The 4 predominant causes of HV cable failures


Each time human behaviour is concerned, issues get fascinating! Failures from exterior mechanical injury akin to throughout excavations are a critical concern. If an excavator hits a cable, then the insulation will break down as a result of mechanical injury. One other much less seemingly reason behind failure because of mechanical stress is putting in cables and exceeding the minimal bending radius of the cables. What’s not stunning is excavation failures are a lot much less more likely to happen when it’s not a workday (weekend) or when it’s lunchtime (12pm).

Very apparently the report discovered that excavation-caused failures are 8% increased than anticipated on non-rainy days and 21% decrease than anticipated on wet days. Evidently employees are way more cautious throughout instances when the climate situations are poor.
