Pole-mounted transformers
Pole-mounted configurations for overhead distribution. Specify phase arrangement, mounting interfaces and the utility schedule before selecting a design.
Match the transformer to the network.
Key information for configuration review
- Phase (single or three) and rating
- Primary voltage and earthing system
- Quantity and delivery batches
- Utility specification and GTP schedule

| Rated power, reference | Single-phase 10 to 100 kVA; three-phase 25 to 315 kVA |
|---|---|
| Primary voltage | 11 kV or 33 kV (phase-to-phase or single-wire earth return to specification) |
| Secondary voltage | 240 V single-phase; 415/240 V three-phase |
| Tank | Hermetically sealed, with pole-mounting brackets |
| Bushings | Porcelain or polymeric, creepage to pollution class |
| Options | Surge arresters and fuse cut-outs mounted or loose; completely self-protected designs to specification |
Testing topics to confirm +
Confirm the applicable requirements, available reports and agreed test scope with the proposed manufacturer.
| Routine tests (every unit) | As IEC 60076-1: resistance, ratio, impedance and load loss, no-load loss, dielectric tests, leak test |
|---|---|
| Type tests (per design) | Temperature rise and lightning impulse; short-circuit withstand where specified |
