    Workersbee G4.0 GB/T Liquid-Cooled DC Charging Cable Dimensions

     

    The cable supports water-glycol or silicone oil cooling, with a typical coolant flow range of 1.5–3 L/min and coolant pressure of about 3.5–8 bar. The 400A version uses a 26.5mm TPU cable, while the 600A version uses a 30.0mm TPU cable, allowing charger manufacturers to select the right configuration based on current demand, cable handling, and installation requirements.

     

     

    With IP55 protection, UL94 V-0 flame rating, 3500VAC dielectric strength, insulation resistance above 500MΩ, and more than 10,000 mating cycles, this GB/T liquid-cooled charging cable is suitable for public fast charging stations, fleet depots, electric bus charging, logistics vehicles, and other high-use DC charging applications where thermal control and daily operating reliability are important.

    What certifications are available for this GB/T liquid-cooled DC charging cable?
    CQC, CE, and temperature-rise test documents are available for project review. Before order confirmation, we recommend checking the required market, current rating, cable configuration, and applicable document scope to ensure the documents match your project requirements.
    How should I choose between the 400A and 600A versions?
    The 400A version is suitable for GB/T DC fast charging systems where high current output, cable handling, and installation flexibility need to be balanced. The 600A version is designed for projects with higher current demand and stronger cooling requirements. The final selection should be based on charger output, cable length, charging duration, cooling system capacity, and site operating conditions.
    What cooling system is required for this liquid-cooled GB/T DC charging cable?
    The cable supports water-glycol or silicone oil cooling. The typical coolant flow range is 1.5–3 L/min, with coolant pressure of about 3.5–8 bar. The cooling system should be matched with the selected current rating, cable length, cabinet design, charging load, and ambient temperature.

     

    Has this GB/T liquid-cooled charging cable been tested for temperature rise?
    Yes. The cable has been tested at DC500A and DC600A under 40°C and 50°C ambient temperature conditions. The test requirement was terminal temperature rise ≤50K, and the result was qualified under the defined test conditions.

     


    What is the difference between a liquid-cooled and naturally cooled GB/T DC charging cable?
    A naturally cooled GB/T DC charging cable mainly relies on conductor size, connector structure, and air dissipation to manage heat. A liquid-cooled cable uses circulating coolant to help remove heat during high-current charging. It is more suitable for higher current output, longer charging sessions, and frequent-use DC fast charging applications.
    What information should be confirmed before ordering or integration?
    Please confirm the required current rating, cable length, cooling medium, coolant flow rate, coolant pressure, charger output voltage and current range, installation environment, certification requirements, connector color, and any project-specific marking or wiring requirements. These details help match the cable with the charging system and reduce integration risks.
