ZSG rectifier transformers are widely suited to electroplating, electrolysis, battery charging, DC drives, DC traction, excitation systems, electrochemical processing, metallurgy and industrial DC power supplies<\/strong>. Capacity, voltage, winding configuration, connection group and mechanical construction can be customized according to your equipment and project requirements.<\/p>\n Factory Direct | Custom Design | OEM & ODM | Global Industrial Supply<\/strong><\/p>\n A rectifier transformer must be designed around the complete power-conversion system rather than only the transformer rating. The primary voltage, secondary voltage, current, rectifier type, pulse configuration, impedance, cooling and operating duty all affect the final transformer design.<\/p>\n The ZSG series provides the AC supply required by the rectifier while allowing the transformer and rectifier system to be engineered together.<\/p>\n AC Grid \u2192 ZSG Rectifier Transformer \u2192 Rectifier \u2192 DC Power \u2192 Industrial Load<\/strong><\/p>\n This makes the transformer suitable for applications requiring stable, high-current or specialized DC power<\/strong>, particularly where conventional distribution transformers are not optimized for rectifier loads.<\/p>\n The ZSG series uses a dry-type construction with air cooling and an oil-free insulation system, making it suitable for many industrial and indoor electrical installations.<\/p>\n The transformer can be engineered for low-voltage, high-current secondary applications commonly found in electroplating, electrolysis, battery charging and DC industrial equipment<\/strong>.<\/p>\n Primary and secondary voltages, rated current, capacity, connection group and phase configuration can be customized to match the connected rectifier.<\/p>\n Winding conductors can be selected according to current, thermal performance, electrical requirements and customer specifications. Copper is particularly suitable for compact and high-current designs.<\/p>\n Where required, the transformer can be designed for different rectifier configurations, including 6-pulse, 12-pulse and other customized multi-pulse systems<\/strong>, depending on the rectifier architecture.<\/p>\n Voltnex Power provides customized rectifier transformer, dry type transformer and industrial power transformer<\/strong> solutions for equipment manufacturers, distributors, system integrators and industrial projects.<\/p>\n <\/p>\n Final electrical parameters are confirmed according to the customer’s rectifier system, load requirements and approved technical specification.<\/strong><\/p>\n The performance and service reliability of a rectifier transformer depend on the complete combination of its magnetic core, windings, insulation and mechanical structure<\/strong>.<\/p>\n Voltnex Power uses electrical silicon steel for the magnetic core and can provide copper or aluminum winding configurations according to the required current and thermal design. The insulation system is selected according to voltage level, operating temperature and application requirements.<\/p>\n For high-current rectifier applications, particular attention is given to conductor sizing, winding structure, thermal performance, insulation, mechanical strength and connection configuration<\/strong>.<\/p>\n The transformer can be supplied as an open structure or with a protective enclosure depending on the installation environment.<\/p>\n Every industrial transformer should be checked against its approved electrical and mechanical specification before shipment.<\/p>\n Depending on the project requirements, factory inspection can include:<\/p>\n For OEM and project orders, Voltnex Power can provide the agreed test reports, technical drawings and product documentation<\/strong>.<\/p>\n ZSG three phase rectifier transformers are designed for industrial applications where AC power must be supplied to a rectifier system for DC output.<\/p>\n Provides the transformer supply for rectifier systems used in metal plating and surface treatment processes where low-voltage, high-current DC power is required.<\/p>\n Suitable for industrial electrolysis and other electrochemical processes requiring dedicated DC power systems.<\/p>\n Can be integrated into industrial battery charging, battery testing and large DC charging systems according to the required voltage and current.<\/p>\n Suitable for rectifier-based DC drive systems, industrial motors and specialized DC traction power applications.<\/p>\n Can be customized for generator excitation, metallurgy, chemical processing and other industrial equipment requiring specialized DC power.<\/p>\n Rather than offering only fixed standard configurations, Voltnex Power can develop the transformer around your actual electrical system.<\/p>\n For a custom ZSG rectifier transformer, we normally need:<\/p>\n Input Voltage + Frequency + Required DC Voltage + DC Current + Application + Rectifier Type + Pulse Number + Quantity<\/strong><\/p>\n Additional information such as the electrical drawing, rectifier datasheet, equipment nameplate, installation environment and preferred winding material can help us provide a more accurate design and quotation.<\/p>\n Whether you need a small industrial rectifier transformer or a large high-current transformer<\/strong>, the final kVA rating and construction are determined from the complete system requirements.<\/p>\n An industrial equipment manufacturer required a three-phase dry-type transformer to supply a downstream rectifier for a high-current DC process.<\/p>\n The design was developed around the customer’s:<\/p>\n Voltnex Power selected the appropriate core, winding conductor, insulation system, cooling configuration and connection arrangement<\/strong> based on the complete system requirements.<\/p>\n The result was a customized transformer designed specifically for integration with the customer’s rectifier equipment rather than a standard distribution transformer.<\/p>\n Voltnex Power is a China-based industrial transformer manufacturer<\/strong> providing factory-direct solutions for international customers.<\/p>\n We support:<\/p>\n Custom Transformer Design<\/strong> OEM & ODM Manufacturing<\/strong> Factory Quality Control<\/strong> Flexible Configuration<\/strong> Global Supply<\/strong> A three phase rectifier transformer is a transformer designed to supply AC power to a rectifier system. It transforms the input voltage and electrical configuration before the rectifier converts the AC power into DC.<\/p>\n The transformer itself does not directly produce DC. It supplies the appropriate AC voltage and configuration to a downstream rectifier, which performs the AC-to-DC conversion.<\/p>\n ZSG transformers are commonly used for electroplating, electrolysis, battery charging, DC drives, DC traction, excitation and industrial DC power supplies<\/strong>.<\/p>\n Yes. Voltnex Power can customize capacity, primary and secondary voltage, current, winding material, connection group, pulse configuration, cooling, enclosure and other electrical and mechanical parameters.<\/p>\n Yes. The transformer can be engineered for high-current secondary applications based on the required AC input, DC output, rectifier configuration and operating duty.<\/p>\n Yes, where required by the rectifier system. Pulse and phase-shifting configurations should be confirmed from the customer’s rectifier design before production.<\/p>\n Copper and aluminum winding configurations can be considered according to the required electrical, thermal and mechanical performance.<\/p>\n Please provide the input voltage, frequency, required DC voltage, DC current, application, rectifier type, pulse configuration and quantity<\/strong>. A drawing or equipment datasheet is also helpful.<\/p>\n Looking for a three phase dry type rectifier transformer manufacturer<\/strong> for your industrial project?<\/p>\n Send us your transformer requirements or rectifier specifications.
