13.1.5.6 拉線與拉桿的拆除（如有必要）
拉線的恢復工作僅能在地面上進行，屆時配電網的拆除工作已經結束。拉線的拆除應通過松開兩邊平行槽的緊固螺絲完成，從而恢復鋼纜的使用。
13.1.5.7 極的挖掘
務必圍繞極的底部進行挖掘直至其基礎部分可以自由活動，然后小心吊起該極。不得在尚未松開極的基礎部分的情況下將極拔出。如果在拆除后，極仍可以恢復并可繼續使用，則必須注意拆除工作以防對極產生任何其他的損傷。
13.1.5.8 服務連接的拆除（如有必要）
在將現有客戶連接至新的網絡之前應及時通知這些客戶。先將當前所有的電氣連接都斷開，然后把地下或高空電纜移開，接下來再進行新的高架服務連接。在對現有客戶服務連接的地方，無須將接地桿移開。
13.1.5.9 工作順序
一般的工作順序應是從MV電壓線開始，然后是配電變壓器，最后才是二次網絡。承包商應注意所有客戶的服務連接。基本上，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。
遵守區劃原則，即：先將拆除工作集中在某一各變電站及其相關電路上，然后再開展下一個電站工作。
承包商將每日報告（以及兩天的預期內容）遞交給雇主以及項目經理，指出其即將開展的活動以及開始和完成時間。

• 連接端和電纜封頭的供應，以及為工廠通電。
• 要求可行的設計和制造方案，沿電纜路徑的混凝土管坑應帶有蓋子。
• 各種必備材料的備品，例如：例如軟焊材料、苯、丙烷、乙炔，氧空氣以及汽油，從而使得工程滿足項目經理的要求。
13.2.2 電纜安裝
13.2.2.1 總則
電纜及其附件的安裝，測試，試運行應由承包商的人員完成，當地的技術和非技術工人應在有承包商人員監督的情況下進行挖掘、電纜鋪設，回填以及土木工程等工作。
本合同中，承包商應雇傭合格的且有經驗的員工，這些員工應有相關安裝工作的經驗。現場至少有一名監理人員和多位測試及試運行工程師。
在未得到項目經理書面批準的前提下，不得進行電纜的鋪設，挖掘，回填操作或施工等工作。
變電站的土木工程施工應符合第七部分，總的技術規范。在變電站內，將電纜鋪設于混凝土電纜溝中，使MV饋電線伸出。
電纜應沿路徑鋪設，鋪設位置應事先得到批準。在為了必須避開障礙物，或者為了配合城鎮規劃機構及其他部門進行調配的情況下，項目經理有權更改電纜路徑和位置。

13.1.5.6  Dismantling of Guys, Stays (if any)
Guys shall be recovered from above ground only and shall be done when distribution network disman¬tling is completed. Guy dismantling shall be carried-out by loosening on both sides the parallel-groove clamp bolts in order to recover steel cable.
It shall be necessary to excavate around pole bases until foundations are free, then with care the pole shall be lifted. In no case the pole shall be pulled-out without freeing the foundation. If a pole is recov¬erable for subsequent re-use after dismantling it shall be carefully handled to avoid additional damage.
13.1.5.8  Dismantling of Service Connections (if any)
Existing customers shall be notified before proceeding to connect them to new network. All electrical connections of present supply shall be disconnected, then underground or aerial cable at the meter shall be removed, to be subsequently connected to the new overhead service connection. The earthing rod shall not be removed where installed on existing customer's service connection.
13.1.5.9  Sequence of Works
In general the sequence shall begin with MV voltage lines, then distribution transformers and subse¬quently the secondary network. The Contractor shall pay special attention to the service connections of all customers. Basically, TANESCO - in coordination with the Contractor - will handle the customer connections. :
The zone principle shall be followed; i.e., dismantling shall be focused on each substation and its as¬sociated circuits, before progressing to the next substation.
The Contractor shall submit a daily report (with two days anticipation) to Employer and Project Man¬ager indicating activities to be performed and time of commencement and completion.
13.2  Works Associated with Underground Cable Installations 13.2.1 General
it is expected to install nearly 13.2 km of single-core XLPE 33 kV cable in Dar es Salaam. The cable system shall connect the Substations
• Oysterbay (new and existing),
• Mala to Kariakoo.
The proposed arrangements of the underground cables, the laying depth, the necessary cable spac¬ing, and the type of protection are shown on the drawings in the distribution standards.
The tentative cable routes for the MV underground networks will be provided prior to contract award. However, the Contractor shall consider the shortest way for the LV underground cable routes.
