浅谈直埋光缆金属护套对地绝缘不良的查找

Brief Introduction of Fault Location of Mal-insulation from the Earth of Direct Burial Optical Cables with Metal Sheath

施工结果表明：同沟敷设与另行直埋通信光缆相比，可节省40%的资金，施工质量达到了设计要求。

It shows that 40 % costs could be saved by one ditch method comparing with separate laying method .

通过对直埋电缆、光缆对地绝缘电阻、对碳钢、黄铜、铅、铝的腐蚀率及土壤环境因素的原位连续测试，研究电缆、光缆及金属护套材料的土壤腐蚀规律。

Based on the in situ measurement of insulation resistance against ground of buried cable and optical cable , corrosion rate of carbon steel , brass , lead and aluminium , as well as soil environmental factors , regularities of soil corrosion have been investigated .
