Padmount transformers.

A failed unit. A custom specification. A deadline that's getting too close. Whether you need a transformer built to your requirements, delivered quickly, or supported in the field, we'll help you find the right solution.

What we get called for

Most conversations start here.

Start with the problem you're trying to solve.
“I have limited specifications. Can you help?”
JCL
Absolutely. We'll walk through your application, system requirements, and project needs to help identify the right transformer.
“Do you build new transformers?”
JCL
We don't manufacture transformers ourselves. We source new transformers from qualified manufacturers and can help identify the right unit for your application and requirements.
“What standards do your transformers meet?”
JCL
We'll match the transformer to the applicable industry standards and your project requirements, and provide the relevant specifications with your quote.
“Can you meet a tight delivery schedule?”
JCL
We'll provide a realistic lead time based on the transformer and project requirements, keep you updated as the order moves forward, and help identify options when schedules are tight.
“What is the country of origin?”
JCL
Country of origin depends on the specific transformer. We'll provide that information for the unit you're quoting so you know where it was manufactured.
“Do you complete the installation?”
JCL
Yes. JCL provides field services including transformer installation, rigging, testing, oil filling, and related support.
“What is the warranty?”
JCL
Warranty terms vary by transformer and application. We'll provide the applicable warranty terms with your quote and can also support ongoing service and maintenance after installation.
Padmount solutions

Three ways we help solve transformer problems.

Every project looks different. Some require a custom-built transformer. Others can't wait. Sometimes the priority is keeping power on while a replacement is being built. We help customers find the right path based on their timeline, specifications, and operating needs.

Engineered products

For projects that require custom voltages, kVA ratings, impedance, taps, accessories, utility requirements, or other project-specific specifications.

Quick Ship

When timing matters, we'll help you identify available inventory that meets your project requirements and gets to your site as quickly as possible.

Rentals + Field Service

When equipment fails, temporary rental transformers and field service can keep operations moving while your transformer is repaired or a new unit is being built.

Details that make ownership easier

The right transformer is easier to own.

Every padmount is configured to your project's utility specifications, voltage requirements, and long-term operating needs. From installation through decades of service, every detail is selected with ownership in mind.

A project is more than a transformer

More than a transformer. A partner through the project.

Delivering the transformer is only one part of keeping a project on schedule. We help coordinate equipment, logistics, testing, field service, and ongoing support so you spend less time managing vendors and more time moving the project forward.

Every handoff is another chance for something to fall through the cracks.
With JCL
One team helps coordinate every handoff.
From the first conversation through energization—and whenever you need us afterward. One number the whole way.

Let's find the right solution.

Whether you're planning a project, replacing a failed transformer, or working through a complex specification, we'll help you determine the best path forward.
