Daelim Transformer 300 kVA Power Transformer

Transformer Features

Transformer Features

The 300 kVA power transformer, features a primary voltage of three-phase 27,600V Delta and a secondary voltage of three-phase 480GrdY/277V. Equipped with a 5-position tap changer, its high and low voltage bushings are ingeniously side-mounted with an air terminal chamber, tailored in size to meet customer specifications. The positioning of bushings and phase rotation is carefully coordinated with primary and secondary switchgear to ensure precise alignment upon field connection.

Constructed with copper winding material, this transformer offers superior short-circuit resistance, ensuring heightened reliability, mechanical strength, and a compact size compared to aluminum counterparts. Featuring a three-legged core construction, it is air-cooled without the need for fans or additional mounting provisions.
