Abstract

Presently Process Industries and Utilities are extensively using XLPE power cables in medium voltage sector for distribution of power. As the current requirements of Process Industries are high and route lengths are in the range 1 to 2 kilometers, Single point bonded system is generally adopted to reduce the overheating of cables. Failures are reported from such bonded medium voltage cables due to improper design and installation. In addition, occurrence of external damage on such medium voltage cables during laying and installation, is also causing failures. Proper analysis of such failures is mandatory to develop better maintenance and installation practices which can avert unexpected failure in the system. Even though it is very difficult to ascertain the failure cause from the failure spot, it is possible to analyze the failure by thorough inspection of the failed piece of cable by dissection and further checking the nearby cables. Here in this paper, a detailed investigation carried out on the failure analysis of a single core 1000 sq.mm medium voltage cable is highlighted.

中压单键电缆系统失效分析

目前，过程工业和公用事业广泛使用交联聚乙烯电力电缆进行中压配电。由于目前过程工业要求较高，线路长度在1 ~ 2公里范围内，一般采用单点键接系统，以减少电缆过热。由于设计和安装不当，此类保税中压电缆出现了故障。此外，这种中压电缆在敷设和安装过程中发生的外部损坏也会造成故障。必须对此类故障进行适当的分析，以制定更好的维护和安装方法，从而避免系统出现意外故障。虽然从故障点确定故障原因是非常困难的，但通过对故障电缆的解剖和进一步检查附近电缆的深入检查，可以分析故障原因。本文对单芯1000sq的失效分析进行了详细的研究。突出显示Mm中压电缆。
