In high-power electrical and electronic systems, effective thermal management is essential for maintaining performance and reliability. Water cooling cables combine power transmission with an integrated liquid-cooling system, allowing heat to be removed directly from the conductor. This innovation is transforming industries such as EV charging, data centers, welding, and high-frequency power transmission.
What Is a Water Cooling Cable?
A water cooling cable (also called a liquid-cooled cable) is a specially designed power cable that circulates cooling water through or around the conductor. By actively transferring heat away from the cable core, it maintains lower operating temperatures, reduces electrical resistance, and extends service life — even under continuous high-current loads.
Key Features
💧 Active Cooling System – Built-in channels allow constant water flow for efficient heat removal.
⚡ High Current Capacity – Supports large power loads in compact systems by maintaining stable temperature.
🔥 Excellent Thermal Performance – Operates safely under extreme environments or confined spaces.
🧱 Durable Construction – Uses corrosion-resistant copper conductors and flexible rubber or silicone insulation.
⚙️ Customizable Design – Available in various diameters, cooling configurations, and connection fittings.
Applications of Water Cooling Cables
Induction Heating & Welding Systems – Transfers high currents while cooling the electrode or torch.
Electric Vehicle (EV) Fast Chargers – Enables ultra-fast DC charging without overheating.
Data Centers & High-Performance Computing (HPC) – Supports efficient energy delivery in cooling-integrated environments.
High-Power Laser Equipment – Maintains stable power supply while preventing thermal damage.
Industrial Robots & Automation – Provides flexible, temperature-controlled cabling in motion systems.
