A leading Australian electrical company has found a solution that delivers Standards-compliant, safe and portable switchrooms to sites for its major projects across the country.

The electrical project specialist worked with Modulate Group to create a fully sealed containerised switchroom that can easily be moved from site to site, as required. The customised switchroom houses a motor control centre, variable speed drive, distribution board, transformer, local control station, fire indication panel and remote switching panel.

Modulate manufactures customised containerised buildings at its 20,000m² production facility in Mayfield, near Newcastle, NSW, where production and customisation to different needs are handled in-house.

“Electrical switchrooms are some of the more complex containerised buildings we manufacture. We make sure they meet strict AS 3000 Standards, other relevant safety Standards and any client-specific requirements,” Modulate general manager Jack Adams says.

“The customer placed a high importance on safety and quality from the start, and they were clear with their requirements. Not only did they want to meet all relevant Standards, but they wanted to maximise internal space, which is an area where Modulate sets itself apart from other portable offices.”

The electrical switchroom was fully sealed to keep out dust and moisture and could be temperature controlled through three air conditioning units integrated into the roof to save internal space.

“Two units will be operating, and the third is a backup in case one of the others fails. The system will be set up to maintain an overall temperature of below 25°C, with a calculated heat load of 20.432kW,” Jack explains.‌

Modulate containerised buildings, configured from standard approximately 6m, 9m and 12m container templates, are cyclone-rated structures with a design life of 25 years under heavy use, with low maintenance.
