Cast Resin Transformer

LS ELECTRIC Cast Resin Distribution Transformers use a continuous winding structure to deliver a compact design and high efficiency. The units are easy to maintain and offer durable performance against short-circuit mechanical stress, moisture, and flame spread. The dry-type transformers are suitable for applications with significant load variation, including railway power supply systems. These products can be customized to meet customer requirements, with voltage ratings up to 36 kV and capacities up to 25 MVA.

Rated Voltage: Up to 36 kV
Rated Power Capacity: Up to 30 MVA
Standard: IEC 60076-11, IEEE C57.12.01

Key Features

High Quality

Designed to withstand short-circuit events and provide high impulse-withstand voltage and overload capability.

High Reliability

Suitable for rapidly changing load conditions, with strong moisture resistance and flame-retardant performance.

Eco-Friendly

High-efficiency performance helps reduce carbon emissions, while the oil-free design reduces the risk of environmental contamination.

User Convenience

The oil-free design simplifies installation and maintenance.
