HONORS & QUALIFICATIONS
-
Golden Triangle Electric Power Technology Co., Ltd holds dozens of patents, including the invention patent for the "circular cross-section three-phase transformer core" (Patent No.: ZL99114346.0), which is applied to our three-dimensional triangular coil core transformers.In 2012, our products were included in the national Energy-Saving Project Promotion Catalog by the Ministry of Industry and Information Technology, the Ministry of Finance, and the National Development and Reform Commission. This made us the only power enterprise in Wenzhou to qualify for direct subsidies from the Ministry of Finance.In 2014, we were awarded the "Zhejiang Provincial First Major Technical Equipment" honor, marking a historic zero breakthrough in the Yueqing region that we have maintained for consecutive years.
PROFESSIONAL DESIGN & PRODUCTION TEAM
We have a team of over 200 employees, including more than 150 front-line production staff. With years of hands-on experience in transformer manufacturing, our production team masters every detail and key process step to ensure strict quality control at every stage. Our technical team, comprising over 50 senior engineers and professionals, is fully capable of designing and manufacturing transformers that meet all required performance and special technical indicators. We have also established an academician workstation and a postdoctoral innovation workstation in collaboration with experts and professors from leading electrical and power engineering universities.
