The 4 most important causes of HV cable failures

At any time when human behaviour is concerned, issues get fascinating! Failures from exterior mechanical harm akin to throughout excavations are a severe difficulty. If an excavator hits a cable, then the insulation will break down as a result of mechanical harm. One other much less doubtless reason for failure resulting from 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 prone to happen when it’s not a workday (weekend) or when it’s lunchtime (12pm).

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