Extra Flexible Double Insulated Welding and Battery Power Cable
Engineered for maximum power delivery and durability. CableApex’s welding and battery cables utilize high-strand count 99.99% Oxygen-Free Copper (OFC) to ensure minimal voltage drop and heat generation. The double-insulation system—featuring a robust TPE or EPDM outer jacket—provides superior resistance to chemicals, oil, and abrasion. With a flexibility rating that exceeds standard Class 5 conductors, our cables are ideal for tight-radius routing in battery racks and heavy-duty welding environments.
Our conductor resistance strictly complies with the IEC 60228 standard (e.g., at 20°C, the resistance of a 35 mm² conductor is less than 0.524 Ω/km), preventing energy loss in high-current applications.
Maximum Flexibility meets Heavy Duty Power
Unlike standard rigid power cables, our welding and battery cables are constructed with thousands of ultra-fine annealed copper strands. This “rope-lay” design ensures that even thick cables (up to 120mm² and beyond) remain exceptionally flexible, preventing operator fatigue and allowing easy routing in tight battery compartments.
Double Insulation for Double Safety
We prioritize safety in harsh environments. Our cables feature a dual-layer insulation system:
-
Inner Layer: A specialized separator layer to prevent conductor oxidation and improve flexibility.
-
Outer Layer: A tough, oil-resistant, and flame-retardant jacket (Rubber or Special PVC) that withstands cuts, tears, and abrasion on rough factory floors.
