REFURBISHMENTS
New low noise transformers were
installed and at the same time the
outdoor switchgear was brought
indoors which also makes the site
look cleaner and tidier.The replaced
transformers will be refurbished and
utilised as critical spares.
At our Peacockes Road Substation
the 33kV outdoor lattice steel
structure, oil-filled circuit breakers
and air-break switches were nearing
the end of their economic life.
The age of the switchgear, coupled
with regional growth and winter
demand meant we needed to upgrade
to new gas insulated switchgear, and
this was part of a broader plan to
upgrade the entire substation.
The transformers have also been
replaced and further refurbishments
are planned for this coming year.
Noise from older infrastructure was an issue at
our Wallace Road substation, so we decided to
replace the two existing transformers.
NETWORK
REINFORCEMENT
Our Tasman Road substation
had been identified as having
a shortfall of transfer capacity
during a full 33kV/11kV
transformer outage. A new
11kV cable was installed
between Tasman and Pukete
substations and this was
successfully commissioned
in March 2015.
