Our 20kV distribution transformer is designed to step down medium-voltage power to a safe and usable low-voltage level for commercial, industrial, and utility applications. Built with high-efficiency magnetic cores and reliable insulation systems, it ensures stable power delivery, reduced energy loss, and long-term operational performance.

High-efficiency core design to minimize energy losses

Copper or aluminum windings available upon request

Robust insulation system for superior dielectric strength

Strong short-circuit withstand capability

Low noise and low partial discharge

Customizable voltage ratios and transformer ratings

Durable construction for harsh environmental conditions

Optional accessories: temperature controller, oil level gauge, pressure relief valve, cooling fans, etc.

Our model naming rule:

S–4000–13.2–0.4

Where:

S = SST Power

4000 = Rated capacity (kVA)

13.2 = High-voltage rating (kV)

0.4 = Low-voltage rating (kV)

Examples:

S–500–20–0.4 → 500 kVA, HV 20kV, LV 0.4kV

S–2000–11–0.4 → 2000 kVA, HV 11kV, LV 0.4kV

This 20kV distribution transformer is widely used in:

Industrial plants and manufacturing facilities

Commercial buildings and business districts

Residential power distribution networks

Utility substations and power infrastructure

Renewable energy systems (solar / wind step-down)

Infrastructure projects: airports, hospitals, schools, data centers, etc.
