Product Overview
The American Pad-Mounted Transformer is a compact, fully enclosed power distribution unit designed for medium and high voltage (MV & HV) systems.
It integrates the transformer, switchgear, and protection devices into one sealed box, ideal for outdoor applications requiring safety, reliability, and easy installation.
Available in capacities of 75kVA, 152kVA, and 225kVA, this three-phase outdoor transformer is widely used in urban power networks, industrial zones, commercial centers, and renewable energy projects.
Key Features & Advantages
✅ Compact Integrated Design – Combines transformer, load break switch, and fuse in one sealed box, saving installation space.
✅ Fully Sealed and Maintenance-Free – Oil-immersed tank with hermetically sealed structure ensures long service life and prevents moisture ingress.
✅ Safe and Reliable Operation – High insulation level, low noise, overload capability, and explosion-proof design.
✅ Flexible Installation – Suitable for underground power networks and outdoor areas without transformer rooms.
✅ Energy Efficient – Low loss, low partial discharge, and compliant with IEC and ANSI standards.
✅ Aesthetic Appearance – Green outdoor cabinet design blends into residential or park environments.
