13.1.5.6 拉線與拉桿的拆除（如有必要）
拉線的恢復(fù)工作僅能在地面上進(jìn)行，屆時配電網(wǎng)的拆除工作已經(jīng)結(jié)束。拉線的拆除應(yīng)通過松開兩邊平行槽的緊固螺絲完成，從而恢復(fù)鋼纜的使用。
13.1.5.7 極的挖掘
務(wù)必圍繞極的底部進(jìn)行挖掘直至其基礎(chǔ)部分可以自由活動，然后小心吊起該極。不得在尚未松開極的基礎(chǔ)部分的情況下將極拔出。如果在拆除后，極仍可以恢復(fù)并可繼續(xù)使用，則必須注意拆除工作以防對極產(chǎn)生任何其他的損傷。
13.1.5.8 服務(wù)連接的拆除（如有必要）
在將現(xiàn)有客戶連接至新的網(wǎng)絡(luò)之前應(yīng)及時通知這些客戶。先將當(dāng)前所有的電氣連接都斷開，然后把地下或高空電纜移開，接下來再進(jìn)行新的高架服務(wù)連接。在對現(xiàn)有客戶服務(wù)連接的地方，無須將接地桿移開。
13.1.5.9 工作順序
一般的工作順序應(yīng)是從MV電壓線開始，然后是配電變壓器，最后才是二次網(wǎng)絡(luò)。承包商應(yīng)注意所有客戶的服務(wù)連接�；旧�，桑尼亞國家電力公司（TANESCO）- 與承包商互相配合-將能夠處理好客戶連接的工作。
遵守區(qū)劃原則，即：先將拆除工作集中在某一各變電站及其相關(guān)電路上，然后再開展下一個電站工作。
承包商將每日報告（以及兩天的預(yù)期內(nèi)容）遞交給雇主以及項目經(jīng)理，指出其即將開展的活動以及開始和完成時間。
13.2 與地下電纜安裝相關(guān)的工作
13.2.1 總則
預(yù)期在達(dá)累斯薩拉姆（Dar es Salaam）安裝一根長13.2km的單核XLPE 33 kV電纜。電纜系統(tǒng)應(yīng)連接至變電站。
•蠔灣（新的及現(xiàn)有的）
•伊拉臘至卡里阿庫
預(yù)計的地下電纜安排，鋪設(shè)深度，所需的電纜空間以及保護(hù)類型都在配電標(biāo)準(zhǔn)圖紙上有所表示。
在合同簽訂前，提供MV地下網(wǎng)絡(luò)的試驗性電纜路線�？墒�，承包商應(yīng)考慮最短的LV地下電纜路徑。
