Submerged Arc Furnace Water-Cooled Cable
High-Current Power Transmission by HANI Metallurgy
The Flexible Artery of High-Power Smelting
The Submerged Arc Furnace Water-Cooled Cable is a critical component of the high-current “short net” system, responsible for carrying massive electrical energy from the transformer to the electrode arms. As a specialized SAF cable, it must provide low electrical impedance, extreme flexibility to accommodate electrode movement, and exceptional thermal management. At HANI, we have developed advanced furnace power cable solutions using high-conductivity stranded copper and specialized outer protective sleeves. Our cooling cable designs utilize a high-flow water interior to dissipate the heat generated by electrical resistance and radiant furnace heat, ensuring that the power delivery remains stable even at currents exceeding 100 kA.
HANI’s Submerged Arc Furnace Water-Cooled Cable is engineered for maximum service life in the harsh environment of an EAF or SAF bay. Whether for silicon manganese or calcium carbide production, the SAF cable must withstand constant mechanical flexing and electromagnetic vibrations. Our furnace power cable features a non-magnetic stainless steel terminal design to eliminate eddy current losses and a high-purity rubber hose that is resistant to carbon dust and sparks. By utilizing our cooling cable technology, producers can achieve better power factors and a significantly lower risk of “cable blowout” accidents. As a leading manufacturer of high-current conductors, HANI provides Submerged Arc Furnace Water-Cooled Cable solutions that are essential for the safe and efficient operation of large-scale smelting furnaces.

The Physics of Skin Effect and Flexible Conduction
The performance of a Submerged Arc Furnace Water-Cooled Cable is determined by its ability to manage the “Skin Effect” characteristic of high-frequency AC currents. In an SAF cable, the current tends to flow on the surface of the copper strands. HANI’s furnace power cable utilizes a specialized “Hollow-Core” multi-strand geometry that maximizes the effective cross-sectional area while allowing cooling cable water to flow in direct contact with the inner strands.
Cable Engineering Principles:
1. Zero-Reactance Stranding: Ensures equal current distribution among all strands in the Submerged Arc Furnace Water-Cooled Cable.
2. High-Pressure Termination: Forged copper terminals are swaged onto the SAF cable to ensure the lowest contact resistance.
3. Electromagnetic Shielding: Prevents “chafing” damage caused by furnace power cable vibrations.
Scientific facts show that a 10°C increase in cable water temperature can reduce the copper conductivity by approx. 4%. HANI’s Submerged Arc Furnace Water-Cooled Cable ensures that your cooling cable operates at a high Reynolds number to maintain turbulent flow for maximum heat dissipation. Our SAF cable solutions also include protective outer sleeves made from Kevlar or high-temp silicone to prevent damage from molten metal splashes and slag.

Professional FAQ for SAF Water-Cooled Cables
Q1: How does the HANI cooling cable prevent internal scaling?
A: We recommend using demineralized water in the Submerged Arc Furnace Water-Cooled Cable circuit. Our SAF cable interior is also polished to maintain high water velocity, preventing the buildup of mineral deposits.
Q2: What is the benefit of a “Carbon-Free” outer hose in a furnace power cable?
A: Carbon-free hoses have very high electrical resistance. This prevents the Submerged Arc Furnace Water-Cooled Cable from “shorting out” against other cables or grounded steel structures in the cooling cable bay.
Q3: How often should the SAF cable terminals be inspected?
A: We recommend a monthly visual inspection and a semi-annual thermal scan of the furnace power cable terminals to ensure that there is no localized resistance heating in the Submerged Arc Furnace Water-Cooled Cable system.
