Why clients keep our number

Safety-led

Work delivered under the OHS Act and applicable electrical regulations, every time.

Technically sound

Practical engineering capability built since 2011 across HV, MV and LV systems.

Asset-focused

Maintenance that protects reliability, performance and long-term asset value.

Responsive

Client-focused support with practical, timely recommendations.

From port terminals to plant rooms to homes, the standard is the same: safe work, done properly, that keeps power on.

Recent field work

A closer look at the kind of work we do, and how we do it.

Technicians maintaining rows of switchgear panels in a substation

Substation switchgear maintenance

Planned maintenance across a full substation: panels opened, breakers racked out, busbars and contacts inspected, insulation checked and every unit returned to service in a known-good state.

Work like this is scheduled around the plant's operating windows so protection is never compromised and downtime stays inside the outage plan.

  • Switchgear inspection
  • Preventive maintenance
  • Condition assessment
Technician servicing a withdrawn circuit breaker

Circuit breaker servicing and refurbishment

Breakers are withdrawn, stripped, cleaned and rebuilt: operating mechanisms serviced, contacts dressed or replaced, lubrication renewed and interlocks verified before the unit goes anywhere near the board again.

Where equipment has aged past economic repair, we advise on retrofit and upgrade options instead of patching problems that will return.

  • Breaker servicing
  • Refurbishment
  • Retrofit solutions
Circuit breakers connected to injection test equipment

Testing, verification and commissioning

Every serviced unit is proven before it carries load: contact resistance, insulation resistance, timing tests and secondary injection of the protection, with results recorded against acceptance criteria.

The same discipline applies to new installations, commissioned methodically so the client switches on with confidence, not hope.

  • Protection relay testing
  • Injection testing
  • Commissioning
Breaker bushings and test instruments laid out in the workshop

Workshop refurbishment

Components that need more than field attention, bushings, mechanisms, contact assemblies, come back to the bench where they can be measured, machined, tested and restored properly.

Bench work gives us controlled conditions and repeatable results, which is exactly what ageing switchgear needs.

  • Component refurbishment
  • Bench testing
  • Spares assessment

On site where the work is

From port terminals and heavy industry to commercial premises and homes, our team works where the equipment lives, under the site's safety regime and around its operations.

Same people, same standard, whatever the address.

  • Industrial sites
  • Commercial premises
  • Domestic work

What clients say

They found a protection fault two other contractors missed, tested everything properly and left us with the reports to prove it.

Plant engineer, industrial client

Breakers were serviced over a single shutdown window and every unit was back in service on time. Clean, safe work throughout.

Maintenance manager, terminal operations

From the quote to the Certificate of Compliance, everything was explained in plain language and done when they said it would be.
