New range innovative switchgear
Schneider Electric, a global specialist in en-
ergy management and automation, builds
on innovation and experience for its 40,5
kV gas-insulated switchgear (GIS) offer.The
cutting-edge GHA is now available to the
Southern Africa market and beyond.
This new range of convenient and in-
novative switchgear incorporates a user-
friendly operator interface, sealed-for-life
medium voltage compartments and intel-
ligent gas monitoring – helping to decrease
facility switchgear total cost of ownership,
streamline operations, reduce mainte-
nance, and enhance safety and reliability.
Today’s facilities and plants, constrained
by limited space requirements, are looking
for smaller equipment that neither compro-
mises on safety nor performance. “Schnei-
der Electric’s GIS delivers a compact design
combined with easy-to-install features that
provide drastic space savings, as compared
to traditional primary metal enclosed air-
insulated- and gas insulated switchgear,”
highlights Brighton Mwarehwa, technical
manager for southern Africa at Schneider
Electric.
Reliable and safe switchgear is funda-
mental for optimising equipment perfor-
mance and plant operations, and Schneider
Electric’s GIS solution features internal
arc-resistant designs that have been tested
and passed as per IEC and IEEE standards
requirements, which help mitigate effects
of faults and provide high level of worker
safety.
The GHA is tested for internal arc faults,
up to 40 kA for one second. “The progres-
sive technology by Schneider Electric now
delivers even more power at the reduced
dimensions. Options for single or double
busbars are offered and up to a busbar
rating of 4 000 A is available for the single
busbar option,” adds Mwarehwa.

Extended product guarantees
Long gone are the days of being considered a run-of-the-mill OEM. This is the
strong message being given to all industries by Zest WEG Group Africa. With
WEG Brazil as its parent company, this group has its roots firmly in Africa and
its commitment to the continent is without question, especially following the
large investments made in 2015 in local manufacturing facilities that will be able
to service countries across Africa.
Such is the confidence and level of commitment of ZestWEG Group Africa to
its customer base that Louis Meiring, group Chief Executive Officer, announced
guarantees have been extended across all WEG products.
“Zest WEG Group Africa is known for leading industry in its thinking and the
decision to extend the product guarantees is, we believe, another very important
first,” Meiring says. “While the extended guarantee will cover customers for
unexpected electrical and/or mechanical failures giving them absolute peace of
mind, it is not going to cost them more.”
Meiring says that this was a prime consideration for ZestWEG GroupAfrica as
the organisation is well aware of the additional financial pressures that many of
its customers are operating under in the current financial climate. “By extending
our product guarantees we are increasing the peace of mind that customers have
with WEG products and opening the door for potential customers to examine
what we know is an unbelievable value proposition.”
Extended guarantees will vary from product to product, but all customers
are still assured of the same high level of in-field support for which Zest WEG
Group Africa is known.

Seminar on lightning
protection
In response to massive industry interest, DEHN AF-
RICA the local subsidiary of Germany-based DEHN
+ SÖHNE, recently ran a two-day seminar that of-
fered attendees a fully comprehensive approach to
lightning protection. The course was endorsed by
the South African Institute of Electrical Engineers
(SAIEE), which approved two CPD credits. Delivered
by Alexis Barwise, managing director of DEHN AF-
RICA, the seminar covered:
• The characteristics of lightning, how it is formed
and the types of flashes that exist; along with
the types of risks and damage associated with a
lightning strike
• How to assess the risks associated to a structure/
building/plant and to apply mitigation methods
in order to protect personnel, the structure and
its equipment
• Designing a compliant and effective lightning
protection system (LPS) including all the ele-
ments of an LPS (air-termination systems,
down-conductors, earth-termination system,
separation distance and equipotential bonding)
• Selecting compliant lightning and surge protec-
tion devices through understanding the full re-
quirements of these devices and other applicable
standards; along with the certification of an LPS
using the SANS installation safety report
