YUGUANG Skid Mounted Substation Transformer

Modular, Turnkey Power Solution for Data Centers, Industrial, and Utility Applications

YUGUANG Skid Mounted Substation Transformers are factory-assembled, modular power units designed for rapid deployment, minimal civil work, and reliable performance. These compact, transport-ready units integrate medium-voltage switchgear, dry-type transformers, and low-voltage distribution panels on a single skid, enabling plug-and-play installation and optimized space utilization.

Skid mounted transformers are widely used in data centers, industrial facilities, renewable energy projects, and utility grids, providing a safe, efficient, and scalable power solution.

Why Choose Skid Mounted Transformers for Data Centers

 Fire Safety and Indoor Installation

For mission-critical data centers, fire safety is a top priority. Dry-type skid mounted transformers eliminate flammable oil, reduce fire hazards, and simplify fire protection requirements. Their epoxy resin cast coils provide excellent insulation strength, low partial discharge, and long-term reliability, ensuring continuous operation under full-load conditions.

 Rapid Deployment & Modular Design

YUGUANG skid mounted units are pre-assembled and factory-tested, reducing on-site installation time and minimizing civil construction. The compact skid design saves space, making them ideal for urban data centers, industrial campuses, and temporary power installations.

 Robust and Relocatable

Built on a rugged steel skid, these units can be transported or relocated easily. They support modular expansion and adapt to changing project requirements, making them suitable for both permanent and temporary installations.
