    1 & 3 Phase Pad-Mounted Transformers

    Three-Phase Pad-Mounted Transformer
    Single-Phase Pad-Mounted Transformer

    Underground Power Distribution — Residential to Industrial

    Pad-mounted transformers are the backbone of underground power distribution systems. Housed in tamper-resistant, ground-level steel enclosures, they eliminate the need for fenced substations and overhead lines — keeping communities safe while delivering consistent, reliable power.

    Single-phase units (10–500 KVA) are the standard for residential neighborhoods, subdivisions, and light commercial areas. Their compact, low-profile design provides safe voltage step-down where aesthetics and space matter.

    Three-phase units (75–10,000 KVA) serve commercial buildings, industrial facilities, shopping centers, and large-scale developments. They step down primary distribution voltages to utilization levels across a wide range of KVA ratings.

    Xplor Energy supplies both configurations new, and also provides expert repair and installation services. Every repaired unit undergoes complete core and coil inspection, retanking when necessary, full oil processing, and rigorous electrical testing to meet or exceed original manufacturer specifications — getting your equipment back online fast.
