Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of electrical power transformer in China. If you're going to wholesale durable electrical power transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.
An Electrical Power Transformer is essential equipment for transferring electrical energy between voltage levels in power generation, transmission and distribution systems. Zhejiang Hengli Electrical manufactures power transformers for utility projects, industrial facilities, substations, infrastructure and other medium- and high-voltage applications.
Unlike a transformer selected only by kVA rating, a complete project solution must consider voltage class, frequency, load characteristics, installation environment, impedance, cooling method and protection requirements. Zhejiang Hengli Electrical provides factory-direct OEM/ODM manufacturing, allowing customers to define the electrical and mechanical configuration according to project specifications and applicable standards.

Supply Scope
For B2B procurement, the supply scope can be configured according to the installation and commissioning requirements. A standard package may include the complete transformer unit, HV/LV bushings, nameplate, grounding terminals, lifting fittings, temperature indication and required connection accessories.
Depending on the project, Zhejiang Hengli Electrical can also supply items such as a conservator, oil level indicator, breather, pressure relief device, cooling equipment, tap changer and protection-related accessories. Technical drawings, product specifications, test documentation and other agreed documents can be prepared as part of the order.
Product Construction
The electrical power transformer is primarily composed of a magnetic core, HV and LV windings, insulation system, tank and cooling structure. The core is manufactured from electrical steel to help reduce no-load losses, while the windings are designed to withstand electrical, thermal and mechanical stresses during operation.
For oil-filled configurations, insulating oil performs two important functions: electrical insulation and heat transfer. The transformer tank provides mechanical protection and contains the insulating medium, while the cooling system removes heat generated during normal loading.
Component selection can be adjusted according to the rated capacity, voltage level and operating environment rather than using a one-size-fits-all configuration.
Key Features and Advantages
Project-specific customization
Voltage ratio, capacity, impedance, vector group, tap range, winding material and accessories can be specified for different grid and industrial applications.
01
Stable continuous operation
Carefully designed insulation, winding structure and thermal management help maintain reliable performance under normal operating conditions.
02
Practical installation configuration
Tank dimensions, connection arrangements, cooling equipment and accessories can be coordinated with the installation layout of the substation or plant.
03
Factory-direct communication
Buyers can communicate technical requirements directly with the manufacturer, reducing unnecessary communication layers between engineering, production and procurement teams.
04
Quality and documentation support
Manufacturing inspection and routine testing can be arranged according to the agreed technical specification, with corresponding technical documents supplied for project approval and delivery.
05
Applications
Electrical Power Transformers are commonly used in:
- Utility substations and distribution networks
- Industrial plants and manufacturing facilities
- Commercial and infrastructure projects
- Renewable energy and grid connection systems
- Mining and heavy electrical installations
- Residential and urban power networks
