LV panel range successful in latest IEC standard testing
Shaw Controls, a member of the ZestWEG Group, has successfully
concluded a programme of product tests on its low voltage range
of panels at the SABS-NETFA laboratory.Tests were performed in
accordance with the latest IEC protocols, namely IEC 61439-2 Ed
1 / SABS 61439.
“Shaw Controls has recognised a trend in the market whereby
clients are requesting 690 V as their primary voltage, and in that
regard we have taken the initiative of testing our product range at
690 V.The successful tests demonstrate Shaw Controls’ engineer-
ing capability and build quality, which reaffirms our commitment
to the industry,” Bevan Richards, managing director at Shaw
Controls, says.
The latest certification not only gives the company a significant
advantage in the local market, but boosts the capability of the Zest
WEG Group to offer a total solutions approach to its customers.

High pressure waterblast hose ensures operator safety
Power management company Eaton has
launched the new Safeshield EC910 high
pressure waterblast hose for their cus-
tomers in Africa. This engineered hose is
designed to ensure the highest levels of
safety in settings where workers are per-
forming non-polluting industrial cleaning,
stripping and removal of corrosion, paint,
chemical and organic residues.
“With pressures high enough to meet
even the most stringent waterblast appli-
cations, the Safeshield EC910 hose is the
latest in Eaton’s long line of high-quality
waterblast hose assemblies,” said Leonard
Myburgh, product manager, Eaton, Africa.
“This next generation hose is custom de-
signed to perform at five times the industry
impulse cycle life requirement, demon-
strating Eaton’s dedication to reaching the
highest levels of reliability, operator safety
and commitment of building amore energy
efficient Africa.” he added.
Capable of withstanding operating pres-
sures as high as 1 100 bar (16 000 psi),
EC910 meets and exceeds the Internation-
al Organisation for Standardisation (ISO)
7751 requirements. It is constructed with
heavy steel wire reinforcement, featuring
Eaton’s highly abrasion resistant Dura-Tuff
hose cover, providing excellent flexibility,
long service life and ease of handling in
the field. EC910 is available in sizes -08, -12
and -16, approved for working pressures
from 1 100 bar to 690 bar (16 000 psi to
10 000 psi), respectively, with a burst factor
of 2,5 times the normal working pressure.
Eaton’s waterblast hoses are assembled by
professionally trained personnel to ensure
the highest quality available. These hoses
are also available in 15 m (50 foot) and
20 m (66 foot) lengths, with the following
qualified hose fitting styles: male NPTF,
DKO, and BSPP.

Controlled access and high level of cleanliness
LH Marthinusen’s Johannesburg transformer manufacturing and
repair facilities needed to ensure that entrance to their winding
shop was subjected to a controlled access process to guarantee
the highest levels of cleanliness. Based on Apex Strip Curtains &
Doors’ reputation and product offering, LH Marthinusen selected
their SR 9000 heavy duty insulated impact
traffic door. Apex delivered and installed
the two double doors and two single doors
after assessing the optimum solution for the
facilities. “By ensuring that the lowest possi-
ble amounts of dust and other contaminants
enter the section where winding assembly
takes place, we are able to improve trans-
former lifespan. Our existing barriers included
wooden doors, which were unable to ensure
the high levels of cleanliness we required.
One of our larger clients regularly performs
site inspections and the inclusion of superior
quality heavy duty doors formed a focal point of our ongoing im-
provement programme to retain preferred supplier status,” says
Corné Pretorius, electrical planner for large transformers at LH
Marthinusen. Pretorius is particularly pleased with the durability
provided by the bull nosed edge on the perimeter edges of the door.
“The doors are subjected to a fair amount of
knocks and bumps and have to date shown
absolutely no signs of wear.This is an impor-
tant factor, contributing to the reliability and
longevity of the door, which in turn ensures
that the environmental impact on the insulated
winding facility is kept to a minimum over
extended periods of time.” High bumpers are
also fitted to the door panel to further absorb
impact from forklift trucks and carts and reduce
stress on hardware and mount assemblies.
