Full Specifications Water-Cooled Cable used for Submerged Arc Furnace
The water-cooled cable is a key component of the short network system in submerged arc furnaces (SAF). It is used to connect the secondary terminal of the transformer to the movable copper pipe (copper shoe) inside the furnace, transmitting large currents ranging from thousands to tens of thousands of amperes. As it operates under high temperature and strong electromagnetic fields for extended periods, and must bend and move with electrode lifting, it requires extremely high conductivity, flexibility, cooling effect, and sealing performance.
1. Definition
Water-cooled cable is a special type of cable with a hollow interior for water flow, used in high-current heating equipment. Commonly known as "water cable," it consists of three parts: electrode (cable head), flexible conductor, and outer hose.
2. Functions
2.1 Current transmission: Transmits high current from transformer secondary side to electrode copper shoe
2.2 Flexible connection: Accommodates movement requirements during electrode lifting and rotation
2.3 Cooling: Removes heat generated by conductors through internal circulating water
3. Working Environment
Withstands high current (thousands to tens of thousands of amperes), strong electromagnetic fields, high-temperature radiation, and frequent bending movement, requiring excellent sealing, pressure resistance, and flexibility.
4. Classification by Furnace Type
| Type | Features | Application |

| Electric Arc Furnace Water-Cooled Cable | Tin-plated electrode surface; lifting eyelets at ends for easy on-site installation; secured with two stainless steel clamps | Steelmaking electric arc furnaces |
| Electroslag Remelting Furnace Water-Cooled Cable | Electrode available in various configurations (flat flange type, bell mouth type, rotating electrode type); water inlet/outlet positions optional | Electroslag remelting furnaces |
| Medium Frequency Furnace Water-Cooled Cable | Flexible conductor uses enameled wire; no surface skin effect when transmitting medium frequency current, resulting in low heat generation | Medium frequency induction furnaces |
| Coaxial Water-Cooled Cable | Two water paths and two electrical paths in a coaxial structure; low leakage inductance, low power loss, energy saving >10% | Medium frequency and high frequency equipment |
