With aging infrastructure across South Africa’s power grid, refurbishment and maintenance of existing transformers, particularly in mining and at municipal/decommissioned-grid level, is in growing demand.
Wiselights takes a holistic approach: we don’t just manufacture, we support transformers for their full working life.
Our design process starts with custom specifications for magnetic cores and coils, followed by assembly, insulation installation and placement into protective tanks — engineered to deliver accurate voltage regulation for the specified power rating. Manufacturing follows strict quality control at every stage, so each transformer is built to perform reliably under real operating conditions.
Specialised maintenance, diagnostics and restoration services that keep transformers operating safely, efficiently and reliably — extending working life and preventing costly, unplanned downtime. Our systematic approach identifies and repairs or refurbishes critical components including coils, insulation and insulating oil.
Every transformer we manufacture undergoes mandatory, standardised electrical and mechanical testing before shipment, performed to IEC 60076 to confirm the unit is defect-free and performs to design specification. These tests verify insulation integrity, winding accuracy and operational reliability — our core quality control checkpoint before any unit reaches a client site.
End-to-end engineering, fabrication and assembly of durable enclosures for electrical distribution infrastructure, manufactured with a focus on sustainability and reduced environmental impact.
Engineering, development and production of AVR/stabilizer units built to protect sensitive loads from voltage fluctuation.
Our relationship with a client doesn't end at delivery. We maintain ongoing contact after the sale to support long-term performance and build trust — because a client's success with the product matters more to us than the transaction itself.
A proactive maintenance process — not unlike a blood test for your transformer. We collect small oil samples and analyse them for contamination, wear debris and fluid health, allowing early identification of developing faults, reduced unplanned downtime, and optimised service life.
We remove contaminants — water, solid particles, gases and sludge — from transformer oil to restore its insulating and lubricating properties. This extends service life, improves efficiency, and helps prevent premature failure caused by oxidation or contamination.
