Medium Voltage Transformer

Option from 5 kV to 35 kV and below

When you’re energizing critical infrastructure, you need more than just equipment; you need reliability, speed, and support you can count on. Our medium voltage transformers step power down from distribution lines to the level your operation depends on, whether you're expanding a facility or installing new service.

JCL Offers Medium Voltage Solutions That Connect & Protect the Evolving Grid

Understanding Medium Voltage Transformer Options & Applications

No two projects are the same, so your power distribution solution shouldn’t be one-size-fits-all. That’s why our step-down transformers come in multiple configurations, supporting voltages from 1 kV to 34.5 kV. Whether you're powering equipment, a facility, or infrastructure, we help you find the right fit.
