Smooth Motion, Strong Connection:
SVS Standards for Connection Cables

Connection cables are made from multi-stranded copper conductors with a tightly twisted structure. This design provides high flexibility while maintaining stable conductivity and shape retention, even under frequent movement. A heat-resistant insulation protects against process-related thermal exposure. Form-fitting ends and precisely machined connector heads ensure low-loss current transfer during continuous operation.

Available as standard versions or custom designs based on drawings or samples. Geometry, interfaces, and materials are precisely matched to your specific requirements.

  • Air-cooled connection cable for resistance welding

    Air-cooled connection cables conduct welding current reliably without the need for additional cooling. They consist of flexible copper strands with heat-resistant insulation and are designed for moderate current loads and shorter welding cycles. Strand count, cross-section and insulation are tailored to current level, mechanical stress and ambient temperature.

Fundamentals

Function of Connection Cables

Connection cables ensure reliable current transfer between fixed and moving components. Their internal structure consists of numerous fine copper strands that provide uniform current distribution and excellent flexibility. This allows them to remain conductive and dimensionally stable even under repeated motion. Water-cooled versions include integrated cooling channels that efficiently dissipate heat generated during operation.

Key Parameters of Connection Cables

  • The arrangement of individual wires affects current-carrying capacity and heat generation. Fine-stranded conductors distribute current evenly and minimize internal resistance.

  • Air- or water-cooled versions dissipate process heat in different ways. The appropriate cooling principle determines service life, load capacity, and installation conditions.

  • The connections must remain pressure- and temperature-resistant over time. Only reliably sealed joints maintain stable cooling performance and ensure consistent operation under continuous load.
