Real Job — Switchgear Termination
Services
Hands-on electrical expertise across industrial, utility and mining environments.
HV & LV Equipment Maintenance
Unplanned downtime costs you more than any maintenance contract ever will. We run scheduled and corrective maintenance on your high- and low-voltage equipment so small issues get caught before they become site-wide shutdowns.
Transformer Testing & Refurbishment
A failed transformer can take your whole operation offline for days. We test, refurbish and purify oil on your transformers to catch degradation early — extending equipment life and keeping replacement costs off your books for years longer.
Switchgear Installation & Retrofitting
Old switchgear is a liability waiting to happen. We install, retrofit and commission OCB, VCB and ACB units to modern standards — so your protection actually protects, and your compliance sign-off isn't just a formality.
Cable Jointing & Fault Location
Every hour a cable fault goes unfound is an hour of lost production. We pinpoint HT/LT faults fast and carry out jointing and terminations with the precision that keeps a repair from turning into a repeat call-out.
Relay Testing & Protection
Protection relays that haven't been tested are protection relays you can't trust. We run relay testing and secondary injection on systems up to 132kV, so when something does go wrong, your protection actually trips — not your budget.
DB Board Wiring & Fault Finding
A messy, undocumented DB board makes every future fault take twice as long to fix. We build, wire and troubleshoot distribution boards properly the first time — clean, labelled, and built to make the next call-out faster, not harder.
Infrared Scanning
Most electrical failures give off heat long before they give off smoke. Thermal scanning finds the hot joint or overloaded connection weeks before it becomes an outage — the cheapest insurance your site can buy.
Mining & Industrial Sites
Mining and heavy industrial sites don't forgive electrical mistakes. With real underground and surface experience, we work to the standard those environments demand — not the standard a general electrician assumes is good enough.
Our Work
A look at real jobs — from transformer bays to switchgear rooms to site work.
Built on real field experience
Power Pro Electrical is grounded in practical, on-site work across transformers, switchgear, protection relays and distribution systems — not just theory. That experience covers utility-scale equipment, industrial plants and mining operations, both underground and on surface.
- HV/LV maintenance on live industrial sites
- Transformer & switchgear refurbishment and commissioning
- Protection relay testing and secondary injection to 132kV
- Cable fault location, jointing and termination (HT/LT)
- Preventive maintenance, including infrared scanning
Core Skills
Not our first transformer
Anyone can call themselves an electrician. Here's the actual track record behind Power Pro Electrical.
HV Transformer & Switchgear Fieldwork
HV transformer inspections, testing and maintenance; switchgear and minisub station refurbishment; LV panel repairs, DB board wiring, insulation testing; cable jointing, fault location and corrective maintenance on live sites.
Transformer & Motor Maintenance
Maintained and refurbished transformers and switchgear (OCB, VCB, ACB). Relay testing, commissioning, and primary/secondary injection up to 132kV. HT & LT cable terminations, jointing and fault location. Oil purification and infrared scanning.
Substation Servicing & Switchgear Retrofitting
Substation servicing, switchgear retrofitting and testing — the ground-level fieldwork every good electrician's judgement is built on.
That's the difference between a call-out and a fix: someone who has actually stood inside a live switchgear room, under pressure, and gotten it right. That's what you're hiring.
