# Jinlihua Electric: The expansion project for an annual production of 3 million ultra-high voltage glass insulators has been put into operation

According to the announcement from Jinlihua Electric (300069.SZ), its wholly-owned subsidiary Zhejiang Jinlihua Electric Equipment Co., Ltd. ("Jinlihua Equipment") plans to invest in the construction of a project to expand the production of ultra-high voltage glass insulators. The company will introduce two tempered glass forming production lines and supporting power supply and engineering auxiliary equipment from the German company Wöhler, resulting in an additional annual production capacity of 3 million ultra-high voltage tempered glass insulators.

The current project has been completed, with both production lines having finished equipment debugging and trial production, and they will officially commence production on March 31, 2025. After the project is put into operation, the company will add an annual production capacity of 3 million ultra-high voltage glass insulators.

The announcement stated that after the completion of the project investment and construction, the production capacity of the company's ultra-high voltage glass insulator products will be significantly enhanced, achieving an additional annual production capacity of 3 million ultra-high voltage tempered glass insulators on the basis of the original annual capacity of approximately 1 million pieces, effectively doubling the capacity. In the domestic ultra-high voltage glass insulator manufacturing field, the company's production equipment technology level is at an industry-leading position, and the company's capacity structure will be optimized. The increase in high value-added product capacity will enhance the company's profitability and average gross profit level
