(1)不要长时间过负荷运行或过热。因此，不要忽视电缆负荷电流及外度温度、接头温度的监测；

(1) do not overload or overheat for a long time. Therefore, do not neglect the monitoring of the cable load current, the external temperature and the joint temperature.

(2)电缆线路馈线保护不应投入重合闸。电缆线路的故障多为永久性故障，若重合闸动作，则必然会扩大事故，威胁电网的稳定运行；

(2) the feeder protection of the cable line should not be put into reclosing. The fault of cable line is mostly permanent fault. If reclosing, it will inevitably expand the accident and threaten the stable operation of the power grid.

(3)电缆线路的馈线跳闸后，不要忽视电缆的检查。重点检查电缆路径有无挖掘、电线有无损伤，必要时应通过试验进一步检查判断；

(3) when the feeder line of the cable line is tripped, do not neglect the inspection of the cable. The key inspection cable path is not excavated, the wire is damaged or not, if necessary, the test should be examined and judged further through the test.

(4)直埋电缆运行检查时要特别注意：电缆路径附近地面不能随便挖掘；电缆路径附近地面不准缩放重物、腐蚀性物质、临时建筑；电缆路径标志桩和保护设施不能随便移动、拆除。

(4) special attention should be paid to the operation of directly buried cables: the ground near the cable path cannot be excavated; the ground near the cable path is not allowed to scale heavy objects, corrosive substances and temporary buildings; cable path markers, piles and protective facilities cannot be moved or dismantled at will.
