Company profile
Wantai was established in 1998, and after more than 20 years of development, it now has six subsidiary companies: Huainan Wantai Electric Co.,Ltd., Shanghai Wantai Digital Technology Software Co.,Ltd., Wantai Power Business Department, Anhui Wantai Geophysical Technology Co.,Ltd., Huainan Zaochen Electromechanical Technology Co.,Ltd., and Huainan Wantai Electric Hefei Branch.Wha's more, it has set up four major research and development bases in Huainan, Hefei, Shanghai, and Xi'an.
The subsidiary companies under Wantai have a wide range of product development fields, each with its own focus.Among them,Wantai Electric is committed to the construction of smart mines,mainly focusing on the construction of integrated communication networks for all mine automation, 5G+4G+WiFi6+UWB, and  intelligent transmission systems for permanent magnet motors, permanent    magnet rollers,frequency converters, and other terminal equipment. Huainan Zaochen mainly provides mining environmental protection solutions for water supply,  power, and dust reduction. Wantai Power Business Department focuses on the smart grid, providing unmanned, big data energy-saving remote operation and maintenance systems, and intelligent high and low voltage complete electrical equipment. Wantai Geophysics provides customers with an integrated security solution based on microseismic monitoring and warning. It's main technical   achievements include microseismic imaging,advanced detection during  excavation, as well as monitoring of mine gas, water hazards, mine tremors,slope stability, etc.  The products are suitable for fields such as mines,petroleum,tunnels,and urban safety.
With the rapid development of science and technology, embracing change from the inside out is a long-term established idea for us. Currently,Wantai's business model is based on the times. The changes have begun to shift,and a product line management  plan has been launched, embarking on the path of intensive business development. Meanwhile, Wantai accelerates the promotion of international strategic layout.
