In the smart power segment, the Group leverages cooperation resources from Qingdao International Academician Port and maintains a strategic partnership with Qingdao Minswei Technology Co., Ltd. We explore the application of intelligent monitoring, IoT and power management technologies in industrial power systems.

Depending on system configuration, our intelligent monitoring platforms support remote monitoring, anomaly early warning and operation management of transmission, distribution and end-use electrical equipment. They help operators improve equipment condition management, cut O&M costs and raise power management efficiency. Available functions depend on project configuration and system deployment.

Manufacturing Capacity and Quality Management

Hengfengyou Electric Group delivers electrical products and supporting services for various projects through integrated manufacturing, technical R&D and ISO-aligned quality control.

We define product configuration, conduct technical communication and coordinate production based on customer technical specifications, project requirements and applicable standards of the target market. Equipped with production facilities, standardized quality workflows and product testing procedures, we ensure products meet agreed technical requirements.

For different products and projects, we can supply relevant technical documents, test records and quality certificates within the agreed supply scope. Special certifications (available upon customer request), test capabilities (including 500 kV power transformer testing), inspection items (in compliance with IEC standards) and declarations of conformity are subject to valid certificates, test reports and product technical documentation. On-time delivery rate: 98.3%; Early delivery rate: 97.6%.
