According to the analysis of the cause of the outer sheath, it can be seen that the cable line project is a systematic project, only from the design, construction, operation, and maintenance aspects of its entire process management, in order to maximize its safe operation.
1 From the beginning of the design, the cable was used to fully understand the grounding system, and select the line in line with its voltage level, to avoid the cable in the case of long-term over-voltage work.
The selection of the outer sheath should be in accordance with the requirements of the environment, and service life and the cable sheath protector should be selected to meet the relative ground, the protector reliable through the ground current without damage to the principle.
2 To strengthen the cable project in all aspects of the hidden engineering and intermediate links acceptance, strict quality acceptance, the civil engineering, electrical and other engineering acceptance found defects, hidden risks to complete rectification, and make the record, if necessary, leave photos, Film, and television and other information.
3 The use of external jacket online monitoring technology, online optical fiber temperature measurement technology, and online partial discharge detection technology.
And another advanced online monitoring technology enhances the real-time monitoring of the cable line, and early detection of hidden defects, to avoid the occurrence of power outages.
