Low voltage switchboard manufacturer SMB Harwal has received EMR
verification for its iNTELECT G3 switchboards. The company is one of the first manufacturers
in Australia to independently verify its iNTELECT G3 switchboard’s low level of
electro-magnetic radiation emissions (EMR).
Following independent testing of SMB Harwal’s latest generation iNTELECT
G3 switchboard by the NATA-accredited Electrical Testing Company Pty Ltd, the
company has achieved top industry standards and compliance with ARPANSA EMR guidelines
for use in applications such as public and private infrastructure; commercial
and residential apartment buildings; retail, industrial, resources and infrastructure
projects; and mission-critical facilities including energy and industrial
processing facilities, hospitals, health facilities, telecommunications and
financial institution data centres.
The 3rd generation of the widely used iNTELECT system, the iNTELECT G3
system has been engineered in Australia for Australian conditions under strict
quality and environmental standards. The proven iNTELECT switchboards manufactured
in Australia have been reliably serving thousands of data centres, banks,
schools, hospitals, power stations, shopping centres, mines and factories in over
23 countries for over 25 years.
According to SMB Harwal Director Mr Terry Schweickle, the results of
testing both magnetic field and electrical field vindicated the performance of their
advanced, versatile and efficient busbar design with regards to EMR.
For the testing, SMB Harwal specifically selected an existing
installation with the broadest mix of loads that would likely be encountered in
service. Results from the testing established that the EMR levels measured were
well within recommended guidelines; even the strongest magnetic field emissions
from the busbar system did not exceed that of a domestic hairdryer.
SMB Harwal has taken this initiative to raise awareness of EMR as a
design issue, and enable all switchboard users to openly compare the brand’s
EMR performance with the broader market.
Mr Schweickle explains that all busbar systems have EMR emission;
however, EMR emission is minimised in iNTELECT busbars by the symmetrical
busbar arrangement, close proximity of the neutral and earth conductors, and
shielding provided by the modular switchboard housing with its multiple
reliable earthing points.
The testing of the iNTELECT G3 switchboard confirmed readings of up to 30% higher
where the mains and submains cables were taken out of formation to enter or exit
the switchboard at a gland plate.
iNTELECT G3 is the latest new generation of the proven and versatile
iNTELECT modular switchboard range from the SMB Group combining the strength of
custom-built configurations with the flexibility of modular construction.
According to Mr Schweickle, the G3 system integrates SMB Harwal and SMB
Macquarie’s extensive Australian manufacturing and product testing experience,
with valuable customer input accumulated over many years of Australian market
SMB Harwal and SMB Macquarie are part of the international SMB Electric
Switchgear Division under the umbrella of Osaki United International Pte Ltd.
SMB Harwal at Lane Cove and SMB Macquarie at Wetherill Park in
Sydney, specialise in the design, manufacture and testing of custom-engineered
modular constructed low voltage electrical switchboards and motor control
technology, all delivered to short lead times as required. SMB Harwal and SMB
Macquarie have a combined manufacturing area of over 5,000sqm, making them the largest
manufacturer of Australian made LV switchboards in NSW.
