What Are 15kV–24kV Dry Type Transformers?

15kV–24kV dry type transformers are medium-voltage, cast resin transformers designed for safe and efficient power distribution in applications requiring higher voltage insulation levels. These transformers are commonly used in renewable energy systems (such as wind and solar farms), industrial facilities, and commercial infrastructure, as well as in projects requiring compliance with IEEE, CSA, or ANSI standards—especially for export to North and South American markets.

Encapsulated in epoxy resin, they are completely oil-free, flame-retardant, and self-extinguishing, making them ideal for fire-sensitive environments and indoor use.

Why Use 15kV–24kV Dry Type Transformers?

Fire Safety and Reliability

With epoxy-encapsulated windings, these transformers eliminate the risk of oil leakage or fire. Their flame-retardant design meets strict international safety codes, making them suitable for enclosed, public, or mission-critical installations.

Superior Moisture Resistance

The cast resin design protects windings from humidity, dust, and chemical corrosion—ensuring safe operation in coastal, underground, or high-altitude environments.

High Efficiency

Constructed with low-loss silicon steel cores and precision copper or aluminum windings, these transformers meet or exceed international standards for energy efficiency, including IEC 60076-11 and DOE 2016.

Key Features of 15kV–24kV Dry Type Transformers

Encapsulated Coil Technology:
Fully vacuum-cast resin windings ensure long service life, low partial discharge, and strong dielectric performance.

Cooling System:
Natural air-cooled (AN) by default, with optional air-forced (AF) systems for enhanced thermal management in compact installations.

Protection & Monitoring:
Equipped with thermal sensors (PT100 or digital), temperature relays, optional fans, and monitoring units for intelligent load management.

Quiet Operation:
Low noise levels (<60 dB) make them suitable for use in commercial, educational, and healthcare facilities.

Flexible Installation:
Available in IP23–IP44 enclosures for indoor and semi-outdoor environments; compact footprint allows for installation in tight electrical rooms.
