PRODUCT LINE 02 · PAD-MOUNTED

Pad-Mounted Transformers

Dead-front, compartmentalized transformers for commercial estates, solar farms and underground distribution — engineered to ANSI/IEEE C57 with NEMA 3R enclosures and UL / CE certification options.

Single-Phase

Single-phase pad-mounted, 15–250 kVA

Modular compartmentalized layout with high-voltage and low-voltage cable terminal compartments clearly separated. Designed for outdoor residential and small commercial distribution.

Three-Phase

Three-phase pad-mounted, 45–5,000 kVA

Laminated cold-rolled silicon-steel core, extremely high efficiency and low heat generation. NEMA 3R weatherproof enclosure for indoor or outdoor installation. Loop feed or radial feed.
