Product Overview
BHP Power Block skids integrate medium-voltage switching, dry-type transformation, and low-voltage distribution on one structural base. Each unit is factory assembled, pre-wired, and factory tested before shipment, so site work is limited to setting the skid and terminating the external interfaces.
The platform uses a repeatable architecture for 1–3 MVA. The reference arrangement is a 3,000 kVA, 13.8 kV to 480Y/277 V skid for AI data centers, renewable plants, and industrial loads.
One Integrated Skid
- Factory assembled. Pre-wired and factory tested before shipment.
- Repeatable platform. A standardized architecture for 1–3 MVA.
- Built for critical loads. AI data centers, renewables, and industry.
Integrated Equipment
The reference 3 MVA skid is arranged as three coordinated sections on a common base.
- 01 MV disconnect — 600 A continuous, 31.5 kA short-time withstand. Incoming medium-voltage switching for the skid. At 3,000 kVA and 13.8 kV, transformer primary full-load current is 126 A, so the 600 A disconnect is a standard 15 kV-class rating above that current.
- 02 Dry-type transformer — 3,000 kVA. Steps 13.8 kV down to 480Y/277 V. Dry-type construction is used where a liquid-filled transformer is not the preferred choice.
- 03 LV switchboard — 4,000 A main bus. Distributes the transformer secondary. At 3,000 kVA and 480 V, secondary full-load current is 3,608 A, so the 4,000 A bus is sized above that current.
- 04 Panelboard — Branch circuit distribution unit, fed from the LV switchboard. Provides multiple outgoing feeder circuits to supply downstream loads.
Applications
- AI data centers and other critical facilities
- Renewable generation and plant interconnection
- Industrial and process power distribution
