Product Description

Summary:

According to the document spirit of State Grid and the development trend of distribution equipment at home and abroad, Yueqing Liyond Electric Co., Ltd  immediately established a research and development team to develop solid insulated ring main unit. Through two years of unremitting efforts, the company successfully completed the development of TSR-12 (I) series products in the second half of 2012, and passed the type test of the whole project; meanwhile, the company In order to more widely adapt to the different needs of this large market in China, the development of TSR-12 (II) series products and the type test of the whole project were completed in 2014. So as to lay a leading and leading position in the field of solid insulation industry.
