Descripton

ZGS installed substation is made of American box changed. The product as the cable of distribution network power supply unit, high voltage control, protection, substation, as well as the power distribution equipment in one of the sets of pre products, widely used in urban and rural distribution network.The product will be high voltage load switch, high voltage fuse in the transformer oil, with a total of two kinds of structural forms of the transformer box body or box. 
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. The product is divided into ring network, terminal type and power supply mode. In order to make this product is more suitable for the actual requirements of the power grid in China, company and push the plug type fuse, fuse fuse does not affect the performance of transformer oil. According to the low voltage feed to the complexity of the, ZBW-12/0.4 products points to strengthen the standard type, type and comprehensive type three shell form, users and design units in the selection. Do more flexible and more economic.

Product Features and Structure

• Application and Structure: The ZBW prefabricated substation, also known as an "American box-type substation," uses a fully sealed structure to ensure environmental resilience. The transformer section integrates a high-voltage load switch and high-voltage fuse in transformer oil, providing reliable protection without compromising transformer oil quality.
• High-Voltage Components: Equipped with a high-voltage load switch, high-voltage fuses, and connection options for both ring network and terminal configurations, the substation meets diverse distribution network requirements with flexibility and safety.
• Monitoring and Maintenance: The substation tank includes indicators for oil temperature, oil level, pressure, and pressure relief, ensuring effective monitoring of transformer status.
• Shell Construction: The robust shell is manufactured from high-strength materials with anti-corrosion treatment, providing protection against harsh weather. This makes the substation ideal for outdoor installation with long service life.

Technical Parameters

Technical Specifications

• Rated Voltage: 10/0.4 kV (high and low voltage sides)
• High-Voltage Side Rated Voltage: 10kV or 12kV
• Low-Voltage Side Rated Voltage: 0.4kV
