Preventing Loose LT Lines:
If the LT lines are extremely loose or they sag, shorting of LT lines could occur and cause frequent blowing of feeder fuses. It could also cause conductor snapping if proper size of fuses are not used or if the structure is not properly earthed. To avoid this from happening, phase separators should be used or lines should be restaged. Loose LT lines should be checked to decrease short circuit stresses on transformer and therefore enhance its life.
