STD Distribution Transformers are individually designed and manufactured to meet the exact requirements of each application while exceeding industry standards. Built with liquid-oil immersion, these transformers offer high efficiency, excellent reliability, and long-term operational performance across a wide range of utility and industrial environments.

From small-scale installations at 25 kVA to large substations at 5,000 kVA, STD Distribution Transformers can be hermetically sealed or equipped with a conservator depending on the project’s needs. Each unit is tailored with special options and features integrated into the original design to meet specific operational requirements.

Windings are available in copper or aluminum, and transformers can be adapted for installation on complete transformer substations or steel-lattice poles. They are designed in full compliance with IEC 60076, EN 50464-1, ANSI, BSI, IEEE, NEMA, and TS EN60076, ensuring optimal performance, safety, and reliability.
