SCB11 Series 10kV Three Phase Dry-type Power Transformer

Product Overview

SCB11 Series Dry-Type Transformers, leveraging exceptional low-noise, low partial discharge, and low-loss performance, the SCB11 series stands as a reliable choice for modern power systems. Featuring a vacuum-pressure epoxy resin casting process, it achieves a fully sealed insulation structure for windings, effectively resisting environmental corrosion. The core utilizes high-permeability grain-oriented silicon steel sheets combined with stepped-lap technology to minimize hysteresis losses, while the windings employ high-purity oxygen-free copper conductors, precision-cast under vacuum to ensure stable and reliable electrical performance.
The thin-insulation multi-layer cylindrical winding design significantly enhances short-circuit withstand capability, complemented by an efficient vibration-damping and noise-reduction system for quiet operation.
With professional design, reliable performance, and comprehensive service, the SCB11 series provides robust support for diverse power applications.
