6.6kV Three-phase Power Distribution Transformer Overview

This 6.6kV three-phase distribution transformer is a high-efficiency, low-loss power distribution equipment specially developed and customized for medium-voltage power grid systems and industrial power supply systems with 6.6kV voltage level. Adopting high-quality oriented silicon steel sheets and high-purity anaerobic copper windings as core raw materials, the transformer boasts excellent structural stability and electrical performance. It features low operating noise, extremely low no-load and load loss, as well as outstanding overload resistance and operational reliability.
The product supports two mainstream structural types: oil-immersed and dry-type, with a complete capacity range covering 50kVA to 25000kVA. Voltage ratios, dimensional parameters and technical specifications can be fully customized according to customer demands, perfectly adapting to diverse application scenarios including industrial factory power supply, urban and rural power grid distribution, commercial complex power supply and residential community power distribution projects.

6.6kV Three-phase Power Distribution Transformer Certification & Compliance Standards

International Standards: Fully compliant with IEC 60076 international power transformer core standards
Overseas Market Certifications: Equipped with CE, CB, EAC, KEMA and other authoritative overseas certifications, supporting smooth access to global mainstream markets
