Product Description

SCB11-1000kVA 6.3/0.4kV epoxy resin dry type transformer is a high-efficiency, low-loss cast-resin indoor power distribution transformer tailored for 6.3kV medium-voltage power systems. Featuring F-class insulation, ultra-low partial discharge, fireproof, explosion-proof and maintenance-free performance, this 1000kVA dry transformer adopts vacuum epoxy casting technology and full copper windings. Fully compliant with IEC and GB standards, it is ideal for industrial workshops, mining power distribution, factory substations, indoor power rooms and commercial power supply projects with 6.3kV input voltage.

Adopting high-quality grain-oriented silicon steel core and optimized electromagnetic structure, the equipment effectively reduces no-load and load loss with stable power output. The integral cast rigid structure provides strong mechanical strength and outstanding short-circuit impact resistance, adapting to frequent load changes and complex industrial grid conditions. Equipped with natural air cooling (AN) and optional forced air cooling (AF), it features strong overload capacity and low operating noise. With F-class high-temperature insulation and IP20 protection grade, it is dust-proof, moisture-proof and anti-corrosion, requiring zero daily maintenance, serving as the most cost-effective and safe power distribution solution for 6.3kV industrial power supply systems.
