limn: This is a next general environment-friendly new product developed in Jul.2004 to meet the requirements of city modernized construction, improve energy saving and performance, ensure the reliability of transformer performance.
ZGS11 type combination transformer allow high voltage charge switch, high voltage fuse and transformer in a same oil tank. The high/low voltage cambinate are shunted together to construct an integrated part and realize high voltage protection, low voltage metric compensation and low noise. The performance level is S11. It’s a multifunctional environment-friendly high-performance transformer with the high/low voltage input and output lines as underground cable and the high voltage side input line connected with enclosed elbow cable plug-in, which features small size, light weight, small loss, good appearance and reliable security and performance.
The parameters of the product meet the requirements of GB1094.1～2-1996, GB1094.3-2003, GB1094.5-2003《Power Transformer》,JB/T10217-2000《Combination Transformer》, GB/T6451-1999《3-Phase oil-merged power transformer technical parameters and requirements》and JTB.710.316.1《ZGS11 series combination transformer technical conditions》，see following list for detailed parameters: Rated Capacity
