Adopt high-permeability grain-oriented cold-rolled silicon steel sheets, cut by advanced German automatic shear line with burrs within 0.02mm. 2. Apply non-upper yoke lap joint and 45° full miter structure.

Laminated sheets are integrally bonded with epoxy resin for high rigidity and vertical precision, improving no-load performance and reducing noise. 3. Reinforced with bracing plates, fiber band binding, counter-pressure bolts and three-point fixing structure.

The internal unit can resist transportation vibration without displacement. Winding: 1. The HV coil adopts an interleaved-continuous structure to realize uniform impulse voltage distribution. All stays and pads are chamfered to ensure stable and reliable insulation performance. 2.

A zigzag oil guide structure is arranged inside windings for comprehensive cooling, which reduces temperature rise and hot spots and extends insulation service life.

Independent regulating windings for HV and MV balance ampere turns, reduce axial short-circuit electromagnetic force, and strengthen the transformer's sudden short-circuit withstand capability. 3. The winding features a radial zero-clearance design.

All components between the core, low-voltage paper sleeve and each winding are fully dried and closely assembled, ensuring excellent overall compactness and concentricity. Oil Tank and Accessories: 1.

The tank wall is integrally folded into a seamless corrugated structure with wide steel plates, cutting down welding seams and upgrading mechanical strength. The corrugated structure also optimizes heat dissipation and noise reduction.

Secondary circuit wiring ducts and control cabinets are made of stainless steel for a neat and aesthetic appearance. 2. All sealing surfaces are precision-machined and equipped with high-grade sealing materials. 3. Double sealing grooves are designed on the tank edge.

The outer sealing layer provides atmospheric and UV shielding to protect inner seals, effectively prolonging sealing life and improving equipment operational reliability. After Sales Service Standard Warranty: 12 months or 2,000 operating hours (whichever comes first).

Global Support: 24/7 technical assistance and spare parts supply. Training: On-site or remote operation/maintenance training. FA;load loss means winding copper loss under rated current.
