ZBG Series American Pad Mounted Combined Substation
Scope of Application
Urban Residential Distribution Networks
This product is widely used in urban communities with limited space, green belts, and roadway lighting projects.
Commercial and Public Facilities
It is also suitable for locations requiring compact layouts, such as shopping centers, hospitals, schools, airports, and rail transit stations.
Small-scale Wind and Solar Power Plants
It enables on-site voltage step-up and power supply for distributed rooftop solar PV and small wind turbine projects.
Industrial Park End-User Power Supply
It meets power distribution needs at the end-user level in factories, as well as requirements for temporary construction power and outdoor power supply in mining areas.
Product Description
-
1 - Compact Size: Featuring a compact structure and small footprint, the unit allows for convenient and flexible installation. It is suitable for both ring-main and terminal power supply configurations, enabling easy switching and effectively enhancing power supply reliability.
-
2 - High Safety Performance: It utilizes a fully insulated, fully sealed structure that is safe, reliable, and maintenance-free, ensuring personal safety. The high-voltage side employs dual-fuse protection: a dual-sensitive plug-in fuse (providing both thermal and overcurrent protection) and a current-limiting backup fuse, thereby reducing operating costs. High-voltage cable connections use a fully insulated, safe, and easy-to-operate connector design.
-
3 - Superior Manufacturing: Specialized vacuum drying and vacuum oil-filling processes are employed. The company applies manufacturing standards typically reserved for 110kV products to its 10kV units, ensuring high quality for the box-type substations.
-
4 - Excellent Performance: The transformer features a three-phase, five-limb core structure utilizing either a step-lap joint or wound-core process. It offers low noise and low loss, along with robust resistance to short circuits and overloads.
-
5 - Strong Environmental Adaptability: The enclosure is designed to meet specific operating environment requirements, utilizing anti-corrosion construction and specialized coating treatments. It offers "three-proof" capabilities (resistance to condensation, salt spray, and mold), meeting anti-corrosion standards for high-temperature and high-humidity environments.

Technical advantages
Our independently developed and manufactured ZBG series transformer features a compact design that significantly reduces overall dimensions compared to traditional European split-compartment models. It utilizes a stepped-lap amorphous alloy core to minimize no-load losses, thereby lowering operating costs. The unit is equipped with Bay-O-Net dual-sensing fuses and a pressure relief valve; the fuses effectively protect the transformer from burnout caused by abnormal loads (such as overcurrent or overheating), while the pressure relief valve prevents tank deformation resulting from rising internal pressure. The enclosure features a three-layer anti-rust and anti-corrosion coating, and an internal dehumidification device ensures reliable operation in coastal and high-humidity environments. Designed for convenience, the unit allows for single-sided front access, eliminating the need for clearance space around the sides and simplifying daily inspections and maintenance. This product is customizable, holds comprehensive international certifications, and meets the requirements of global power distribution export projects; please feel free to contact us for more information.
