Portuguese Clients Visit GNEE ELECTRIC To Jointly Explore New Cooperation Opportunities For Oil-Immersed Transformers

Recently, a delegation of senior power equipment purchasers from Portugal visited the headquarters and production base of GNEE ELECTRIC, and held in-depth negotiations on product procurement of oil-immersed transformers, long-term strategic cooperation, and supply for overseas power supporting projects.

 

This visit is not only an on-site verification of GNEE ELECTRIC's product quality and production strength by the Portuguese merchants, but also lays a solid foundation for both parties to build a stable cross-border supply chain and further develop the European power market. It helps overseas customers solve difficulties in power equipment procurement and achieve efficient, stable and compliant power transmission and distribution.

Accompanied by GNEE ELECTRIC's foreign trade team and technical principals, the Portuguese delegation visited core areas including the standardized production workshop for oil-immersed transformers, iron core processing production line, coil winding workshop, finished product testing center, and warehousing and logistics zone.

 

On site, the staff explained in detail the production technology, quality inspection procedures and core technical advantages of three-phase oil-immersed power transformers, low-loss oil-immersed transformers and outdoor oil-immersed transformers, demonstrating the whole-process refined management from raw material selection, iron core lamination, coil insulation treatment, oil tank welding, oil injection and sealing to finished product withstand voltage test, loss detection and load test.

 

The delegation carefully inspected the production details, material selection and finished product appearance of oil-immersed transformers, and highly recognized GNEE ELECTRIC's strict production standards, complete quality inspection system and large-scale production capacity. They witnessed the company's professional strength in power equipment manufacturing on the spot, which further strengthened their confidence in cooperation between the two sides.

 

 

After the visit, the two sides moved to the negotiation meeting room for in-depth business communication.

 

 

During the negotiation, the Portuguese merchants frankly stated many pain points encountered in overseas procurement of oil-immersed transformers:

• Firstly, the European market has strict requirements on product energy efficiency and safety standards, and products from ordinary manufacturers are difficult to meet EU certifications and local grid access specifications;
• Secondly, long cross-border procurement cycles and difficult logistics control easily lead to delayed delivery and inadequate after-sales service; Thirdly, some products feature high loss and poor stability, failing to adapt to the long-term heavy-load operation demands of local industrial power consumption and municipal power supply;
• Fourthly, customized demands are hard to meet, with limited supply channels and long delivery cycles for non-standard voltage and capacity oil-immersed transformers.

 

In response to the pain points raised by the customers, GNEE ELECTRIC's team provided a one-stop customized solution:

1. Relying on years of experience in supplying power equipment overseas, we produce energy-saving oil-immersed transformers in strict accordance with EU standards and IEC international standards, and strictly control core indicators such as product loss, insulation performance, explosion-proof heat dissipation and weather resistance;
2. We build an exclusive cross-border supply chain system, strictly control production and delivery cycles, cooperate with professional overseas logistics channels to achieve on-time and efficient delivery, covering the whole process of customs clearance and distribution;
3. We are equipped with a professional technical team to provide one-stop services including model selection and calculation, customized design, installation guidance and after-sales maintenance, eliminating worries for overseas customers;
4. We support customization of parameters such as rated capacity, voltage level, connection group and appearance size to perfectly adapt to power consumption demands in different scenarios.

 

After the implementation of this solution, it will help customers realize low-energy consumption, high-stability and long-life power transmission and distribution, reduce later operation and maintenance costs and power loss, pass the inspection of local power departments smoothly, ensure the project is put into use as scheduled, and achieve cost reduction and efficiency improvement in cross-border procurement relying on long-term stable supply.

To further dispel customers' concerns, GNEE ELECTRIC's team shared a cooperation case of similar European customers: Previously, a Spanish power engineering company needed to purchase a batch of outdoor energy-saving oil-immersed transformers for the local municipal power grid renovation project, facing the same difficulties of strict standards, high customization demands and tight delivery schedule. GNEE ELECTRIC responded quickly to customer demands, provided tailored oil-immersed transformers adapted to the local power grid, strictly controlled production quality and delivery cycle, and provided full-process technical docking services.

 

The batch of products passed the inspection of the Spanish power department smoothly after arrival. Featuring low loss and stable operation, their trouble-free operation hours far exceeded industry standards, helping the customer efficiently complete the power grid renovation project and winning high praise from the employer. Subsequently, the two sides reached a long-term strategic cooperation, and GNEE ELECTRIC became the core power equipment supplier of the customer in Europe. This case fully verifies the product strength and overseas service capability of GNEE ELECTRIC's oil-immersed transformers.

 

 

At the end of the negotiation, the two sides reached preliminary cooperation intentions on the first batch of purchase orders for oil-immersed transformers, long-term supply agreements, technical docking, logistics and after-sales services. GNEE ELECTRIC's team presented corporate souvenirs to the Portuguese merchants, and both sides took a group photo to mark this friendly negotiation moment.

 

 

This visit and negotiation by Portuguese customers is not only another important breakthrough in GNEE ELECTRIC's overseas market layout, but also highlights the company's core competitiveness in the R&D, production and foreign trade services of oil-immersed transformers.

 

In the future, GNEE ELECTRIC will continue to focus on the power equipment manufacturing field, constantly optimize product quality and overseas service system, help more overseas customers solve power equipment procurement problems, and join hands with global merchants to build a new efficient, stable and green power transmission and distribution ecosystem, opening a new chapter of win-win cross-border cooperation.
