Industrial-Grade SA 40A Heavy Duty Cable for High-Current Battery Charging
Power your heavy-duty equipment with unmatched reliability using our SA 40A Heavy Duty Charging Cable , engineered for industrial-scale battery charging in mining, construction, and marine applications. Built to handle 40A continuous current, this Heavy Duty Cable combines UL3271#10AWG conductors with rugged connectors, ensuring rapid, safe charging for lithium-ion packs, AGVs, and backup power systems. Its oil-resistant, high-temperature design thrives in harsh environments, delivering zero voltage drop even at peak loads.
Industrial-Strength Components & Specifications
Cables :
UL3271#10AWG (Black/Red): 10-gauge stranded copper with PVC insulation (600V rating), optimized for 40A+ current and flexibility in tight spaces.
Connectors :
Connectors 1 : SA 40A connector *2PCS with tin-plated cold-press terminals for corrosion-free, low-resistance power transfer.
Connectors 2-3 : 90° R5.5-5 O-ring terminals *2PCS + M5 screw sets, ensuring watertight seals (IP68-rated) in humid or dusty conditions.
Customization : Add branded stickers, adjust cable lengths (1m–10m), or opt for high-visibility orange jackets.
Packaging : Choose individual PE bags, retail-ready blister packs, or OEM-branded boxes with foam inserts.
Rigorous Testing & Compliance
Every Industrial Cable undergoes 100% load cycling, continuity, and insulation resistance tests , validating its 40A/600V endurance. Compliant with RoHS & REACH standards , it’s free from hazardous substances, making it safe for use near sensitive electronics. With flexible MOQs (starting at 50 units) and 7-day lead times , we support rapid deployments for emergency fleet charging or custom EV projects.
Tailored for Extreme Conditions
Why risk underpowered cables? Our Custom Cable solutions allow:
Upgrading to #8AWG UL3271 for 60A+ applications.
Replacing O-ring terminals with laser-welded lugs for vibration-heavy machinery.
Integrating temperature sensors or RFID tags for smart charging systems.
From mining trucks to offshore battery banks, we engineer Heavy Duty Cable kits that match your operational demands.
Why Choose SA 40A Industrial Cable?
Unlike generic charging wires, our Heavy Duty Cable features cold-pressed SA 40A connectors that eliminate arcing risks, while the 90° O-ring terminals prevent moisture ingress in submerged environments. The UL-certified construction ensures compliance with global safety standards, and the customizable branding reinforces your corporate identity. Trust a Custom Cable built to outlast your toughest jobs—backed by a 5-year warranty and 24/7 support.
