Products Description

ZGSQ-12/0.4 pre-installed substation is a domestic American box transformer. As an important power supply unit in the wireline distribution network, the product is a complete set of pre-installed products, which integrates high-voltage control, protection, power transformation and distribution equipment, and is widely used in urban and rural distribution networks. The product places the high voltage load switch and high voltage flame breaker in the transformer oil, and has two structure forms: sharing box with the transformer body or separating the box. The oil tank adopts fully sealed structure, equipped with oil temperature gauge, oil level gauge, pressure gauge, pressure release valve, oil discharge valve and other components to monitor the transformer operation condition. The product is divided into ring network type, terminal type and power supply type power supply square.In order to make this product more suitable for the actual requirements of the power grid of various countries, the company has pushed the plug-type dry fuse, fuse fuse does not affect the performance of transformer oil. According to the complexity of low pressure feedout requirements, ZGSQ-12/0.4 products are divided into three shell forms: standard type, enhanced type and integrated type, so that users and design units can be more flexible and more economical in the selection.
