Dry-type transformer
After over 30 years of innovation, we have formed a full series of dry-type transformer product lines, including SC to SCBH19 iterative models, as well as new energy equipment such as 1,500V energy storage systems. Prefabricated substation
Prefabricated substations are fully functional, reliable, with low investment, small footprint, and easy installation; they have good safety and a wide range of enclosure types. Pad-mounted transformers
In 1999, the company was the first in China to introduce the complete set of the most advanced design, process and manufacturing technology from GE in the United States, and successfully developed pad-mounted transformers with a compact structure and small size. Liquid-immersed transformers
Liquid-immersed transformers utilize a highly stable insulating liquid medium, and achieve efficient power transmission through electromagnetic induction between the iron core and windings. Reactors
Since the early 1990s, relying on the “Guangdong Provincial Urban Network Electrical Equipment Engineering Technology Development Center”, SUNTEN has developed and researched resin-insulated dry-type air-core reactors and dry-type iron core reactors. Grounding systems
In the late 1990s, SUNTEN developed an automatic tuning arc suppression coil grounding complete set that integrates primary high-voltage equipment and secondary control equipment. Switchgears
Since 2002, SUNTEN has been producing complete switchgear sets, with products covering the full range of 400V-40.5kV/400A-6300A, and having authorized cabinet models of Schneider MVnex+BlokSeT and ABB MDmax. Energy storage
SUNTEN (founded in 1988) is a leading enterprise in the field of power transmission and distribution, as well as new energy equipment, with core technologies in areas such as thermal power frequency regulation energy storage, wind-solar-storage integration, and industrial and commercial energy storage. -
