Mitigating Transformer Supply Chain Issues

Transformer Supply Chain

Transformers play a critical role in electrical power systems, enabling efficient transmission and distribution of electricity. However, the availability and reliability of transformers can be affected by various factors, including limitations in the transformer supply chain. Therefore, the importance of transformer monitoring cannot be overstated, as it helps ensure their optimal performance, prevent failures, and enhances overall system reliability. It is important to consider the limitations of the transformer supply chain and highlights options for maintaining a robust electrical power infrastructure.

Limitations in the Transformer Supply Chain

There are four main limitations in the Transformer Supply Chain

  1. Manufacturing Capacity: The production capacity of transformer manufacturers can sometimes be insufficient to meet the growing demand for transformers. This limitation can result in longer lead times for new transformers, delays in project implementation, and potential bottlenecks in the supply chain. 
  2. Raw Material Availability: Transformers require various raw materials, including copper, aluminum, steel, insulating materials, and cooling fluids. Fluctuations in the availability and prices of these materials can impact transformer production and increase costs. Supply chain disruptions, such as natural disasters or geopolitical events, can further exacerbate the raw material availability challenge. 
  3. Transportation and Logistics: Transformers are large and heavy equipment, requiring specialized transportation and logistics arrangements. Delays or issues in transportation can lead to project delays and hinder the timely deployment of transformers to their intended locations. Infrastructure limitations, such as inadequate roads or port facilities, can add further complexity to the supply chain. 
  4. Quality Control: Maintaining consistent quality across the production of transformers is crucial. However, the quality of transformers can vary due to factors such as different manufacturing processes, varying quality control measures, or inadequate adherence to industry standards. Inconsistent quality can lead to premature failures, increased maintenance costs, and reduced system reliability. 

Mitigating Supply Chain Issues

There are several options to help avoid supply chain issues.  

  1. Extend the life of existing transformers: We recommend implementing transformer monitoring. Transformer monitoring provides early fault detection, guidance on optimal asset utilization, and predictive maintenance. It allows users to make decisions based off of data.  
  2. Approve new suppliers or accept alternative designs: It is important to monitor new designs and suppliers to ensure quality and performance
  3. Rewind transformers: When it’s time to replace the transformer, one alternative route to buying new is to remanufacture transformers with Jordan Transformer. Jordan Transformer specializes in remanufacturing step-down substation transformers to make them work better than new ones. They have shorter lead times compared to purchasing new and users can select the exact upgrades that are required. Learn more about remanufacturing transformers at 


The transformer supply chain faces various limitations, including manufacturing capacity, raw material availability, transportation challenges, and quality control issues. It is important to plan ahead and consider options to keep your system working properly.
