High Conductivity Spot Welder Water Cooling Secondary Cable Stable Current Transmission

The Secondary Cable is a uniquely structured specialty insulated conductor, designed for industrial applications involving low voltage and high current. It utilizes multiple strands of extra-soft oxygen-free copper wire as the core conductor, sheathed in a high-performance rubber water hose. An efficient annular circulating cooling channel is formed between the conductor and the hose. Both ends of the cable are integrally connected to all-copper terminals via welding, reinforced with stainless steel ferrules for sealing and fixation. The terminals feature integrated water ports that connect seamlessly with the internal cooling passage. This integrated design allows it to carry extremely high operating currents while maintaining an exceptionally small cross-sectional area, coupled with effective thermal management via internal water cooling. Its superior bending and movement capabilities make it a critical component for the efficient and reliable transmission of both power and coolant in dynamic applications such as automated welding equipment and medium-frequency induction heating systems

• High-Purity Conductor & Low-Impedance Transmission: Utilizes a high-purity oxygen-free copper conductor to minimize electrical impedance from the power source to the load, effectively reducing energy loss and providing stable, efficient power for high-wattage equipment.

• Exceptional Flexibility for Dynamic Operation: Engineered for continuous movement, the structure offers outstanding flexibility and resistance to repeated bending fatigue. It performs reliably along complex motion paths without compromising the integrity of the internal water and electrical circuits.

• Optimized Fluid Dynamics & Heat Dissipation: The carefully engineered water channel design results in minimal water pressure drop. Efficient coolant circulation delivers excellent heat dissipation, ensuring the cable maintains a stable, low-temperature operating state under sustained high loads.

• Multi-Layer Physical & Environmental Protection: The special rubber outer jacket and internal reinforcement structure provide superior resistance to high pressure, high temperature, abrasion, and chemical corrosion. The core components offer maximum torsion and compression resistance, adapting to harsh industrial environments.

• Minimal Magnetic Induction & Interference: Special conductor stranding techniques and structural design significantly reduce the self and mutual inductance during operation, achieving industry-leading low magnetic induction impact and minimizing electromagnetic interference with nearby sensitive electronic equipment.

• Convenient Modular Maintenance: Standardized connection interfaces and reliable termination processes enable quick and easy replacement and installation on-site, greatly simplifying maintenance procedures and enhancing overall equipment availability and operational efficiency.

• Long Life & Cost-Effectiveness: Selected high-quality, durable materials combined with advanced manufacturing processes grant the product an extended service life and high operational reliability. Coupled with low maintenance requirements, it delivers excellent total cost of ownership and return on investment over its lifecycle
