Product Introduction
The iron core of the oil type power transformer is crafted with fully oblique stepped joints, a design innovation that optimizes magnetic flux distribution, effectively eliminating localized magnetic saturation at core joints. This improvement significantly reduces no-load losses and current, while also lowering operational noise. To bolster short-circuit resistance, the core employs a tension-plate structure reinforced by multiple pressure bolts distributed around the clamping plates. The upper and lower clamping assemblies for high- and low-voltage windings are interconnected via support beams, ensuring structural integrity of the core.

Transformer Core Manufacturing Process
Transformer Manufacturing Process - Final Assembly
Final Assembly
The final assembly process commences with the extraction of the core and coil assembly from the vapor phase. Subsequently, all internal components are repressed according to the pressure values stipulated in the project specifications. To guarantee tightness, any residual water is thoroughly removed at this stage. Metal and fiber nuts are tightened as per requirements, and the electrical clearances are re-verified meticulously.
Next, the core and coil assembly is positioned inside the tank, which is then filled with oil to safeguard against air exposure. A cover assembly is subsequently installed to establish a connection with the sleeve. Once the enclosure has been welded, it undergoes a stringent leak - testing procedure. Following this, the galvanized radiator is attached to the tank. The unit is then drained, and the power inverter transformers is vacuum - filled, paving the way for the final testing phase.
During this process, the control box, along with any other monitors and components specified by the customer, are installed and properly connected. All externally welded components must be fitted accurately to the tank to ensure correct installation. These components will be removed before the completion of the multi voltage transformer's factory acceptance test.
Finished Enduring Hermetically Sealed Oil Filled Transformer
Structural characteristics of oil immersed self cooled transformers
The core limbs of the enduring power electronic transformer are coated with specialized end-face adhesive for silicon steel sheets, bonding laminations together post-curing to form a monolithic structure. For robust mechanical stability, the oil-immersed transformer's lower body is securely positioned against the tank wall using high-strength electrical laminated wood supports, guaranteeing reliable and vibration-resistant placement. These advancements collectively enhance efficiency, durability, and acoustic performance in oil immersed current transformer applications.
