South African electrical enclosure specialist Power Process Systems (PPS) has successfully completed the full refurbishment of four mini substations in the Katlehong area, reaffirming its leadership in delivering cost-effective infrastructure modernisation solutions for municipalities and utilities.
The project scope included a complete renewal of the substations’ outer shells and critical inner works, covering the Ring Main Units (RMU), transformers, and low-voltage (LV) panels. By restoring the units from a damaged state to full operational capacity, PPS has extended the life of the substations without the need for costly replacement.
Beyond revitalisation, the refurbishment introduced added value through built-in vandal protection and safety features for the general public, enhanced monitoring, improved surveillance, and greater auditability for staff maintenance. These measures ensure not only improved reliability but also long-term sustainability of municipal electricity networks.
“At PPS, we believe refurbishment offers municipalities a smart, economic pathway to modernising their networks. By extending the lifespan of existing infrastructure while embedding new security and monitoring features, we provide solutions that are both practical and future-ready,” comments Nhlanhla Zondo, Director at Power Process Systems.
The successful completion of the project demonstrates PPS’s commitment to supporting South Africa’s energy infrastructure with innovative, cost-effective, and sustainable solutions. “Electricity underpins economic development and quality of life. Our products ensure that power is delivered safely and reliably, helping utilities recover revenue and communities thrive,” concludes Zondo.
