Switchgear

Switchgear is electrical equipment used to control, protect and isolate electrical circuits and equipment in power generation, transmission and distribution systems. It combines switches, fuses, circuit breakers and other protective devices in a single enclosure to safely manage electrical power flows and disconnect circuits during maintenance or fault conditions. Switchgear is classified by voltage level, with low-voltage units serving systems up to 1 000 V, medium-voltage equipment handling 1 kV to 36 kV, and high-voltage switchgear operating above 36 kV. The equipment plays a critical role in substations, industrial plants, data centres, mining operations and commercial buildings, where it ensures continuity of supply and protects personnel and assets from electrical faults. Modern switchgear increasingly incorporates digital monitoring and control technologies, including supervisory control and data acquisition (SCADA) integration and condition-monitoring sensors that track performance and predict maintenance needs. Manufacturers produce both air-insulated and gas-insulated variants, with the latter offering compact footprints for space-constrained installations. The global switchgear market is driven by grid modernisation, renewable energy integration and the expansion of industrial and data-centre infrastructure. Major producers include Siemens, ABB, Schneider Electric and regional specialists such as South Africa's ACTOM. Switchgear design has evolved from electromechanical relays to solid-state and microprocessor-based protection systems, improving reliability and enabling remote operation.

Trafo Power Solutions widens focus ahead of Electra Mining Africa 2026

Trafo Power Solutions, present at Electra Mining Africa since 2017, has evolved from a dry-type transformer supplier into a provider of integrated power solutions, including mini substations, mobile substations, containerised power solutions, switchgear and engineered electrical distribution systems for mining, industrial and infrastructure customers. Managing director David Claassen says mines increasingly want engineered, fit-for-purpose systems addressing total power reliability in harsh African conditions rather than standalone equipment, and the company will showcase its technical capabilities at the 2026 exhibition.

Schneider Electric links SF₆-free switchgear to digital intelligence for mines

Schneider Electric positions its SF₆-free AirSeT switchgear range, which replaces sulphur hexafluoride (global warming potential 25 200 times that of carbon dioxide) with pure air, as a tool for decarbonisation and operational resilience. Under South Africa's Carbon Tax Framework, mines using SF₆ risk penalties from leaks, while embedded condition monitoring, arc-flash optical sensors and predictive analytics through EcoCare 24/7 can cut maintenance needs by up to 40%.

Local manufacturers emphasise resilience and product authenticity

ACTOM MV Switchgear develops SF₆-free solid dielectric insulated switchgear extending up to 40.5 kV, backed by 24-hour support, while Hansen + Genwest, marking 50 years of operation, supplies dry-type transformers and switchgear for underground and flameproof mining applications. Claassen has separately warned buyers to verify mini-substation authenticity, requesting factory acceptance test reports and quality documentation to guard against cosmetically restored units sold as new.
