Not one size fits all
As transformers age due to power surges,
over-demand or simply having grown too
small for the capacity required, the problem
of finding a suitable replacement that
can deliver a higher capacity and is better
protected yet has to fit into the same space
of the old transformer, does not have an off-
the-shelf solution. “It is here where our more
than ten years of design and manufacturing
experience comes to the fore. Our engineers
can, in most cases, design a transformer
using the latest technology that will fit into
the available space, yet meet increased
delivery capacity using the same space as
the old transformer. Designs can be adapted
to facilitate assembling the transformer
on site in instances where access to the
substation or the medium voltage substation
is restricted.

Meeting the solar challenges
With the new regulation of allowing systems
of up to a hundred megawatt to be built
by independent power producers, many of
these plants will be using string inverters
to convert the DC output from an array of
panels to AC, requiring medium voltage
substations with low maintenance, high-
capacity output transformers. “Our Armcoil
design team offers innovative solutions to
meet both the electrical as well the physical
specifications”, Bosch said.
ArmCoil is an ISO accredited
manufacturing, repair and on-site
maintenance facility located west of
Johannesburg, in the industrial area of
Roodepoort. The Armcoil facility boasts
a fully equipped factory for transformer,
miniature and MV substation manufacturing
- from design stage to testing, delivery
and installation. ArmCoil holds three
ISO accreditations, namely 9001:2015,
