Selection notes

How to read this family

10 kV is the most common medium-voltage distribution level in industrial parks, commercial developments and utility networks. A 10 kV distribution transformer steps that voltage down to 0.4 kV for the low-voltage board, or up for a renewable-energy collection circuit.

The Fengguang 10 kV range covers 30 to 2,500 kVA in S11, S13, S20 and S22 designs. Standard units use a sealed tank and ONAN cooling; low-loss and no-excitation variants are available for utilities and renewable projects. Copper and aluminium windings are both offered, with the choice driven by fault level, load profile and evaluated cost.

Selection normally starts with the maximum demand, simultaneity factor and allowed voltage drop, then checks transformer impedance against the fault level and protection settings. For outdoor sites, add the ambient temperature, altitude, pollution level and enclosure requirement. The final datasheet fixes losses, tap range, termination and finish.

Buyer questions

Questions to settle before the datasheet

How do I size a 10 kV distribution transformer?
Start from the maximum demand in kVA, not the sum of connected loads. Apply a realistic diversity factor, check the short-time overload and motor-starting voltage dip, then confirm the impedance and protection settings. A load study avoids buying a unit that is either over-sized or thermally limited.
What is the difference between S13 and S20?
Both are low-loss families, but they target different efficiency classes and loss evaluations. S13 is a widely used low-loss baseline; S20 is selected when a higher efficiency class or a lower total owning cost is required. The quotation should show no-load and load losses explicitly.
Can a 10 kV unit be used on a 20 kV network?
No. The insulation level, bushings and tap range are designed for the rated voltage class. A 20 kV project needs a 20 kV transformer. The same capacity may be available in both classes, but they are separate designs.
What protection and accessories are typical?
Typical accessories include a pressure-relief device, oil-level gauge, thermometer, drain valve, lifting lugs and a rating plate. Options include Buchholz relay, sudden-pressure relay, HV/LV cable boxes, surge arresters and an IP54 enclosure.
