Practical tips for customers

• Engage early for asset-intensive projects to secure suitable production slots and scheduling, particularly for turnkey transformer requirements.
• Consider combining refurbishment and maintenance work with oil purification or moisture testing to optimise downtime and extend transformer life.
• Utilise on-site oil purification capabilities to improve oil quality and electrical insulation, potentially increasing KV tolerance and reducing failure risks.
• Request infrared scanning reports and protective equipment evaluations as part of a proactive condition monitoring programme.
• Clarify project scope, including transformer type, voltage, kVA rating, and installation environment, to ensure the proposed solutions meet the exact operational needs.
• Plan for both delivery and on-site service — the company maintains a delivery capacity with fleets capable of handling sizable transformers and equipment across Gauteng and surrounding provinces.
