When your site depends on high voltage infrastructure, you need a high voltage electrical contractor who can keep it running safely and without unplanned downtime. Amped Specialist Electrical is a licensed high voltage electrical contractor based in Maryborough, working across Queensland on switching, maintenance, testing, high voltage commissioning and switchboard projects for industrial sites, substations and solar farms. Our HV technicians hold the training and accreditation needed to work on primary and secondary plant, and every job is backed by detailed reporting so your team always knows the condition of your assets.
From one-off fault response to ongoing maintenance contracts, we work as an extension of your team, not a one-time call-out. That means fewer mobilisation delays, a switching program that’s coordinated around your operations, and a single point of contact who already knows your site.
Why Queensland Businesses Choose Amped as Their High Voltage Electrical Contractor
Amped is a specialist high voltage electrical contractor, not a general electrician offering HV as a side service. Our technicians are trained specifically in high voltage switching, protection systems and industrial power infrastructure, and we hold the licensing required to work safely across factories, substations and renewable energy sites throughout Queensland.
High Voltage Services
HV Switching and Coordination
Our switching operators isolate and make safe for planned shutdowns or urgent faults, coordinating your switching program to minimise downtime, labour hours and overall cost.
High Voltage Commissioning
From new installations to plant upgrades, our high voltage commissioning process confirms every asset is correctly installed, configured and safe to energise before it’s handed over. This covers pre-commissioning checks, functional testing, protection relay verification and final sign-off documentation, so new equipment goes into service without surprises down the line.
Primary Maintenance
Transformer oil sampling, thermal scanning and partial discharge testing, with detailed trend reporting so shutdowns can be scheduled before a fault forces one.
Secondary Maintenance
Relay and control system maintenance, backups of control software, and protection testing to confirm your relays will trip correctly when it matters.
Site and Factory Acceptance Testing
Third-party SAT and FAT testing confirms equipment arrives undamaged and matches specification, catching issues before commissioning rather than after.
HV Cable Testing and Fault Location
Cable testing to Australian standards, plus precise underground fault location so excavation is limited to the exact section that needs repair.
Switchboard Design, Build and Maintenance
In-house design, manufacture and on-site modification of industrial switchboards, engineered to relevant standards and built around your load and protection requirements.
