Features
1. The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, with fully oblique joints and a five-step stacking method. Both the core column and the iron rod have multi-stage circular cross-sections, resulting in lower no-load losses and noise.
2. Depending on the transformer capacity, the high-voltage conductor uses double-glass enameled copper wire with H-class fiberglass felt insulation between layers; the low-voltage conductor uses copper foil winding with epoxy resin pre-impregnated cloth insulation, providing high mechanical strength and resistance to sudden short circuits.
3. The clamps use a low-magnetic steel pull plate and clamp matching structure, and are sandblasted and powder-coated, resulting in an aesthetically pleasing overall structure and high mechanical strength.
4. Each phase is equipped with an independent axial flow fan and a separate temperature controller, effectively reducing temperature rise, increasing transformer output capacity, and ensuring safe transformer operation.
