The dual-split epoxy resin cast dry-type transformer can be individually customized according to customer requirements. The high-voltage coil adopts a segmented structure with low interlayer voltage and low inter-segment field strength, providing strong overload capacity. The high-voltage coil is cast with resin using a fully static casting process, offering high mechanical strength, strong short-circuit resistance, and partial discharge levels superior to national standards. It features low losses, low noise, significant energy-saving effects, and is environmentally friendly with no pollution. It is suitable for operating environments with strict environmental requirements or special needs. The transformer is primarily used for factory equipment power supply, photovoltaic power generation, energy storage systems, and other fields.
