About VOBO

Xinjiang Qiangshi New Material Technology Co., Ltd. (VOBO), formerly a wholly-owned subsidiary of Hunan Wujiang Holding Group—a top 500 private enterprise in China—has focused on glass material R&D and production since its establishment in 2001. It later formally transitioned into a high-tech enterprise specializing in new materials for the power sector, dedicated to the R&D, production, and global sales of tempered glass insulators for power systems.

The company has invested 150 million yuan to establish two fully automated intelligent production lines for tempered glass insulators, achieving an annual production capacity of 7 million units. These lines cover the full range of models from 40kN to 850kN, suitable for all voltage levels of AC transmission lines from 10kV to 1100kV and DC transmission lines from ±500kV to ±1100kV, fully meeting the demands of transmission lines across all voltage grades.

The company maintains a high-level laboratory and high-voltage testing center equipped with dozens of precision testing instruments, establishing a comprehensive, multi-dimensional quality control system. The company holds internationally recognized QES certifications including ISO9001, ISO45001, and ISO14001, along with multiple system certifications for green power, green factory services, green supply chain management, and energy management. It has been awarded the AAA Credit Rating Certificate. All products undergo specialized testing by the China Electric Power Research Institute (CEPRI), ensuring standardized management for exceptional quality that has earned widespread recognition from domestic and international clients.
