YB27 pre installed substation is the domestic transformation of the American box transformer substation. Since the successful development of the development, speeding to build an American box changed, the product of the national market share of the first. As an important power supply unit in the cable distribution network, it is widely used in the urban and rural distribution network with high voltage control, protection, substation and power distribution equipment.

Product description

The product can be placed in transformer oil with a high voltage load switch and a high voltage fuse, and is provided with two kinds of structure forms of the common box or the box of the transformer body. Tank using full sealed structure, with the oil temperature gauge, oil level gauge, pressure gauge, pressure release valve, drain valve etc. element to monitoring transformer operation status. This product is divided into ring network type, terminal type and dual power supply mode. In order to make this product is more suitable for the actual requirements of the power grid in China, speeding electric and exit the plug type fuse and fuse fuse does not affect the performance of transformer. According to the complexity of the requirements of the low voltage fed, speed electric TB27 type products are divided into three types of standard type, enhanced and integrated type of shell, so that users and design units in the selection of more flexible and more economical.
