2500KVA 13.2kv-400v ONAF

Hermetically sealed Oil-immersed transformer with side-outlet bushings in protectivesteel boxes. The side-mounted bushing terminals are fully enclosed by insulated protective boxes, cables exit laterally from the enclosure. It adopts high-efficiency grain-oriented silicon steel core and full-copper winding.

The protective enclosure provides multiple-layer protection for bushing insulators and cable connection terminals: it blocks direct exposure to rain, dust, salt spray and UV sunlight, slows terminal corrosion and pollution flash over risk; prevents short-circuit faults triggered by birds, rodents, snakes and foreign objects; isolates live conductive parts to avoid accidental human contact, improving site operation safety. The enclosure is designed with cable side-exit openings, quick-open hinged structure for convenient inspection and maintenance; some versions are equipped with observation windows for checking connection status without removing the box.

This structure is preferred for outdoor installations, coastal salt-spray areas, heavy-pollution sites, locations with high safety requirements and wildlife-prone regions. With anti-corrosion & high-temperature resistant construction, the transformer can operate stably under harsh conditions.
