Product Description

Product Description:

YT2500/33/0.4 is an efficient and reliable oil-immersed three-phase power transformer with a design capacity of 2500 kVA. It is designed to safely and stably step down the 33 kV high-voltage grid power to the 0.4 kV low-voltage distribution network. The transformer is made of high-quality silicon steel sheets and high-quality copper conductors, combined with advanced oil-immersed cooling technology to ensure low loss, high-efficiency operation and excellent heat dissipation performance. Its sturdy fully sealed oil tank structure effectively prevents oil aging and improves environmental adaptability. It is suitable for industrial and mining enterprises, commercial buildings and infrastructure as the core equipment of main distribution or regional distribution, meeting the stringent power supply needs. It is an economical and durable choice for high-voltage power conversion and distribution.
