Key features

Low No-Load Loss: No-load loss is 30% lower than IEC standard for superior energy efficiency.

High Reliability: All in-service products have zero damages or oil leakage occurrences.

Advanced Core Design: Uses grain-oriented silicon sheets with 45-degree full-miter joints and epoxy resin pressing.

Low Noise Operation: Products 63MVA and below operate at noise levels lower than 58 dB (AN).

Superior Insulation: Apparent discharge amount is less than 80pC under 1.5 times rated voltage.

Robust Winding Structure: Interleaved-continuous HV coil with zigzag oil guide for optimal cooling and stability.

Enhanced Mechanical Strength: Corrugated oil tank wall without splicing reduces welds and increases strength.

Comprehensive Testing: Undergoes routine, type, and special tests including short circuit and temperature rise.

AI-Powered supplier vetting

SummaryThe supplier is presented primarily as a transformer manufacturer, with products covering power, dry-type, test, autotransformers, and multiple reactor types. Evidence indicates substantial production resources, including more than 10 production lines, 500 production and testing systems, reported annual capacity of about 18,000,000 kVA, and stated IEC-compliant performance. The supplier also reports CESI and KEMA test reports and experience exporting since 2004. However, the slices contain material inconsistencies: one record identifies the company as a manufacturer with 26 employees and a 2,000 m² plant, while another describes two production bases, over 1,000 employees, and a 370,000 m² factory. After-sales capability, customer cases, and specific innovation outputs are not sufficiently documented.

CertificationsThe supplier states that it holds CESI short-circuit and KEMA test reports for specified transformer ratings, and that product performance meets IEC standards. These are explicit testing and standards-related claims, but no broader certification list is provided.

R&D capabilityThe supplier reports four years of R&D engineer experience, an explicit focus on R&D, and imported production and testing equipment from Germany and Japan. These indicate some R&D and technology investment, but the slices do not document patents, new product development results, or other measurable innovation outcomes.

Production capacityProduction capability is supported by more than 10 production lines, 500 production and testing systems, a broad transformer and reactor portfolio, and a reported annual capacity of about 18,000,000 kVA. The records also describe advanced automated and vacuum-drying equipment, although the reported factory size and employee count conflict across slices.

Customization capabilityThe supplier states that it can completely meet customer requirements and offers a broad range of transformer, reactor, substation, heat-exchange, and pressure-vessel products. However, no specific examples of customized designs, engineering changes, or customer-specific projects are provided.

Client casesThe supplier states that it was appointed as a transformer manufacturer at 330 kV levels and below by the National Electric Power Corp and Mechanical Industry Union. This indicates institutional or industry recognition, but the slices do not provide named customer project references, delivery records, or detailed case studies.
