Overhauls and Maintenance

We conduct two pre-overhaul inspections of flameproof enclosures at different stages to understand the level of deterioration of the explosion protection properties of the enclosure. This can be used as a guide to determine the continued operation of the Exd enclosure as per AS/NZS 2290.1 or if an overhaul is required.   

The level of maintenance performed on a substation depends on a number of factors, including type, age, and assets used in the electrical equipment. Some of the common maintenance activities include visual inspections, testing and diagnostics, cleaning, tightening and torque checks, oil and gas monitoring, and protection equipment maintenance and calibration.  

We perform overhauls in our certified AS/NZS 3800 workshops in New South Wales and Queensland. These facilities are purpose-built for the repair, overhaul and modification of flameproof equipment designed for use in explosive atmospheres. In some cases, we do have the capacity to perform overhauls on site, but this is dependent upon the work required. 

Our workshops are certified under australian standards to support the safe and high-level design, construction, testing and certification of electrical equipment that has been manufactured for potentially explosive atmospheres or hazardous areas.  

An Exd enclosure is a robust, flameproof enclosure that can withstand and contain potential internal explosions, protecting electrical systems and site environments from a hazardous event.
