Neel Electric’s ZSII/ZSI3 series 10kV rectifier transformers deliver low loss, high reliability, and strong overload capacity for electrolysis and metallurgical applications – backed by a trusted China OEM manufacturer.
Low Loss & High Reliability
Our newly designed ZS11 and ZS13 Series 10kV Rectifier Transformers are engineered to meet the rigorous demands of modern industrial power systems. Fully compliant with the latest national standard GB/T6451-2023, these transformers represent a significant leap in energy efficiency and operational stability. Widely adopted in domestic electrolysis, chemical, and metallurgical industries, our rectifier transformers are renowned for their low noise, superior overload capacity, and exceptional reliability.
Premium Core Material for Ultra-Low Losses: We utilize high-grade 30Q120 oriented cold-rolled silicon steel sheets for the magnetic core. The core features a fully inclined lap joint structure (fully mitered joints), which significantly reduces magnetic resistance and ensures minimal no-load losses.
Advanced Winding Technology: The windings are crafted from high-purity oxygen-free copper conductors. We offer two optimized winding configurations—double winding and split winding structures—tailored to specific rectification needs. This design enhances short-circuit impedance stability and mechanical strength.
Superior Insulation & Craftsmanship: By integrating top-tier insulation materials and components from industry-leading manufacturers, combined with novel structural designs, our transformers deliver outstanding dielectric strength and thermal stability.
