What we do

Five disciplines.
One specialisation.

We don't do general contracting. Every service below lives inside the medium-voltage envelope — which is why the workmanship holds up under mine-spec scrutiny.

SVC / Refurbishment

Switchgear Refurbishment & Repairs

Full strip-down, refurbishment and repair of MV panels and boards — mechanisms, busbars, insulation, interlocks and secondary wiring restored to as-new condition and verified before return to service.

SVC / Retrofit

Breaker Retrofitting

Retrofit of ageing oil and air breakers with modern vacuum technology — extending switchboard life by decades at a fraction of full replacement cost, with protection coordination reviewed as part of the job.

SVC / Testing

Breaker & Panel Testing

Primary and secondary injection, insulation resistance, contact resistance, timing and protection relay testing — with clear, client-ready test reports for compliance and insurance files.

SVC / Maintenance

Minisub & Transformer Maintenance and Repairs

Scheduled and breakdown maintenance of miniature substations and distribution transformers: tap changers, bushings, gaskets, protection devices and enclosures — on site or in our workshop.

SVC / Oil

Transformer Oil Purification

On-site degassing, dehydration and filtration of transformer oil to restore dielectric strength — with before-and-after oil analysis so you can see exactly what changed.

Why Kumba

Built for clients who check the workmanship.

/01

Specialists, not generalists

MV is all we do. That narrow focus means deeper fault-finding, faster turnaround and fewer surprises on your switchboard.

/02

OEM-standard workmanship

Refurbishments and repairs are executed and tested to original manufacturer specification — and documented so you can prove it.

/03

Direct engineering accountability

You deal with the engineers doing the work, not layers of admin. Decisions get made quickly and answers come from the people on the tools.

/04

Safety-first, compliance-ready

Lockout discipline, test documentation and safe working procedures suitable for mine and industrial site access requirements.

/05

Anywhere in South Africa

Based in Fochville, minutes from the West Rand mining belt — and mobilised nationwide for planned work and breakdowns alike.
