in the HCL devices site passes through a buried armored control cable direct access to 10KV switchgear.由變壓器出線柜去 C581 以外的變壓器，采用兩根分別為 10*、4* 2 屏蔽鎧裝控制電纜，由中壓轉(zhuǎn)接柜引出，與中壓電纜同路徑敷設至相關變壓器室。其中，10* 電纜直接接至溫控箱，4* 電纜可集中從某間變壓器室引出，沿橋架至相關 PCS 樓 ATS 柜。Transformer outlet cabis are connected to other transformers not in C581 by using two 10 * , 4 * shield sheathed control cable respectively.
