Reliable power transmission: SVS standards for connection cables
Our connection cables are made of multi-strand copper conductors with a tightly twisted structure. The number and arrangement of the strands ensure that the cable remains conductive and dimensionally stable even under repeated bending and twisting. Heat-resistant insulation protects the conductors from process-related temperature effects. The cable ends are form-fitting and equipped with precisely fitting terminal heads that ensure a secure and low-loss connection.
Available in standard versions or customized according to drawing or sample. We tailor the design and interface precisely to your system and process requirements.

Applications
Core function of connection cables
Connection cables connect fixed and moving components in the welding system. Their internal structure, made up of numerous fine copper wires, conducts current evenly and allows for good flexibility. This ensures that they remain conductive and dimensionally stable even during repeated movement. Water-cooled versions also have integrated channels for cooling water to directly dissipate generated heat.
Quality-relevant features of connection cables
The material quality directly influences current-carrying capacity, temperature behavior, and service life. Oxygen-free copper ensures high conductivity and low heat loss during operation. Electrolytically pure copper also provides mechanical stability under dynamic loads.
The structure of the copper strand influences current-carrying capacity and heating behavior. Fine-wire conductors with a uniform arrangement reduce internal resistance and enable low-loss current distribution.
Depending on the application, air- or water-cooled versions are available. The choice of the appropriate cooling principle influences heat dissipation, service life, and installation conditions.
Connections must remain pressure- and temperature-resistant over time. Only long-lasting, sealed connections maintain effective cooling and ensure system reliability throughout the entire operating period.
