What's New

Let's take a look at the development process of box type substation together with the small series of box type substation:

Box type substation is applicable to residential quarters, urban public transformers, busy downtown, construction power supply, etc. users can select box type transformers according to different service conditions and load levels. Since its inception, box type substation has developed very rapidly, accounting for 70% of distribution transformers in developed countries in Europe and 90% in the United States. With the rapid development of China's urban modernization and the continuous renewal and transformation of urban distribution network, it will be widely used.

For the box type substation, since the late 1970s, China has introduced and imitated the box type substation from France, Germany and other countries. In terms of structure, it adopts the composition of high-voltage and low-voltage switchgear and transformer. This box type substation is called European box type substation, which is figuratively compared to building a house for high-voltage and low-voltage switchgear and transformer. Since the 1990s, China has introduced the American box type substation, simplified the structure of load switch, ring network switch and fuse, put them into the transformer oil tank and immersed in oil. Oil immersed zinc oxide arrester is also used as lightning arrester. The oil conservator is removed from the transformer, and the oil tank and radiator are exposed to the air. This kind of box transformer is called American box transformer, which is figuratively compared to hanging a box next to the transformer
