Overview

YBW series prefabricated box type substation

Product Details

summary:

The YBW series prefabricated substation is a compact and complete set of distribution equipment composed of high-voltage electrical equipment, transformers, low-voltage electrical equipment, etc., commonly known as European box transformers. It is used in high-rise buildings, urban and rural buildings, residential areas, high-tech development zones, small and medium-sized factories, mining and oil fields, and temporary construction sites for receiving and distributing electrical energy in the distribution system.
The YBW series prefabricated substations have the characteristics of strong completeness, small size, compact structure, safe and reliable operation, convenient maintenance, and mobility. Compared with conventional Shijian substations, box type substations of the same capacity usually occupy only 1/10 to 1/5 of the area of conventional substations, greatly reducing the design and construction workload and construction costs. In the distribution system, the product's technical performance meets GB/T17467-2010 "High Voltage/Low Voltage Prefabricated Substations",SD320－1992Technical Conditions for Box type Substations ", DL/T537-2002" Guidelines for Selection of High voltage and Low voltage Prefabricated Box type Substations ", IEC1330 standard. The shell material can be selected from non-metallic, composite board or steel plate according to user needs.
