Key features

Fire-Proof Dry-Type Design: Uses epoxy resin cast process without oil, ensuring fire-proof, explosion-proof safety and long operation life.

Low Energy Consumption: Amorphous alloy core reduces no-load loss and current to 1/3 of silicon steel sheets for high efficiency.

Strong Corrosion Resistance: Amorphous alloy core fully wrapped by resin and silica gel to prevent corrosion and fragment falling off.

Low Noise Operation: Improved iron core and coil structure with special noise-reduction materials greatly reduces operation noise.

High Short-Circuit Resistance: Three-phase five-column structure with frame protection allows 150% rated load operation under air cooling.

Customizable Specifications: Customized rated capacity, voltage windings, connection groups, and frequency options available per customer needs.

ISO9001 & CCC Certified: Products certified with ISO9001 and CCC standards, ensuring quality and compliance for global markets.

Compact and Lightweight: Small volume, low weight, and easy installation design saves room and simplifies deployment.
