    2500kVA Three Phase Oil Immersed Transformer

    2500kVA oil-immersed three-phase power transformer is a three-phase oil-natural cooling main distribution transformer with a rated capacity of 2500 kVA. Mineral oil is adopted as insulation and cooling medium. The iron core is made of high-permeability cold-rolled silicon steel sheets, and the windings are wound with oxygen-free copper wires.

    The equipment features low operating loss and stable insulation performance. Compatible with the common voltage class of 10kV/0.4kV, it boasts strong overload tolerance and short-circuit withstand capability. Widely used in large-capacity power supply scenarios such as industrial plants, commercial complexes, municipal power distribution facilities and substations, it can operate continuously and stably for a long term with easy maintenance, suitable for installation in both indoor and outdoor power distribution rooms.

    Rated Capacity: 2500 kVA, three-phase AC power transformation

    Cooling Mode: ONAN (Oil Natural Air Natural)

    Conductive Material: All-copper windings with low loss and strong current-carrying capacity

    Insulating Medium: Special cooling and insulating transformer oil

    Protection Configuration: Gas relay protection, oil temperature monitoring, pressure relief, oil level indicator

    Application Scenarios: Centralized power distribution for large-capacity industrial, municipal and commercial projects
