China Factory 300mm2 Spot Welding Secondary Water Cooled Kickless Cable High Stability

Kickless Cable (also known as Secondary Water-Cooled Cable) is a uniquely structured insulated conductor, specifically engineered for industrial equipment operating with low voltage and high current. It employs multi-strand soft copper wires as the core conductor, sheathed tightly by a special rubber water hose, forming an efficient annular cooling chamber between the conductor and the hose. Both ends of the cable are securely connected to copper terminals via welding, reinforced and sealed with steel ferrules. Internal water ports within the terminals ensure unimpeded coolant circulation. This design enables the cable to carry extremely high operating currents while maintaining an exceptionally small cross-section, coupled with superior heat dissipation via internal water cooling. Its outstanding flexibility and mobility make it a critical flexible link component in automated welders, medium-frequency furnaces, and similar equipment, effectively balancing high-efficiency power transmission with reliable thermal management.

• High-Quality & Durable Rubber Jacket: The outer sheath is made of special synthetic rubber with excellent oil resistance, high-temperature tolerance, and anti-aging properties. It ensures durable and stable performance in harsh industrial environments, providing reliable protection.

• Reinforced & Thickened Conductive Structure: The cable features a precisely dimensioned and thickened copper core design. The ample conductor cross-section effectively reduces current density, minimizes resistive heating, and enhances overall current-carrying capacity and safety.

• High-Purity Copper & Fire-Resistant Design: The conductor utilizes a high-purity red copper core for minimal resistivity. Combined with the flame-retardant and waterproof rubber jacket, it ensures stable and safe electrical connections under complex operating conditions, offering excellent fire-resistant performance.

• Efficient Internal Water Cooling Circulation: The unique annular water channel design allows for full contact between the coolant and the conductor. It provides a short, efficient heat dissipation path, rapidly removing Joule heat generated by high currents, ensuring controlled cable temperature rise.

• Excellent Dynamic Bending Performance: The overall structure is flexible with a small minimum bending radius and high resistance to torsional fatigue. It can withstand frequent movement and bending during equipment operation without compromising the integrity of the internal water and electrical circuits.

• Long Economic Service Life: Built with premium materials and a robust structure, the product offers an exceptionally long service life and high reliability. Its low maintenance requirements deliver excellent long-term value for users.
