02 Application engineering
Pole-mounted transformer solutions for overhead distribution networks and remote installations.
Transformation on overhead medium-voltage feeders and branches, installed on a pole or platform close to the load. Pole mounting removes the need for a substation building and suits the lines and clearances used by the network operator.
Workshops, small plants, telecom sites and roadside commercial supply connected to the overhead network. A pole-mounted unit provides a low-cost transformation point where a ground-level substation would be impractical or slow to permit.
Remote communities, islands, mine camps and project sites fed from a limited MV line. Compact, light pole-mounted units simplify transport and installation in locations with restricted access and limited lifting equipment.

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 Pole-Mounted Transformers when the main duties are Overhead distribution and Utility distribution feeders; compare Pad-Mounted Transformers when Underground distribution and Renewable and private networks 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 mounting arrangement, fuse and surge protection and CSP configuration. 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 Overhead distribution, Utility distribution feeders and Dispersed loads, 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 Pole-Mounted Transformers, also confirm site-specific environmental and installation engineering.
Provide at least Rated capacity, Primary voltage, Secondary voltage, Phases, the selected mounting arrangement / fuse and surge protection 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.
