What Sets Mega Flexibles & Busbars Apart
At Mega Flexibles & Busbars (Pty) LTD, we’ve spent years supplying and engineering custom high-current power cables that perform where others fail — right in the heart of South Africa’s most demanding industrial environments, we partner with foundries and heavy industrial operations, knowing what it takes to keep their systems running safely and continuously under extreme conditions.
We design and build water-cooled power cables that withstand high current loads, intense radiant heat, and round-the-clock operation. In this article, we’ll explain what water-cooled power cables are, key components, the types of assemblies available, and why partnering with Mega Flexibles & Busbars makes all the difference.
Understanding What a Water-Cooled Cable Is
A water-cooled power cable is a specially designed high-current cable that uses circulating water to remove heat generated during operation. Unlike standard air-cooled cables, which rely on ambient airflow to dissipate heat, water-cooled cables actively transfer thermal energy away from the conductors, keeping the cable and surrounding equipment at safe temperatures.
These cables are essential in high-demand industrial environments, such as steel foundries, mining operations, and heavy manufacturing plants, where standard cables could overheat, degrade, or fail under continuous high-current loads. By circulating water through the cable’s design.
Key Components of Water-Cooled Power Cables
Each cable is a balance of electrical and thermal engineering.
- Conductor Core
- The core of the cable is typically manufactured from high-conductivity copper, allowing efficient power transfer while minimizing electrical losses under high current loads.
- Insulation System
- High-quality insulation materials provide electrical protection and resistance to heat, abrasion, and mechanical stress common in heavy-industrial environments.
- Water-Cooled Cable Terminals
- These terminals form the critical connection point between the cable and the furnace or power source. They are designed to manage both electrical current and heat, ensuring reliable performance during continuous operation.
- Water-Cooling Hoses
- Integrated hoses allow water to circulate through the cable assembly, effectively removing heat and preventing overheating or premature cable failure.
This design ensures safe, efficient, and long-lasting performance under the toughest conditions.
Applications of Water-Cooled Cables
- Induction Furnaces
- Induction furnaces are one of the primary applications for water-cooled power cables. These cables deliver high current to the induction coil, enabling efficient melting and refining of metals through electromagnetic heating. The induction coil generates a magnetic field that induces heat directly within the metal charge.
- Water-Cooled Cable Induction Systems
- In dedicated water-cooled cable induction furnace systems, these cables contribute to stable power delivery and controlled operating temperatures, supporting consistent furnace performance during continuous operation
- Steel Plants and Heavy Industry
- Beyond induction furnaces, water-cooled power cables are used throughout steel plants to supply high-power auxiliary systems operating under extreme heat, high electrical loads, and demanding industrial conditions
