Key features

Hermetic Sealing Design: Oil-immersed type with sealed tank prevents air contact, improving oxidation resistance and delaying aging.

High Efficiency Core: Uses high-quality cold-rolled grain-oriented silicon steel to reduce no-load losses and current.

Low Maintenance Cost: Hermetically sealed design eliminates the need for oil replacement during normal operation.

Strong Short-Circuit Resistance: Coils wound with high-intensity enameled conductors ensure good ampere-turn balance and insulation.

Compliant with Standards: Meets IEC60076, GB1094, GB/T6451, and GB/T25289-2010 standards for power transformers.

Vacuum Processing: Vacuum drying and oil-filling processes ensure extremely low internal moisture levels.

Corrugated Tank Design: Fins swell and shrink with oil temperature changes, maintaining pressure and increasing reliability.

30 Years Experience: Manufacturer with over 30 years of experience in the power industry and global service network.

AI-Powered supplier vetting

SummaryThe supplier presents itself as an electrical equipment provider serving international power boards, contractors, factories, and power projects. It offers equipment supply, installation, commissioning, after-sales service, electrical solution design, OEM, ODM, and multiple forms of customization. Reported production capacity covers power transformers, circuit breakers, disconnectors, furnaces, and transformers, while exports account for 51%–70% of total sales. The supplier lists numerous management-system certifications and has 50 years of combined R&D engineer experience and 31–40 quality-control staff. However, the evidence also shows limitations: no overseas warehouses, showrooms, agents, branches, or offline trade-show participation; no new products reported in the past year; no available SDK; and weaknesses in documented quality, complaint-handling, supplier-service assessment, corrective-action, traceability, and fire-drill procedures. Financial data is present only as year labels, so financial...
