Industrial and Commercial Liquid-Cooled Energy Storage Systems

Dechun Electric adopts a modular design concept, innovatively integrating long-life battery cells, a high-efficiency balanced BMS (Battery Management System), a high-performance PCS (Power Conversion System), a thermal management system, an intelligent power distribution system, and an active safety system into a single independent outdoor cabinet to form an integrated, plug-and-play smart energy storage system. Each energy storage module is capable of energy storage and AC/DC power conversion, and is equipped with an intelligent liquid cooling system and a fire protection system, enabling safe, stable, reliable and long-term operation. Through parallel connection on the AC side, flexible capacity expansion of the energy storage power station is achieved.

SF6 gas-insulated, fully sealed, metal-enclosed switchgear

The SDC22-40.5SF6 fully insulated Jinxi-type switchgear is a completely sealed system, where all its live components and switches are enclosed in a stainless steel cabinet. The entire switchgear is not affected by external environmental conditions, thus ensuring reliable operation and personal safety, and achieving maintenance-free performance. By selecting expandable busbars, arbitrary module combinations can be realized. The expandable busbars are fully insulated and shielded, which guarantees high reliability and safety. At the same time, factory-based automated solutions can be provided to form the concept of intelligent switchgear, minimizing the workload of on-site installation and commissioning.
As a positive response to the wind power industry's pursuit of the thinnest and most flexible switchgear, this gas-insulated switchgear is specially designed to meet wind turbine manufacturers' requirements for wind power switchgear in terms of compactness, safety, flexibility, etc. It is widely used in onshore and offshore wind farms.

HDC15-12 Type Environmentally Friendly Gas-Insulated Fully Enclosed Ring Main Unit

It employs nitrogen (N₂) insulation, eliminating the use of SF₆ and any toxic byproducts generated by SF₆ arc‑extinguishing, thereby ensuring user safety. This approach supports green and environmentally friendly objectives by reducing greenhouse gas emissions. The enclosure is constructed from 304 stainless steel, offering excellent weldability and superior corrosion resistance. Automated laser welding ensures an ingress protection rating of up to IP67. The product's mechanism is designed to be waterproof, with all secondary components featuring sealed enclosures, effectively preventing condensation‑induced electrical damage and operational failures. An integrated industrial control board provides comprehensive equipment management, while an external HMI interface ensures operator safety and meets on‑site operational requirements.
