Product Introduction

Our 280KVA 3 Phase 380V Industrial Power Transformer (SG Series) is a heavy-duty industrial-grade dry-type power solution, purpose-built for reliable, high-efficiency power conversion in demanding global industrial environments. With a standard 280KVA rated capacity (fully customizable) and flexible voltage configurations (input 220V/380V/400V/415V, output 220V/380V/440V, customizable), this transformer is fully compatible with 50/60Hz electrical systems, delivering ±2% output precision with no additional waveform distortion. It is the ideal power choice for factory power distribution, photovoltaic systems, EV charging stations, AI data centers, CNC machine tools, laser cutting machines, and precision instruments, trusted by electrical engineers and industrial operators worldwide for 24/7 uninterrupted operation.

Key Features & Competitive Advantages

Continuous Full-Capacity Operation: Optimized for non-stop industrial loads, with high-purity high-conductivity windings that deliver low temperature rise (＜80K), ensuring stable long-term performance even in harsh working conditions.
Ultra-Efficient Energy-Saving Design: New high-permeability silicon steel core enables noise-free (＜55dB) operation, ultra-low energy losses, and ≥90% working efficiency, drastically cutting long-term operational electricity costs.
Superior Electrical Safety & Insulation: Class F insulation, 3500V di-electrical strength withstand, ≥5MΩ insulation resistance, and 4% short-circuit resistance provide maximum protection for personnel and sensitive industrial equipment.
Rugged Customizable Protection: IP23/IP44/IP56/IP64 customizable enclosure, reliable high-insulation terminals, safety trip lock, and heavy-duty construction ensure durability in both indoor and outdoor industrial sites.
Smart User-Centric Design: Digital display for real-time working status monitoring, input/output indicators, optimized heat emission holes, convenient wiring structure, and brake-equipped universal wheels simplify installation and maintenance.
