Features
1. Scientific and advanced design scheme
Harness the power of technology with our scientific and advanced design scheme. Using sophisticated computer software, we precisely analyze the winding electric field under high voltage, ensuring the winding structure withstands high-voltage impulses. Our scientific insulation architecture guarantees safe operation, while strategic calculations of magnetic leakage and temperature fields secure stellar performance. The optimized lamination design is a masterstroke, reducing magnetic distortion and boosting no-load efficiency.
2. Iron Cores
Crafted from superior grain-oriented cold-rolled silicon-steel sheets, our iron cores feature razor-thin burrs thanks to advanced shearing technology. The innovative multi-step and 45° all-leaning joint design dramatically reduces no-load loss, current, and noise. A robust board structure core clamping device offers unmatched mechanical strength, while bolstered nails ensure consistent transformer axis padding block pressure.
3. High purity oxygen free cooper windings, reduce the load loss
Our high purity oxygen-free copper windings are a marvel of engineering, directly wound on the insulation barrel for utmost precision. With chamfering spacers and padding blocks harmonizing the electric field, stability is enhanced. The BDK-80M synchronized lifting-up equipment secures the axial position of the windings, fortifying their axial strength.
4. Tank
Engineered with precision, our tank boasts a wide-width steel plate, minimizing welding seams on the sleek flat roof. This folded plate-type tank showcases a refined appearance coupled with robust mechanical strength, having passed standard positive pressure and vacuum tests. The innovative welding technology and groove-type flange promise long-lasting usability without leakage. Our wide plate radiation system, complemented by heavy-duty, low-noise blowers, optimizes heat dissipation and boosts efficiency. The seamlessly integrated capsule-type conservator delays oil aging under vacuum conditions, elevating the electric strength.
5. Protection System
Our sophisticated protection system integrates Pt100 thermal resistors within the transformer body for precision temperature control. A pressure relief valve with contacts atop the tank, an oil indicator with contact, and vacuum relays on the conservator ensure comprehensive monitoring. The pollution-retardant porcelain oil-type bushings for both HV and LV extend insulation capabilities in high-pollution settings. With stainless steel padding plates and a terminal case, the transformer exudes elegance and durability, ensuring an immaculate appearance.
