Product Introduction

  • The S(F)Z11 Series 35kV Oil-immersed Power Transformer is a high-performance, highly reliable power distribution device, specifically designed for urban distribution networks, industrial parks, and power systems. This series uses high-quality cold-rolled oriented silicon steel sheets for the core, combined with advanced lamination techniques and a fully sealed oil tank design, ensuring stable operation under high loads and complex conditions. The transformer supports both off-load tap changing (OLTC) and on-load tap changing (OLTC) modes, meeting the voltage regulation and load capacity requirements of various distribution networks.
