Import 500kv Power Transformer — Buy in Bulk from Supplier in China

This 500kV power transformer is engineered with a shell-type tank and fully folded plate structure, designed to meet the latest national safety standards GB1094.1-2-1996, GB1094.3-2003, and GB1094.5-2008, as well as the International Electrotechnical Commission standard IEC-76. The core features chamfered joints and non-porous, non-stacked iron yoke technology, which minimizes core losses and electromagnetic noise while ensuring structural integrity during transportation.

The transformer body adopts multi-coil total assembly with constant drying measures to reduce coil rebound and ensure uniform contraction, significantly improving short-circuit withstand capability. Internal strengthening includes hard paper tubes between the core and coil to eliminate gaps, further enhancing mechanical strength. Standard industry practice for such units includes typical noise levels below 65 dB, typical efficiency ratings above 99 percent, and standard insulation classes such as Class A or Class F.

These units are primarily used in high-voltage transmission networks, substations, and industrial applications requiring reliable power distribution. Buyers typically include utility companies, large industrial facilities, and infrastructure developers. Trade terms for such equipment often involve FOB or CIF Incoterms, with fumigation wooden cases used for packaging to comply with international shipping standards. Verification of short-circuit withstand tests and partial discharge measurements is critical before deployment.
