YWBWG Photovoltaic Grid-Connected Cabinet Series
This product is primarily designed for high-power commercial and industrial photovoltaic grid-connected systems ranging from 100 kW to 2,000 kW. It is installed between the grid-tied inverter (or AC combiner box) and the utility grid, offering a comprehensive suite of protection features, including anti-islanding protection, voltage-sensing auto-energization, undervoltage tripping, grid under-voltage and over-voltage detection, input surge protection, system overcurrent safeguarding, and grid isolation capabilities. Additionally, a multifunctional meter provides clear visibility into the system’s operational status through real-time display and fault-indication functions. The product has successfully passed industry-standard certifications such as CCC and ISO 9001 quality management system certification.
YWBWX Photovoltaic Grid-Connected Access Box Series
This product is primarily designed for residential photovoltaic distributed grid-connected power systems and small-scale commercial and industrial PV systems. It is installed in series between the grid-tied inverter and the utility grid, offering a comprehensive suite of protection features, including anti-islanding protection, voltage-sensing auto-reclosing, undervoltage tripping, overvoltage detection, lightning surge protection for inputs, system overcurrent safeguarding, and grid isolation—all essential for ensuring safe and efficient operation. Additionally, the product boasts precise energy measurement, reliable data transmission, and intelligent operational control, making it an indispensable component of home-based grid-connected PV systems. The product has successfully passed industry-standard certifications such as CCC and IS9001 for quality management systems.
YWGGD Low-Voltage Grid-Connection Cabinet Series
This product meets the technical requirements of relevant standards, including the National Standard "Code for Photovoltaic Power Generation Design," the "Technical Specifications for Grid Connection of Distributed Power Sources," and the "Low-Voltage Switchgear and Control Equipment." It is suitable for use in low-voltage switchgear (also known as low-voltage grid-connection cabinets) designed for distributed and ground-mounted photovoltaic power generation systems.
KYN□ Photovoltaic High-Voltage Grid-Connection Cabinet Series
This product complies with relevant national standards, including the "Code for Photovoltaic Power Generation Design," the "Technical Specifications for Distributed Generation Grid Connection," and the "Switchgear and Control Equipment from 3.6kV to 40.5kV," and is suitable for high-voltage-side switchyard equipment used in distributed and ground-mounted photovoltaic power generation systems (also known as high-voltage grid-connected complete switchgear cabinets).
6–35kV Prefabricated Enclosure Series
Offering a fully modular, prefabricated substation solution that reduces the footprint by 30% and shortens the system design, installation, and commissioning timeline by 70%. The solution features all-metal prefabricated cabins equipped with an intelligent environmental control system, making it suitable for challenging climate and geographic conditions such as high temperatures, high humidity, and dusty environments.
YB-40.5/0.69-4000 Photovoltaic On-site Step-Up Substation Series
YB-40.5/0.69-4000 Photovoltaic On-site Step-Up Substation—developed by our company as a series of products that build upon our previously manufactured 10kV and 35kV combined transformers. Drawing on advanced technologies both domestically and internationally, we’ve tailored these solutions to meet China’s specific needs. This innovative product integrates a transformer, load switch, and high-voltage fuse—all housed within the compact enclosure of a box-type substation. It leverages the transformer’s insulating oil as both the insulation medium and coolant for the entire unit, featuring a fully sealed design. The exterior is constructed in modular sections, undergoing processes such as shot blasting, acid cleaning, phosphating, and sequential application of primer, mid-coat, and topcoat. As a result, the surface boasts exceptional scratch resistance, weather durability, and UV protection—far surpassing the performance of conventional coatings. Additionally, this substation offers key advantages like compact size, lightweight construction, and ease of installation.
ZGS□-12 Photovoltaic/Wind Power Step-Up Transformer Series
The box-type substation structure is divided into six sections: the transformer body, high-voltage room, low-voltage room, monitoring room, switchgear operation room, and fuse room, which can be arranged in either an "H" shape or a "Y" shape.
YB□-500/1600 Photovoltaic European-Style Transformer Series
The YB□-500/1600 PV European-style packaged substation is widely used in photovoltaic power generation systems, as well as in urban grid upgrades, residential communities, high-rise buildings, industrial and mining facilities, hotels, shopping malls, airports, railways, oil fields, ports, highways, and temporary power supply installations—suitable for both indoor and outdoor applications.
