Introduction of 2500 KVA Three Phase Oil Filled Distribution Transformer
Primary Voltage:33KV 35KV
Secondary Voltage:0.38KV 0.4KV 0.415KV 0.44KV
Connection Type: Dyn11/Yyno or others
Standards: ANSI/IEEE CSA/CAN DOE
Power Rating: 2500 KVA
Certificate: CSA SGS CE UL cUL
In 2018, two 2500 KVA transformers were exported to Argentina in South America, with a rated capacity of 2500 KVA, a primary voltage of 20 KV, and a secondary voltage of 0.4 KV. These two transformers are used for local public utilities. The products have been specially customized, including enhanced insulation systems, additional cooling capacity, and seismic design to ensure long-term stable operation under the complex local climatic conditions and geological environment. The two transformers are currently operating normally, fulfilling Evernew Transformer's commitment to high quality and stable operation of transformers.
