Compact & Packaged Substations
Compare complete equipment packages with individual transformer supply.
Define whether you need a transformer alone or an integrated package with switchgear, protection, auxiliaries and structural interfaces. Include the single-line diagram, site layout, access limits and division of installation work so the quotation covers the equipment you actually need.
Compact & Packaged Substations
Pad-Mounted Compact Secondary Unit Substation
A factory-assembled compact secondary unit substation — incoming medium-voltage switching, distribution transformer (≤2500 kVA) and a low-voltage section in one weather-tight pad-mounted enclosure for 15/25 kV class service, 60 Hz. Designed to IEEE C37.121, ANSI C57.12.34 and IEC 62271-202; UL/CSA certifiable.

Power equipment for AI data centers: what changes when racks hit 100 kW
AI training loads have pushed rack densities past 100 kW and substation lead times past three years. This is what each layer of the data-center power chain — transformer, switchgear, energy storage — now has to deliver, and where projects actually compress the schedule.

NEMA vs. IP enclosure ratings: specifying outdoor power equipment
NEMA enclosure types and IEC 60529 IP codes both rate ingress protection, but they are not interchangeable — NEMA 250 also tests corrosion, icing and hosedown, which the IP code omits. For North American power equipment, specify a NEMA type and treat IP as a supplement.

Should your facility take medium-voltage service? Primary metering and customer-owned substations
Taking medium-voltage utility service means owning the step-down transformer and the substation behind it, in exchange for a lower primary-metering rate. It pays off for large, steady loads but shifts transformer losses, maintenance, and protection to the buyer. Here is how to weigh the trade-off.

For Canadian and US projects, include the utility specification, service frequency and required approvals. State whether the order is for the transformer alone or an integrated equipment package.
