13.1.5.6 拉线与拉杆的拆除（如有必要）
拉线的恢复工作仅能在地面上进行，届时配电网的拆除工作已经结束。拉线的拆除应通过松开两边平行槽的紧固螺丝完成，从而恢复钢缆的使用。
13.1.5.7 极的挖掘
务必围绕极的底部进行挖掘直至其基础部分可以自由活动，然后小心吊起该极。不得在尚未松开极的基础部分的情况下将极拔出。如果在拆除后，极仍可以恢复并可继续使用，则必须注意拆除工作以防对极产生任何其他的损伤。
13.1.5.8 服务连接的拆除（如有必要）
在将现有客户连接至新的网络之前应及时通知这些客户。先将当前所有的电气连接都断开，然后把地下或高空电缆移开，接下来再进行新的高架服务连接。在对现有客户服务连接的地方，无须将接地杆移开。
13.1.5.9 工作顺序
一般的工作顺序应是从MV电压线开始，然后是配电变压器，最后才是二次网络。承包商应注意所有客户的服务连接。基本上，桑尼亚国家电力公司（TANESCO）- 与承包商互相配合-将能够处理好客户连接的工作。
遵守区划原则，即：先将拆除工作集中在某一各变电站及其相关电路上，然后再开展下一个电站工作。
承包商将每日报告（以及两天的预期内容）递交给雇主以及项目经理，指出其即将开展的活动以及开始和完成时间。
13.2 与地下电缆安装相关的工作
13.2.1 总则
预期在达累斯萨拉姆（Dar es Salaam）安装一根长13.2km的单核XLPE 33 kV电缆。电缆系统应连接至变电站。
•蚝湾（新的及现有的）
•伊拉腊至卡里阿库
预计的地下电缆安排，铺设深度，所需的电缆空间以及保护类型都在配电标准图纸上有所表示。
在合同签订前，提供MV地下网络的试验性电缆路线。可是，承包商应考虑最短的LV地下电缆路径。
