Padmount transformers in single- and three-phase configurations — new, remanufactured, and rental options for utilities, EPCs, industrial buyers, and renewable projects. On the ground, when factory lead times slip.
Need a fast quote? Send KVA, primary voltage, secondary voltage, phase, fluid type, front/dead front preference, quantity, ship-to location, and required delivery date.
Our padmount transformer inventory is built for buyers who cannot afford to wait on factory lead times. We stock units across the KVA, voltage, and configuration combinations most commonly specified for commercial, industrial, utility, and renewable projects.
Browse current availability in the H2LV store, or send your specs and our team will match a unit from inventory.
We stock both single-phase and three-phase padmount transformers.
If your project mixes single-phase and three-phase loads, send the one-line and we will quote each unit accordingly.
We source padmount transformers across the full distribution range:
If your load profile sits between standard ratings, our team can help you pick the right size without overbuilding. Run a quick check with our transformer calculator before submitting specs.
The two most common secondary voltages on padmount transformers are 480Y/277V and 208Y/120V. Availability shifts by KVA band:
Other secondary configurations are available on request. Send your spec and we will confirm.
We help buyers spec the right unit every day. Send what you have and we will fill in the gaps.
Primary voltage is set by the utility distribution system feeding the pad. We stock and source padmount transformers in the standard utility classes:
If your utility specifies a non-standard primary voltage or BIL, send the spec and we will source accordingly.
We carry new padmount transformers in stock and ready to ship. New units come from established suppliers and are matched to applicable ANSI/IEEE and DOE efficiency requirements where required, with documentation available on request.
Depending on the unit and availability, H2LV can provide nameplate photos, spec details, test documentation, and shipping information before release.
If your spec calls for a unit we do not have on hand, we can typically source it faster than going direct to factory. Tell us what you need and we will tell you how soon you can have it
Not every project needs a new-build unit. H2LV can help source remanufactured padmount transformers when the spec, timeline, and budget point in that direction, and rental padmount transformers when you need temporary power, emergency replacement, or bridge equipment while a permanent unit is being built or repaired.
Need a configuration that is not listed here? Send your KVA, voltage, phase, fluid, and front/feed requirements, and we will check stock or source the closest matching padmount transformer.
Most quote turnarounds slow down because key spec details are missing. Send what you have, and our team will fill the gaps. The more of the following you can confirm up front, the faster we can match a unit:
If your installation has fire safety or environmental constraints, FR3 is typically the right call. We stock both.
Padmount transformers ship with a defined switching, tap changing, and protection package. Common configurations include:
Tell us your protection scheme and we will quote accordingly.

Padmount transformers use a layered fusing approach to protect the transformer and coordinate with upstream protection.
Terminations on dead front units use 200A or 600A bushing wells with deadbreak elbow connectors. Live front units use bushing terminations sized to system voltage.
We match units to applicable ANSI/IEEE standards and DOE efficiency requirements where required, with documentation available on request. Standard operating details: 65°C average winding temperature rise, BIL sized to primary voltage class, and ANSI 70 light gray paint finish.
Padmount transformers are designed for outdoor, ground-level installation in publicly accessible environments. Standard tamper-resistant and field-service features include:
Padmount transformer options can make the difference between a unit that technically fits and a unit that actually works for the site, utility standard, and long-term operating conditions. Send the accessory list, utility spec, or engineer’s notes up front, and we will match the configuration before the unit ships.
For installations near buildings, in vaults, or in fire-sensitive environments, high fire point liquids reduce fire risk significantly. Temperature rise options affect thermal headroom and unit life.
Dead front padmount transformers use bushing wells with elbow connectors sized to the load.
Specify bushing type up front. Mismatched bushing ratings cause field returns.
Standard and optional accessory packages include:
Send your accessory list and we will match the configuration.
We supply padmount transformers for commercial, industrial, utility, renewable, healthcare, data center, and critical-infrastructure applications.
Office towers, mixed-use developments, retail centers, and high-rise residential projects use padmount transformers for primary step-down service, HVAC, elevators, life safety, lighting, and receptacle loads.
Hospitals, medical campuses, and universities use padmount transformers for mission-critical distribution where reliability, fire safety, and service continuity matter.
Manufacturing plants, processing facilities, warehouses, and logistics centers use padmount transformers for plant distribution, facility expansions, production loads, and emergency replacement.
Solar farms, wind sites, microgrids, oil and gas operations, utilities, and co-ops use padmount transformers for collection, tie-in, step-up, field distribution, and planned or emergency replacement needs.
Data centers, crypto mining facilities, and other critical-infrastructure projects use high-KVA padmount transformers for reliable power distribution, strict lead-time requirements, and fast deployment.
Send your specs, one-line, or nameplate details, and we will help match the right padmount transformer for your load, site, and utility requirements.
Start with the connected load, growth allowance, and required secondary voltage, such as 208Y/120V or 480Y/277V. We will help confirm the right KVA rating and secondary configuration without overbuilding.
Most modern installations use dead front with loop feed, while live front or radial feed may apply for specific utility or stub-end requirements. Send your one-line and we will confirm the right setup.
Confirm fluid type, temperature rise, bushing rating, gauges, alarms, and protection options. If you already have an accessory list or engineer’s spec, send it as-is and we will match the configuration.
Not sure which configuration fits your project? Send the specs you have, and our team will help confirm the right padmount transformer before quoting.
H2LV supplies padmount transformers across the United States for planned procurement, multi-site rollouts, facility expansions, emergency replacement, and temporary rental needs.
We ship from regional inventory points and arrange freight around your project timeline. For planned orders, we coordinate delivery with construction schedules. For emergency replacements or rental needs, we can arrange expedited freight to most locations in the lower 48.
We support EPCs, general contractors, utilities, co-ops, industrial facilities, renewable developers, data centers, and critical-infrastructure buyers with padmount transformer sourcing, documentation, lead-time coordination, and shipping.
H2LV is built around a simple idea. When you need a padmount transformer, you should be able to talk to a team that knows the equipment, has stock on the ground, and gives you straight answers on price and lead time.
We carry deep inventory across new units. We move fast on emergency orders. We do not push you toward a unit that misses your spec. And we back every transformer we ship with technical support from people who have spent careers around this equipment.
If your last vendor sent back a quote that read like a stall, send us your specs and see the difference.
Send your padmount transformer requirements and we’ll respond with availability, pricing, documentation, and a real lead time for new, remanufactured, or rental options.
If this is an emergency replacement, mention that in the request so we can prioritize availability and freight options.
