(I) Product Introduction

This product is an indoor, three-phase, double-winding, cast-resin encapsulated (SCB) high-efficiency energy-saving dry-type transformer, specifically the triangular three-dimensional encapsulated dry-type transformer of SCB11/12/13/14/18 series featuring high technical content and advanced performance. Compared with peer products, it boasts prominent strengths including symmetrical three-phase magnetic circuit, low noise, superior short-circuit withstand capability and favorable cost performance.

① Adopts triangular three-dimensional core to realize balanced three-phase no-load current, restrain triple harmonics and reduce operating noise.② Greatly reduced no-load loss and no-load current delivers remarkable energy-saving benefits.③ Main insulation is encapsulated with epoxy resin, enabling stable operation under complicated service conditions.④ Windings are integrally solidified via vacuum casting with low partial discharge, high mechanical strength and excellent short-circuit resistance.⑤ Thin resin insulation layer ensures outstanding heat dissipation and strong overload endurance.
