Water-Cooled Flexible Connector

Water-Cooled Flexible Connectors are critical components used in high current systems of Electric Arc Furnaces (EAF), Ladle Furnaces (LF), Submerged Arc Furnaces (SAF) and other metallurgical equipment.
The products combine the functions of flexible copper connectors and water-cooled expansion joints, providing reliable current transmission while compensating thermal expansion, vibration and mechanical movement generated during furnace operation.
They are widely used in secondary current systems between transformers, bus tubes, electrode arms, water-cooled cables and furnace conductive sections in steel plants and ferroalloy plants.
The water-cooled structure ensures efficient heat dissipation and stable operation under ultra-high current and continuous heavy-duty working conditions.
