Selection notes

How to read this family

20 kV distribution is used in industrial parks, mining, ports and utility networks where a higher medium voltage reduces line current and cable losses. The transformer must match both the 20 kV insulation level and the site's fault and load profile.

Fengguang supplies 20 kV oil-immersed transformers from 30 to 2,500 kVA in the S11, S13 and S20 families. Typical configurations include sealed tanks, ONAN cooling, off-circuit tapping and copper or aluminium windings. Low-loss and renewable-energy variants are available, and the design can be adapted for high ambient, dust, altitude or coastal corrosion.

For a 20 kV project, confirm the system grounding, insulation level, impulse withstand, tap range and cable termination before release. These inputs determine bushings, clearances and the protection scheme, not just the nameplate.

Buyer questions

Questions to settle before the datasheet

What is a 20 kV transformer used for?
It distributes power at 20 kV to industrial plants, mines, ports and utility substations, then steps down to 0.4 kV or another utilisation voltage. It can also step up renewable-energy collection circuits.
Can you match an existing 20 kV protection scheme?
Yes. Share the single-line diagram, relay settings and fault level. The transformer impedance, tap range and terminal arrangement can be checked against the scheme before the datasheet is approved.
Is a 20 kV unit available with low loss?
Yes. S13 and S20 designs are available with reduced no-load and load losses. The quotation should state the loss values and the efficiency class so that they can be compared on a total-cost basis.
How is the tank protected for outdoor use?
The standard tank is painted; for coastal or polluted sites a C4/C5 coating system, stainless fasteners, sealed cable boxes and an IP54 enclosure can be specified.
