ZGSL-Z-1500-13.8-0.415
YAWEI’s ZGS Series Radial Feed Pad-Mounted Transformer is a utility-grade, outdoor distribution transformer purpose-built for underground power distribution networks. The flagship ZGS-Z-1500/13.8-0415 model steps down 13.8kV primary voltage to 0.415kV secondary voltage, delivering 1500kVA of reliable power conversion for commercial and industrial clients. Housed in a lockable, weatherproof steel enclosure, this radial feed transformer eliminates the need for fenced enclosures, simplifies underground cable connections, and delivers up to 98.5% energy efficiency in a compact, easy-to-install design.

Our radial feed pad-mounted transformer reduces upfront infrastructure costs by ~25% compared to loop feed alternatives, with simplified cabling requirements and no complex switching gear. The high-efficiency core minimizes no-load and load losses, reducing ongoing energy expenses and delivering a faster return on investment for your distribution project.
With a footprint 35% smaller than comparable loop feed models, this pad-mounted transformer is ideal for space-constrained urban, residential, and commercial sites. The fully integrated, ground-level design fits easily on a compact concrete pad, with no need for additional civil construction or fenced security perimeters.
Engineered to withstand harsh outdoor conditions, our transformer features a corrosion-resistant steel enclosure, tamper-proof locking mechanisms, and wildlife-resistant design, with a 30-40 year design life. It resists weather, vandalism, and environmental damage, ensuring consistent, reliable power distribution with minimal unplanned downtime.
The plug-and-play radial feed design enables full installation and commissioning in just 6-8 hours, with only a concrete pad and electrical connections required. Ground-level access simplifies routine maintenance and inspections, with 50% fewer inspection points than loop feed models, reducing long-term operational costs and service downtime.
