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.
We have an ISO 9001/2008/ SABS quality accreditation and are a SABS accredited production facility for electrical assemblies up to 10 kA.
