Description

H01N2-D EN 50525-2-81 welding cable is a heavy-duty, single-core cable specifically engineered for high-current power transmission in demanding industrial settings. It is defined by its exceptional flexibility, achieved through the use of class 6 extra-fine copper conductors which allow for easy handling and routing in confined spaces. The core is protected by a robust polychloroprene or equivalent synthetic rubber sheath that provides a high level of physical durability. This outer jacket is designed to resist tearing and abrasion while remaining resilient against chemical exposure, including contact with oils, acids, and common industrial solvents.

This cable is primarily utilised as a flexible connection between welding generators and electrode holders or workpieces in manual and automated arc-welding systems. Its rugged construction makes it an industry standard for automotive manufacturing assembly lines, shipbuilding, and conveyor systems where cables are subject to frequent movement and mechanical stress. Beyond welding, it is frequently employed in battery energy storage systems for interconnecting battery banks and as a temporary power link in harsh construction environments. Because the sheath is resistant to ozone and ultraviolet radiation, the cable performs reliably in both damp indoor settings and exposed outdoor locations.

Technically, the cable is rated for a nominal voltage of 100V and is designed to operate safely within a temperature range of -25 to +85 degrees Celsius when flexed. Its current-carrying capacity is highly dependent on the duty cycle of the equipment; for instance, a 50mm section can handle approximately 285A at a continuous load but may support up to 480A during intermittent manual use. To maintain its structural integrity and ensure a long service life, the cable typically requires a minimum bending radius of twelve times its outer diameter. Furthermore, the flame-retardant properties of the rubber compound ensure compliance with international safety standards, preventing the spread of fire in the event of high thermal exposure.
