500 kVA 11kV\/0.4kV Oil-Filled Electrical Distribution Transformer \u2013 Factory Direct Supply<\/strong><\/h2>\n

The 500 kVA electrical distribution transformer<\/a> (oil-filled, 3-phase) is engineered to deliver dependable voltage conversion in commercial, industrial, and public utility environments across North America and Europe. Rated at 500 kVA, this medium voltage transformer supports reliable 11kV to 0.4kV step-down operation, ideal for low-voltage load centers in municipal grids, logistics parks, residential substations, and manufacturing plants.<\/p>\n

The unit features a robust Delta-connected 11kV primary winding and grounded Wye 0.4kV secondary output. Custom voltage configurations\u2014such as 10.5kV\/415V or 12kV\/400V\u2014can be provided to meet local distribution code requirements across the United States, UK, Canada, Germany, and France. The core utilizes cold-rolled grain-oriented silicon steel for minimized core losses, while high-conductivity copper windings ensure low-temperature rise and optimized short-circuit resistance.<\/p>\n

Encased in a weatherproof, hermetically sealed steel tank, the 500 kVA oil-immersed transformer is filled with degassed mineral insulating oil and designed for indoor and outdoor installation. The standard ONAN cooling system supports quiet, maintenance-friendly thermal management, with optional radiator extensions available for high ambient environments.<\/p>\n

In 2023, multiple units of this 500 kVA distribution transformer were installed in a Canadian school district to modernize outdated utility substations. With smart load balancing and consistent voltage regulation during peak winter demand, they've demonstrated stable performance and improved energy efficiency under IEC and ANSI operating conditions.<\/p>\n

All Energy Transformer<\/a> products comply with IEC 60076, ANSI C57, CSA C2.1, and EN 50588 standards. Each 500 kVA medium voltage transformer undergoes routine testing including vector group confirmation, impulse withstand, temperature rise, and insulation resistance\u2014ensuring long-term grid reliability and safety.<\/p>\n

OEM and ODM options are available, supporting tailored branding and bulk transformer manufacturing for global EPC contractors and regional power suppliers. Energy Transformer serves core markets including the USA, Canada, UK, Germany, France, Netherlands, Spain, Italy, Portugal, and Australia.<\/p>\n

Whether powering new commercial developments, upgrading distribution infrastructure, or integrating clean energy into your grid, the 500 kVA electrical distribution transformer delivers the dependable quality and flexibility your project demands.<\/p>\n
