Portuguese Oil-Immersed Transformer Customer Visits GNEE Electric

Recently, a delegation of oil-immersed transformer customers from Portugal visited GNEE Electric, where in-depth exchanges were held on product selection, technical customization and project cooperation.

 

 

Accompanied by the company team, the customers went deep into the production line and visited the core cutting and processing area, winding workshop, final assembly line and testing center in sequence.

 

On-site engineers explained in detail the implementation of key technical aspects of oil-immersed transformers, including low-loss design, temperature rise control and insulation system optimization. The customers highly recognized GNEE's strict control over raw materials, standardized processes and full-process quality inspection system, confirming that the company is fully capable of serving the European market.

 

 

During the subsequent meeting room discussion, the Portuguese customers clearly put forward the core pain points in their actual projects:

• Large local grid fluctuations, requiring high short-circuit withstand capability of transformers
• Strict requirements for energy efficiency standards, demanding lower no-load and load losses
• Marine climate environment, with high demands for corrosion resistance and long-term stable operation
• Tight project schedule, requiring high delivery efficiency

 

In response to the above challenges, GNEE's technical team provided targeted solutions one by one:

• Enhancing short-circuit withstand capability by optimizing the winding structure design
• Reducing loss levels by adopting high-quality silicon steel sheets and advanced lamination technology
• Providing upgraded solutions for anti-corrosion coating and sealing structure to adapt to high-humidity environments
• Ensuring stable and fast delivery based on a mature supply chain system

 

 

GNEE Electric provides comprehensive customized services in accordance with different national standards and project requirements, including but not limited to:

 

• Customization of voltage levels and capacities (adaptable to multiple specifications such as 10kV/20kV/33kV)
• Optimized design for loss levels (meeting European standards and high energy efficiency requirements)
• Special environment-adapted design (for high temperature, high humidity, high salt spray and other scenarios)
• Customization of appearance structure and installation methods (compact type, outdoor type, etc.)
• Support for international certifications (supporting CE and other relevant certifications)

 

Through the integrated capabilities of "Technology + Manufacturing + Service", GNEE can quickly respond to customers' personalized demands and achieve true "project-based customization".

 

 

GNEE has always adhered to a customer problem-oriented philosophy, providing full-process solutions from initial project design to later operation support. During this negotiation, the two parties not only clarified technical details but also reached preliminary consensus on subsequent sample confirmation, bulk orders and long-term cooperation models.

 

 

This visit from Portuguese customers is not only a routine business exchange, but also a comprehensive test of GNEE Electric's customization and technical strength.

 

In the future, GNEE will continue to provide professional, efficient and reliable solutions to help global customers cope with complex power application scenarios and achieve win-win development.
