Three-Phase Isolation Transformer – 800 kVA (Copper Windings, K-Factor 13, Dyn11)

is a high-performance isolation transformer specifically designed for applications with significant harmonic distortion. Its copper windings and K-Factor 13 rating effectively mitigate these harmonics, ensuring stable and clean power. The Dyn11 vector group contributes to balanced three-phase operation and minimal leakage reactance. Rated at 800 kVA with an efficiency exceeding 96%, this transformer is suitable for continuous operation up to 50 °C ambient temperature. Choose between the IP00 open construction for well-maintained environments and the IP23 enclosure for added protection against dust and humidity. It complies with IEC 61558-1, IEC 61558-2-4, and IEC 60076-1 standards, guaranteeing galvanic isolation and adherence to strict safety protocols. 🔧 Specifications:
