【正文】 裸銅線，分別引至B55 A50B553 和 C521，作等電位聯(lián)結(jié)。以上電纜線路均沿規(guī)劃路徑埋地敷設(shè)。Pull 7 10kV outgoings from B301S substation to B399central refrigeration station. Loop uses 10kV threecore armored cable with crosssection 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 變電站）出線回路：C581 building (35/10kV substation) outlet circuit:由 C581 引出 10 路 10kV 線路，分別為 A507 的四臺(tái)變壓器，B551 的兩臺(tái)變壓器，B553TDA 裝置氫氣壓縮機(jī) 2 臺(tái)，C521 鹽酸裝置氯氣壓縮機(jī) 1 臺(tái)，鹽酸壓縮機(jī) 1 臺(tái)提供電源。全部引至 B399 中心制冷站。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?；芈凡捎?FSYJY26/35kV1*300mm2 單芯電纜，直埋敷設(shè)。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. 施工范圍 Scope of Work1) A472 建筑（220/35kV 變電站）出線回路：A472 Building(220/35kV substation) outlet circuit由 A472 變電站引出 3 路 35kV 出線。1 / 14TDI train Infrastructure Electrical System InstallationMV Cable Pulling Construction PlanTDI 聯(lián)合裝置基礎(chǔ)設(shè)施電氣系統(tǒng)安裝　中壓電纜敷設(shè)施工方案 B 11/30/2022 ISSUED FOR COMMENTSA 11/26/2022 ISSUED FOR COMMENTSRev DateDD/MM/YY STATUS PREPARED BY CHECKED BY APPROVED BYDOCUMENT REVISIONS目 錄Content2 / 14一. 概況 OVERVIEW............................................................................................................................................3 工程概況 PROJECT OVERVIEW ..............................................................................................................3 施工范圍 SCOPE OF WORK.......................................................................................................................3二．編制依據(jù) COMPILATION BASIS .................................................................................................................4三． 施工工藝流程：CONSTRUCTION PROCESS ...........................................................................................4四. 前期準(zhǔn)備 PREPARATION .............................................................................................................................4 技術(shù)準(zhǔn)備 TECHNICAL PREPARATION ..................................................................................................4 材料準(zhǔn)備 MATERIAL PREPARATION .......................................................................................................5 主要機(jī)具準(zhǔn)備 MAIN EQUIPMENT PREPARATION ...............................................................................5 作業(yè)環(huán)境準(zhǔn)備 WORK ENVIRONMENT PREPARATION .......................................................................6五. 敷設(shè)施工 WORK OF CABLE PULLING.....................................................................................................6 電纜敷設(shè)施工工序 WORK PROCEDURE ..................................................................................................6 機(jī)具布置 LAYOUT OF TOOLS ..................................................................................................................6 電纜的搬運(yùn)及支架架設(shè) CABLE REMOVAL AND CABLE TRAY ..........................................................6 卷揚(yáng)機(jī)與滑輪的布置 WINCH AND PULLEY ARRANGEMENT .........................................................6 電纜展放 LAYOFF CABLE .......................................................................................................................10 電纜敷設(shè)、固定 CABLE LAYING AND FIXING....................................................................................12六. 覆砂蓋磚 SPREAD SAND AND COVER BRICKS ....................................................................................12七. 回填土 BACKFILL EARTH .........................................................................................................................13八. 埋標(biāo)樁 BURYING STAKE ............................................................................................................................13九. 掛標(biāo)志牌 HANGING SIGNS.........................................................................................................................13十. 質(zhì)量控制 QUALITY CONTROL..................................................................................................................13 主控項(xiàng)目 MASTER ITEMS.......................................................................................................................13 一般項(xiàng)目 GENERAL ITEMS....................................................................................................................14十一. 成品保護(hù) FINISHED PROTECTION ........................................................................................................14十二. 質(zhì)量記錄 QUALITY RECORD....................................
