SMB Harwal Electric has become one of the first manufacturers in Australia to independently verify its iNTELECT G3 switchboard’s low level of electro-magnetic radiation emissions (EMR).

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.

Tens of thousands of iNTELECT switchboards manufactured in Australia have been giving reliable service for over 25 years in data centres, banks, schools, hospitals, power stations, shopping centres, mines and factories in over 23 countries.

The low voltage switchboard manufacturer’s latest generation iNTELECT G3 switchboard was subjected to independent testing by the NATA-accredited Electrical Testing Company Pty Ltd to ensure it 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.

SMB Harwal Director Mr Terry Schweickle observes that the results of testing both magnetic field and electrical field parameters vindicated the performance of their advanced, versatile and efficient busbar design with regards to EMR. For the testing, SMB Harwal specifically picked an existing installation with the broadest mix of loads that would likely be encountered in service. Testing results revealed that the EMR levels measured were well within recommended guidelines.

SMB Harwal Electric has decided to take this industry-leading initiative to raise awareness of EMR as a design issue, and to ensure all users of switchboards could openly compare SMB’s EMR performance with the broader market.

He explains that all busbar systems emit EMR, but the iNTELECT busbar’s 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 minimise EMR.

Mr Schweickle adds that 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 leadership.

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 Australian design, manufacture and testing of custom-engineered modular constructed low voltage electrical switchboards and motor control technology. Their combined manufacturing facilities of over 5,000sqm make them the largest manufacturer of Australian made LV switchboards in NSW.
