Product Overview
ZGS1-12/0.4 combined type transformer plays main role in urban and rural power supply .The product is divided into ring network type, terminal type and dual power supply type. In order to make the product more suitable for the actual requirements of China's power grid, a plug-in fuse is introduced. Fuse fault does not affect the performance of the transformer. According to the complexity of low-voltage feed out requirements, ZGS1 series products are divided into three shell forms: standard type, reinforced type and comprehensive type, for customers and designer selction.
