 Replacement of Rusted cantilevers:

Rusted cantilevers are the one of the causes for breakdowns in polluted areas.
Due to the rusting of the rusting of the cantilever tubes, the mechanical
strength of the cantilever will decreases drastically and leads to breakdown of
OHE. To avert the failures due to rusting of cantilevers, replacement work has
taken up and replaced 911 No’s in pollution prone areas.
