02 Application engineering
Oil-immersed transformer solutions matched to distribution, industrial and infrastructure project requirements.
Step-down transformation at distribution substations and pole-to-ground transformation points, installed outdoors on the utility network. Natural-cooled oil-immersed construction keeps maintenance simple, and designs are aligned with the network operator’s technical requirements and the project EPC specification.
Supply to commercial centers, mixed-use developments and public buildings that are fed from a utility MV ring or radial feeder. Outdoor or ground-level substation placement keeps heat and noise away from occupied areas and can be coordinated with the local network connection rules.
Power distribution for mines, process facilities and remote operations where long feeders, high ambient temperatures and continuous duty are expected. Robust tank construction and natural cooling reduce dependence on auxiliary equipment; final accessories follow the site specification.

Choose Oil-Immersed Transformers when the main duties are Utility distribution networks and Distribution substations; compare Dry-Type Transformers when Indoor substations and Commercial buildings better match the site. Final selection depends on the installation environment, network topology, fire or oil-containment requirements, rating and project specification.
Key choices include tap changer, bushings and terminations and protection and accessories. Select them according to the load profile, connection arrangement, installation environment, protection philosophy and utility/EPC specification; items shown as options or project engineering are not automatic standard equipment.
Confirm ambient temperature, altitude, humidity, dust or corrosion exposure, indoor/outdoor location, ventilation, access and maintenance clearances. For applications such as Utility distribution networks, Distribution substations and Commercial and mixed-use developments, cooling, enclosure or insulation and protection should be reviewed during engineering rather than assuming one environmental class for every project.
Generic international market; standards and certification must be selected from the actual destination and project. Final losses, temperature rise, impedance, taps, accessories, tests and documentation must be checked against the applicable project specification; this page does not imply automatic approval by any authority.
Confirm the applicable routine tests, general arrangement drawings, electrical datasheet, accessory list and inspection/test documents before manufacturing. Type or special tests, witnessing and additional reports should be specified when the project requires them. For Oil-Immersed Transformers, also confirm site-specific environmental and installation engineering.
Provide at least Rated capacity, Primary voltage, Secondary voltage, Phases, the selected tap changer / bushings and terminations options, installation conditions and the applicable project or utility specification. If available, attach the SLD, datasheet or tender specification so the configuration can be reviewed before quotation.
