Delhi Metro Rail Corporation
has started shifting of major
electrical lines and
transformers to execute construction
work on the 13.875-km long
Badarpur-YMCA (Faridabad)
corridor.
As part of this work, a 220kV and a
66kV Double Circuit transmission
line would be raised for the
construction of viaduct and proposed
NHPC Chowk station. Another 66kV
Double Circuit transmission lines
which is running along proposed
YMCA Station would be converted
into underground by laying about 12
km single core cables. According to a
DMRC release, shifting of electrical
utilities in this metro corridor is a
major challenge for DMRC Engineers
due to the following factors:
- Almost all the 517 piers are affected
and infringing with 2/3 circuits of
overhead 11kV electrical lines and
underground cables.
- Space for shifting of electrical
utilities is not available at number
of locations. The electrical
installations would be shifted after
land is made available for which
HUDA has already been requested.
This is the first time in history of
DMRC that the Electrical lines
infringing through out the corridor at
all Piers and station locations.
DMRC has already started shifting
of 11kV/LT electrical lines including
63 pole/plinth mounted sub stations
adjacent to the entire Faridabad
Metro alignment. These existing
electrical lines are feeding most of the
factories and households of Faridabad
in 10.875 km stretch. Nearly 4 km of
electrical lines including six
transformers of various ratings have
already been shifted in close coordination
with DHBVN without
any inconvenience to consumers.
This is for the first time that such
type of work has been done in Delhi
by raising the height of the lowest
conductor from 8m to a record height
of 34m on 58m narrow base terminal
towers. At another location the
height of a 220kV line double circuit
tower line that was dangerously
passing through congested area of
Lalita Park in East Delhi was raised,
on Vikas Marg.
This fully elevated corridor will
have nine stations and likely to be
operational by year 2014. This is an
extension of already operational
20.16-km long Central Secretariat-
Badarpur corridor of Line-6 which is
further extended from Central
Secretariat to Kashmere Gate
covering 9.36 km.
