Description
Our isolation transformers are engineered with precision winding technology, high-grade silicon steel cores, and reinforced insulation to ensure safety, reliability, and durability. Designed for industrial, commercial, and specialized applications, they effectively isolate power sources to protect sensitive equipment from electrical noise, surges, and interference. With capacities ranging from 45–3000 kVA and voltage levels of 380V–660V, these transformers are widely used in manufacturing plants, medical facilities, data centers, and marine power systems.
Advantages
• Nomex®-insulated coils processed through VPI for a sealed, high-strength insulation system for long-lasting durability.
• Efficient heat dissipation with Nomex® insulation for reliable operation at temperature above 200°C.
• Effectively suppresses electrical noise, voltage spikes, and harmonics to improve the stability of connected equipment.
• Optional stepping up, stepping down, or maintaining voltage as needed.
• Nomex® paper burns cleanly without releasing harmful substances, ensuring environmental sustainability.
