    Core Advantage Of TGTpower 35kV Oil Immersed Transformers

    Low-Loss & Eco-Design

    Built with high-quality grain-oriented silicon steel (CRGO) cores with progressive step-lap joints, significantly lowering no-load loss and reducing operating noise well below industry NEMA limits.  

    High-Purity Oxygen-Free Copper Winding

    Windings are wound using premium oxygen-free copper strip/foil conductors, creating maximum dynamic short-circuit tolerance and eliminating axial magnetic thrust during surge events. 

    Airtight Elastic Corrugated Tank

    Utilizes a permanently sealed, elastic corrugated tank structure that automatically flexes to absorb the natural expansion/contraction of fluid, avoiding micro-leaks and reducing maintenance cycles.  

    Comprehensive Analog Diagnostics

    Factory-integrated with automatic pressure relief valves (PRV), dial-type thermometers, magnetic liquid level gauges (MOG), and gas relays for immediate signal tipping or alarming. 

    Packaging

    Reinforced Solid Wood Skid Pallets: Anchored firmly via pneumatic high-tensile steel straps onto custom-built, heat-treated wood skids matching ISPM 15 standards (Fumigation-Free) for immediate customs clearance.
