Our company is an entity that integrates the research and development, design, manufacturing, and 

sales of electrical connectors. The joint venture has been established for nearly 30 years. The main 

technology of our products is based on standards such as GB, IEC, MIL-5015, and VG95234. During 

research and design, not only we meet the technical requirements for electrical connectors in China's 

equipment manufacturing industry, but we also ensure that the product's installation dimensions, 

electrical performance parameters, and environmental durability are compatible and interchangeable 

with international similar connectors. The products include six major series of circular connectors and 

one series of rectangular heavy-duty connectors, with thousands of model specifications combinations, 

meeting the design and selection needs of electrical engineers. The products developed by our 

company have received technical patents, totaling as many as fifty. Currently, we have more than 

4,000 product combinations that have obtained TUV certification in Germany; over 1,000 specifications 

of the YD circular series have obtained UL certification in the United States.

We have obtained ISO9001 Quality Management System, ISO14001 Environmental Management 

System, and ISO45001 Occupational Health and Safety Management System certifications, and have 

maintained the honors of Shanghai High-Tech Enterprise and AAA Credit Enterprise for consecutive years.

Over the years, Hualun connectors have continuously provided electrical component support services for China’s transportation rail vehicles, construction machinery, power transmission and distribution 

equipment, thermoplastic machinery, industrial automation, and robot manufacturing enterprises.
