01 Technical data
10 kV-class models: 30–2500 kVA; 20 kV-class models: 50–2500 kVA; 35 kV-class models: 50–3500 kVA. Rated secondary voltage: 0.4 kV.
02 Application engineering
Dry-type transformer solutions for indoor and application-specific electrical systems.
Traction auxiliaries, station services, tunnels, airports and ports where space is limited and oil-filled equipment is restricted. Compact dry-type units can be installed in underground or enclosed electrical rooms, with fire-behaviour and ventilation requirements set by the project.
Auxiliary and local-distribution transformers for solar, wind and storage sites, and for plants that prefer oil-free equipment inside buildings or inverter stations. Dry-type construction suits enclosed installation, with cooling and protection confirmed to the site climate.
Indoor power distribution for data centers and facilities with continuous-supply requirements. Oil-free construction avoids part of the fire-protection and maintenance restrictions of oil-filled units, while loading, ventilation and enclosure options are configured to the project load profile.

HKXR POWER Technical Selection Guide
Guide for initial technical selection of distribution, power, dry-type, pole-mounted and pad-mounted transformers.07 Decision support
Choose Dry-Type Transformers when the main duties are Indoor substations and Commercial buildings; compare Oil-Immersed Transformers when Utility distribution networks and Distribution substations 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 AN/AF cooling, temperature monitoring and enclosure and protection. 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 Indoor substations, Commercial buildings and Metro and transport facilities, 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 Dry-Type Transformers, also confirm site-specific environmental and installation engineering.
Provide at least Rated capacity, Primary voltage, Secondary voltage, Phases, the selected AN/AF cooling / temperature monitoring 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.
