Industrial-Grade SA 50A Heavy Duty Cable for High-Power Battery Charging
Meet the ultimate power solution for industrial energy demands: our SA 50A Heavy Duty Charging Cable , engineered to deliver 50A continuous current for rapid, efficient charging of heavy-duty batteries in mining trucks, marine vessels, and renewable energy storage systems. Built with UL3271#8AWG conductors and industrial-grade connectors, this Heavy Duty Cable minimizes resistance and heat buildup, ensuring peak performance in extreme temperatures (-40°C to 125°C) and corrosive environments.
Military-Spec Components & Technical Precision
Cables :
UL3271#8AWG (Black/Red): 8-gauge stranded copper with flame-retardant PVC insulation (600V rating), designed for 50A+ current and unmatched flexibility.
Connectors :
Connectors 1 : SA 50A connector *2PCS with tin-plated cold-press terminals for ultra-low resistance and oxidation-free power transfer.
Connectors 2-3 : R5.5-5 O-ring terminals *2PCS, featuring IP68-rated seals to block moisture, dust, and chemical ingress.
Customization : Add laser-etched logos, adjust lengths (1m–15m), or opt for high-visibility jackets (e.g., yellow) for safety-critical zones.
Packaging : Individually wrapped in anti-static PE bags, protected by ballistic-grade outer layers, or shipped in OEM-branded blister packs.
Uncompromising Quality & Compliance
Every Industrial Cable undergoes 100% load testing (50A/12hr cycles), continuity checks, and pull-force validation on terminals. Compliant with RoHS & REACH standards , it’s engineered for eco-safety in sensitive industrial and marine ecosystems. With flexible MOQs (starting at 30 units) and 5-day lead times , we empower rapid scaling for EV fleets, grid storage, or emergency power systems.
Tailor-Made for Extreme Applications
Why risk subpar cables? Our Custom Cable services let you:
Upgrade to UL3271#6AWG for 80A+ ultra-high-current demands.
Replace O-ring terminals with M8/M12 connectors for automated docking systems.
Integrate thermal sensors or RFID chips for smart charging management.
From electric excavators to offshore battery banks, we craft Heavy Duty Cable solutions that align with your toughest operational needs.
Why Choose the SA 50A Industrial Cable?
Unlike generic alternatives, our Heavy Duty Cable features SA 50A connectors with cold-pressed tin plating, eliminating arcing and voltage drop under heavy loads. The R5.5-5 terminals ensure leak-proof connections in submerged or dusty environments, while UL-certified materials guarantee global compliance. Trust a Custom Cable built to power your mission-critical systems—backed by a lifetime technical support and a 5-year warranty.
