1.1 Ihe ndabere oru ngo

Enyere 1500 kVA pad mounted transformer na America na 2024. Ike nke transformer bụ 1500 kVA na ONAN jụrụ oyi. Isi voltaji bụ 22.86kV na ± 2 * 2.5% tapping range (NLTC), nke abụọ voltaji bụ 0.208kV, ha guzobere a vector otu YNyn0, na ọ bụ a akaghị nri na nwụrụ anwụ n'ihu transformer.

Our three-phase pad-mounted transformers are engineered to address critical grid challenges in demanding environments like the U.S. Gulf Coast, where units must withstand Category 4 hurricane winds and salt-rich atmospheres while fitting within 2.5-meter urban footprints. Constructed with 304 stainless steel tanks, hybrid foil-wire windings, and IP68 sealing, these transformers achieve >Ịrụ ọrụ 99%, belata mfu ibu site na 20%, ma na-ebuga ọkwa nkwụsịtụ n'okpuru 5 pC.
