#3/0 - 3/0 AWG Flexoprene Welding Cable, Sold Per Foot

Technical Overview of 3/0 Flexoprene Welding Cable

The CBL#3/0 is a premium-grade 3/0 American Wire Gauge (AWG) welding cable designed for high-amperage power transfer in industrial environments. Engineered with a high strand count of annealed bare copper, this cable maximizes conductivity while minimizing the skin effect often seen in solid conductors. The core is encased in a specialized Flexoprene jacket, a formulation of Ethylene Propylene Diene Monomer (EPDM) rubber. This insulation material is critical for industrial safety and longevity, offering a dielectric strength sufficient for 600-volt applications and a thermal operating range spanning from -50°C to +105°C.

From a mechanical perspective, the Flexoprene jacket provides exceptional resistance to abrasion, impact, and tear propagation. It is chemically resistant to oils, acids, alkalis, and solvents commonly found in MRO (Maintenance, Repair, and Operations) settings. The cable is designed to meet or exceed SAE J1127 and ASTM standards for welding cable, ensuring reliable performance under continuous load. The 3/0 gauge size is typically rated for amperages between 300A and 350A depending on the duty cycle and cable length, making it suitable for heavy-duty arc welding machines, power inverters, and battery bank interconnects.

This product is sold by the foot, allowing for precise procurement based on specific project requirements, reducing waste and cost. The cable's high flexibility facilitates easy routing through conduit, cable trays, or around tight machinery corners without compromising the insulation integrity. It serves as an optimal solution for secondary voltage resistance welding leads, power supply applications not exceeding 600 volts AC, and temporary power distribution.
