Product Overview

1000 kVA Pad Mount Three-Phase Oil-Immersed Distribution Transformer

When your project depends on reliable power delivery, you need a transformer built specifically for your requirements — not an off-the-shelf alternative adapted to fit. MPS’s 1000 kVA three-phase pad-mounted distribution transformer is custom-engineered from your Single Line Diagrams, UL Listed, and built to ANSI/IEEE standards at our U.S. manufacturing facilities. You get a solution matched to your exact electrical, environmental, and operational needs, backed by 24/7 engineering support and industry-leading lead times typically starting at 16–18 weeks depending on project scope and complexity.
