Description
Our 110kV oil-immersed power transformer core utilizes premium grain-oriented silicon steel sheets, meticulously stacked in multiple steps, with cured surface paint. This design delivers superior performance characterized by exceptionally low loss and minimal noise emissions.
Features
Robust Short-Circuit Strength: The winding employs a sturdy inner-and-outer brace structure. High-strength cardboard tubes are strategically placed between windings and between winding and core, ensuring excellent short-circuit withstand capability.
Enhanced Tank Durability & Aesthetics: The tank wall features a one-piece formed, corrugated structure, significantly increasing mechanical strength while providing a clean and visually appealing profile.
Secure Transport & Operation: An omnidirectional positioning structure firmly secures the core and coil assembly within the tank, guaranteeing stability during both transportation and service operation.
Versatile Application: Designed for reliable service in power plants (generating stations), substations (distribution stations), and industrial facilities.
Comprehensive Quality Assurance: Our stringent manufacturing processes are governed under the ISO 9001 (Note: ISO 19001 is incorrect, it's 9001 for Quality Management; corrected here) quality management standard, guaranteeing product excellence and consistency.
Customization Capability: To meet specific project requirements, we can provide solutions with other voltage ratios, vector groups (YD connections), and rated capacities upon request, beyond the standard models listed.
