Proven Track Record in the Field
Why Mobile Substations Matter More Than Ever
Mobile substations have become essential assets in today’s strained energy landscape. But it’s not just about having a mobile substation ready, it’s about having one built your way, for your real-world deployment needs. From site-specific applications to system compatibility, Jordan Transformer delivers mobile substations engineered to perform under demand.
-
Backlog crisis at U.S. suppliers is forcing utilities to wait years.
-
Preconstruction and new construction planning are essential as the grid strains under renewable growth, rising loads, and aging infrastructure.
-
Broadening applications of Mobile substations give you interim capacity, emergency support, and expansion flexibility.
-
Limited number of suppliers risks outages, lost capacity, and higher costs.
Purpose-Built or Refurbished, Your Way
Jordan Transformer mobile substations are newly engineered builds. Each one is designed from the ground up using industry-standard protection components, customer specifications, and field-proven design practices. But when a new build isn’t the right fit, we also offer remanufacture options that deliver the same high standards at even shorter lead times.
We manage the entire process from design to parts sourcing, fabrication, and testing. This gives you full transparency, tighter quality control, and performance you can trust in real-world conditions.

Performance Delivery You Can Count On
We target delivery windows shorter than other OEMs. Our goal: predictable performance. Once your specifications are defined, we map every milestone. Just a clear path that keeps you informed on your project progress. Whether you're addressing an emergency or planning maintenance, you get delivery you can actually plan around.
Built and Tested for Growing Grid Demands
Each Jordan mobile substation is engineered for actual utility conditions: forces, thermal extremes, space constraints and electrical ratings. We design for the realities your equipment will experience. Every unit undergoes rigorous design and testing to meet IEEE C57.12 standards and utility specs before delivery.
That means proven performance under load per IEEE C57.12 for decades of service. You're not getting a prototype. You're getting a substation that's ready to work for decades.

Popular Configurations
Whether you’re matching existing specs or starting from scratch, we support a wide range of configurations. Our mobile substations and transformers are built or remanufactured around your system requirements, not forced into generic templates. From voltage ranges to protection packages, we’ll align with your goals and deliver exactly what your grid needs.
Jordan Transformer: New vs. Remanufactured
Both our remanufactured and new units follow the same rigorous QA process, with remanufactured units delivering like-new performance and reliability you can trust. Jordan Transformer helps you plan with confidence.

Frequently Asked Questions
Frequently Asked Questions
Mobile substations provide a fully functional, temporary substation solution, whereas mobile (portable) transformers are just one component of that substation solution.
A mobile (portable) transformer is a single transformer able to be loaded on a truck used to replace a damaged or offline transformer in a substation.
While a mobile substation is a complete, transportable electrical substation, typically on an 18-wheel trailer, containing a power transformer with cooling capability plus other necessary substation equipment like switchgear, circuit breakers and extensive controls.

Mobile Transformer |
Mobile Substation |
|
Definition |
A single electrical transformer unit that is designed to be easily moved and installed in an existing substation. |
A complete, transportable electrical substation built on a mobile platform, typically an 18-wheel semi-trailer. |
|
Components |
Just the transformer itself. |
A power transformer plus other key substation components like switchgear, circuit breakers, isolators, and control panels. |
|
Function |
Replaces a traditional, fixed transformer for emergencies. |
Provides a temporary, fully functional power substation source for a specific location and specific power and voltage ratings. |
|
Use Case |
To temporarily replace a single broken or offline transformer in a permanent substation (aka spare portable transformer). |
To provide temporary power during a permanent substation's maintenance, or for construction projects, and disaster relief. |
|
Complexity |
A single component. |
A complex, integrated substation system. |
Jordan Transformer does not lease mobile substations. We build new or remanufacture existing utility mobile substations back to original OEM specifications.
Leasing Options and Agreements from Field Service organizations, such as Siemens, are typically for short-term rentals and are ideal for emergency power restoration or planned maintenance periods.
Warranty for new mobile substations are typically 5 years from delivery. A significant impact on warranty is the maintenance of the mobile substations from being idle or transported for long distances. Mobile substations are designed to be local short hauls applications only.
Remanufactured mobile substations will have a reduced and itemized warranty, commonly less than 2 years (12/18 months), based upon the reuse versus replacement of key components such as transformer accessories, switch gear components, controls, and trailer.
