Built Around HAGOE's DC Power Equipment Manufacturing Experience
HAGOE Electric Technology Co., Ltd. was established in 2008 in Wenzhou, China, with manufacturing experience covering DC power supply cabinets, AC/DC integrated power systems, UPS systems, switchgear, substations and low-voltage electrical assemblies.
For GZDW projects, manufacturing involves more than cabinet assembly. The charging modules, monitoring components, protection devices, internal wiring and DC distribution sections need to work as one coordinated system.
Production quality control covers key stages including:
Cabinet fabrication and finishing — Sheet-metal processing, enclosure assembly and surface treatment are completed according to the approved cabinet drawings.
Electrical assembly — Busbars, charging modules, monitoring units, protection components and terminals are installed according to the approved electrical configuration.
Wiring verification — Internal wiring, terminal identification and circuit connections are checked against the approved drawings before testing.
Functional inspection — Charging functions, monitoring interfaces, alarm signals, communication interfaces and relevant switching functions are verified according to the project requirements.
HAGOE operates under ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018 certified management systems. The certified manufacturing scope covers DC power supply cabinets and other electrical power equipment, providing a documented quality-management basis for project production.
The GZDW series is primarily intended for applications where DC power must remain available for protection, control and auxiliary equipment.
The system can provide DC operating power for relay protection, circuit breaker operation, automation equipment, signaling and other secondary systems. 110V and 220V DC configurations cover common substation DC voltage requirements.
Factories, mines, metallurgy facilities, chemical plants and other industrial sites can use the GZDW system as a dedicated DC supply for control and protection circuits.
Rail transit and other infrastructure projects can require centralized DC power for control, signaling and communication-related equipment. The modular monitoring architecture allows the system to be configured according to project requirements.
For applications using lower-voltage DC systems, HAGOE can develop corresponding configurations such as 48V DC charger cabinets, subject to the required battery and charging specifications.
The final application configuration depends on the DC load, battery autonomy requirement, charging capacity and project protection scheme.
Choosing a GZDW supplier is not only about obtaining a cabinet with the correct voltage label. For an engineered DC power system, the supplier needs to understand the relationship between the charger, battery, DC distribution, monitoring and site application.
HAGOE has been manufacturing power supply and electrical equipment for nearly two decades, with its product scope covering DC power systems and related electrical equipment.
The GZDW platform can be configured for lead-acid, lithium or Ni-Cd battery systems according to project requirements.
Charging modules, battery capacity, feeder circuits, monitoring modules, communication interfaces and cabinet dimensions can be specified according to the customer's electrical design.
The HG-E5 and HG-E6 monitoring systems provide an integrated interface for system supervision, historical records and communication.
HAGOE can work from customer SLDs, load lists and technical specifications to prepare customized configurations and documentation for project procurement.
HAGOE operates under ISO 9001, ISO 14001 and ISO 45001 certified management systems, supporting controlled manufacturing and documented quality procedures.
