Voltnex Power is a China dry type transformer manufacturer and factory providing custom dry type transformer solutions for industrial, commercial, renewable energy, automation, and electrical distribution applications. Our dry type transformers are designed for projects requiring reliable voltage transformation, compact installation, low maintenance, and flexible configuration without the use of insulating oil.
With capacities from De 1 kVA à plus de 3 500 kVA, voltage options from 110V to 690V, and 50Hz or 60Hz operation, we manufacture transformers according to project requirements rather than offering only fixed standard models. Copper or aluminum windings, different insulation classes, cooling configurations, enclosure protection, terminals, mounting arrangements, and electrical parameters can be customized for OEM, ODM, engineering projects, distributors, and wholesale customers.
Whether you need a low-voltage dry type transformer for machinery, a three phase transformer for industrial distribution, or a customized transformer for a solar, automation, or power system, Voltnex Power can provide factory-direct manufacturing and engineering support.
Custom Dry Type Transformer Solutions
A dry type transformer is often selected when the installation requires a clean, oil-free and relatively low-maintenance transformer solution. Compared with oil-immersed equipment, dry type transformers can be used in many indoor electrical rooms, commercial buildings, factories, workshops, control systems, renewable energy installations, and other locations where oil containment is undesirable.
Voltnex Power fabrique single phase and three phase dry type transformers for different voltage conversion and isolation requirements. Depending on the application, the transformer can be configured as a step-down, step-up, or isolation transformer.
Typical requirements include 110V, 120V, 208V, 220V, 240V, 380V, 400V, 415V, 440V, 480V, 575V, 600V and 690V systems, with customized primary and secondary voltages available according to the project. Customers can also specify frequency, winding material, insulation level, enclosure, connection configuration and other technical requirements.
For projects requiring electrical isolation, Voltnex Power also provides transformateurs d'isolement à sec for industrial equipment, automation systems, UPS systems, solar applications, control panels and other sensitive electrical loads.

Dry Type Transformer Capacity and Technical Specifications
Our dry type transformer product range covers small control and equipment applications as well as larger industrial power distribution requirements. Standard and customized capacity options can be selected according to connected load, voltage requirements, starting characteristics, power factor and future expansion.
For industrial projects, transformer selection is not based on kVA capacity alone. The actual load, voltage difference, frequency, environmental conditions, installation method and required protection level should all be considered. Our engineering team can review your electrical specifications and recommend a suitable transformer configuration before production.
Applications for Industrial and Commercial Electrical Systems
Voltnex dry type transformers are manufactured for a broad range of electrical applications. In industrial facilities, they can be used for factory power distribution, machinery, CNC equipment, motor control systems, automation equipment, control panels and production lines. They can also be integrated into electrical systems supplying PLCs, relays, contactors, lighting circuits and auxiliary equipment.
For commercial installations, dry type transformers can be used in commercial buildings, offices, electrical rooms, data-related infrastructure, workshops and other low-voltage power distribution systems where compact and oil-free equipment is preferred.
The same manufacturing capability can be applied to renewable energy and modern electrical infrastructure. Dry type transformers can be configured for solar PV systems, battery energy storage systems, UPS systems, inverter systems and other power conversion applications, subject to the required voltage, capacity and electrical characteristics.
For distributors and electrical contractors, we can manufacture transformers with customized specifications and labeling requirements, making them suitable for project supply, replacement equipment and wholesale distribution.
China Factory Manufacturing, OEM & ODM
En tant que conséquence directe dry type transformer manufacturer in China, Voltnex Power supports OEM and ODM production for international customers. Instead of relying only on standard catalog configurations, we can manufacture according to customer drawings, electrical specifications, project requirements or existing transformer models.
Customization can include primary and secondary voltage, frequency, capacity, winding material, insulation class, enclosure protection, connection arrangement, cable entry, terminals, mounting dimensions and other mechanical or electrical requirements.
For OEM customers, we can also support customized nameplates, documentation and product configurations according to the requirements of the target market. This is particularly useful for electrical distributors, system integrators, engineering companies, equipment manufacturers and wholesalers that need a consistent factory supply.
Our production approach is designed for both individual project orders and repeat commercial requirements. Customers can provide their transformer specifications, single-line diagram, load information, existing nameplate data or application details, and our team can evaluate the appropriate configuration.
Quality Control and Testing
Reliable transformer performance depends on both electrical design and manufacturing quality. Voltnex Power applies production inspection and electrical testing procedures appropriate to the transformer configuration and customer requirements.
Testing and inspection can include winding and insulation checks, insulation resistance, dielectric withstand testing, ratio and connection verification, temperature-related inspection, visual inspection and other applicable quality checks.
Our dry type transformer designs are available according to IEC 60076 requirements, while specific project standards or testing requirements can be discussed before production. For export projects, technical documentation and product specifications can be prepared according to the customer’s purchasing and engineering requirements.
Wholesale Dry Type Transformers for Global Markets
Voltnex Power supplies dry type transformers to international customers across North America, South America, Europe, Asia, Africa and Australia, supporting distributors, contractors, engineering companies and industrial equipment buyers.
For customers in the USA, Canada, Mexico, Brazil, Chile, Colombia and other markets, voltage and frequency requirements can vary significantly. Therefore, we recommend confirming the complete electrical specification before ordering rather than selecting a transformer based only on capacity.
As a factory-direct supplier, we can provide customized transformer manufacturing, wholesale supply and project-based production. Our goal is to provide a practical combination of electrical specifications, manufacturing capability and competitive factory-direct supply for customers purchasing industrial power equipment from China.
