South African manufacturer of specialised electromechanical equipment, Hexagon Electrical, is a leading provider of customised solutions to the mining, utilities, industrial and renewable energy sectors.
Maintaining high voltage-equipment – safety and performance are priorities for Hexagon Electrical.
Hexagon operates from over 6 000 m² of manufacturing space in Brakpan, Gauteng, where its in-house engineering, fabrication, assembly and testing facilities enable it to deliver customised systems across a broad product portfolio.
“At Hexagon Electrical we have the ability to design and manufacture bespoke motors, transformers, panels, flameproof apparatus and ventilation equipment. This gives us a distinct competitive advantage to meet specific project requirements, unique operating conditions and strict safety regulations,” says David Dyce, CEO.
“Every mine, substation and industrial plant has its own operating conditions and constraints, which is why customisation is so important. All products from Hexagon Electrical are developed to address requirements that conventional off-the-shelf systems cannot meet. We are committed to ensuring our products perform optimally and align with each customer’s specific operational, safety and environmental goals,” Dyce adds.
“In cost-sensitive environments where downtime and equipment failure carry high financial and safety consequences, the ability to design equipment that matches the needs of the installation exactly delivers real lifecycle value.
“Our customised approach also supports compliance with Environmental, Social and Governance (ESG) requirements, as bespoke components can be optimised for energy efficiency, recyclability and sourcing from local supply chains.”
The company’s vertically integrated facility, which is equipped with heavy-lift cranes, precision fabrication shops, spray booths, VPI varnish tanks and full-scale test bays, is geared to enable customisation of the full product range. It supports advanced processes, like OEM motor reconditioning, winding, coating and dynamic testing – all performed on site under ISO 9001:2015-certified quality management processes. Uninterrupted production is secured by a 600 kVA diesel generator.
Hexagon Electrical supplies products ranging from bespoke 20 MVA, 33 kV transformers for power utilities, to dual-speed flameproof motors designed for underground mining. The dry-type and oil-type transformer range supports diverse configurations – including shell/core, auto-transformers and reactors – engineered to match load profiles, harmonic requirements and spatial constraints. The company also produces flameproof and non-flameproof equipment, including motor control centres, remote monitoring units and substations, with control interfaces and housing layouts optimised to client specifications.
Ventilation and dust suppression fans are designed to meet precise airflow parameters, noise restrictions and safety thresholds for use in confined underground environments.
The portfolio of electric motors comprises high-efficiency flameproof, water-cooled, traction and winch models. Every unit can be adapted to environmental or application-specific criteria, including shaft configuration, enclosure rating, insulation class and thermal protection.
The flameproof auxiliary product line, including cable reels, lighting, sirens and spooling devices, can be specified for hazardous locations and is manufactured in compliance with SANS 10142‑1, 10242 and IEC 60079 standards.
All designs are certified by third party standards authorities, such as the SABS, MASC and Explolabs South Africa, Hexagon Electrical also invests in R&D to support enhanced safety and energy performance in the apparatus it supplies.
The company’s commitment to engineered precision is evident across the full spectrum of its operations. From R&D and prototyping, to manufacturing and after-sales service, Hexagon delivers tailored electrical systems that meet Africa’s toughest operating challenges safely, reliably and sustainably.
