Rated capacity: 30–4000 kVA · Primary voltage: 6 / 10 / 20 / 35 kV · Secondary voltage: 0.4 kV
02 Application engineering
Oil-immersed transformers for utility distribution and industrial supply in Kosovo: naturally cooled, outdoor-capable units for distribution substations and load centers (6 / 10 / 20 / 35 kV), applied in projects spanning industrial parks, renewable energy and mining under utility and EPC specifications.
Step-down transformation at distribution substations and pole-to-ground transformation points (6 / 10 / 20 / 35 kV), installed outdoors on the utility network. Natural-cooled oil-immersed construction keeps maintenance simple, and designs are aligned with the requirements of KOSTT / KEDS 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.
Supply to factories, processing plants and industrial estates (industrial parks, renewable energy and mining) from the medium-voltage grid. Oil-immersed units handle sustained and cyclic loads economically, and are normally installed outdoors in a fenced transformer yard next to the main LV switchgear.

HKXR POWER Technical Selection Guide
Guide for initial technical selection of distribution, power, dry-type, pole-mounted and pad-mounted transformers.07 Decision support
For Kosovo, 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 Industrial facilities, cooling, enclosure or insulation and protection should be reviewed during engineering rather than assuming one environmental class for the whole country.
Use KOSTT Electrical Equipment Code as the starting technical reference. Requirements from KOSTT / KEDS / ERO(ZRRE) should also be confirmed. 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.
