Ancor Flat Triplex Cable 12/3 AWG 100 ft — Marine-Grade Tinned Copper, UV & Chemical Resistant

Ancor Flat Triplex Cable 12/3 AWG (100 ft) is a marine-grade, tinned-copper, ultra-flexible power cable engineered for durable electrical runs aboard boats and harsh outdoor environments.

This 100-foot roll of 12/3 AWG triplex cable combines heavy-duty conductivity with a low-profile flat layout to simplify installation in tight spaces. Built to meet and exceed maritime standards, the cable is formulated for long-term performance where salt, vibration and exposure to fuels or sunlight would quickly degrade ordinary wiring. The design prioritizes corrosion resistance and flexibility so it can be routed, fastened, and flexed without brittle failure.

What makes this cable suitable for marine and harsh environments?

The cable uses fine, tinned copper strands that limit corrosion and electrolysis, while the premium vinyl jacket resists chemicals and UV exposure. Temperature and voltage ratings are aligned with demanding marine electrical systems to maintain safety and function over time.

• Tinned copper (Type 3) stranding for corrosion resistance and flex fatigue protection
• Vinyl insulation rated 600 V with high heat tolerance (105°C dry, 75°C wet)
• Formulation resists salt water, battery acid, gasoline, oil and UV

How does the flat triplex shape help during installation?

The flat profile keeps three conductors together in a compact form that lays neatly against hulls, bulkheads and under flooring. That low profile reduces bulging and makes it easier to secure with clamps or adhesive channels, speeding runs and yielding a cleaner finish.

• Flat geometry minimizes space taken behind panels and in cable trays
• Grouped conductors simplify routing and labeling for DC systems
• Ease of fastening reduces chafe points and improves neatness

Is this cable flexible enough for engine compartments and moving parts?

Yes — the ultra-flexible tinned copper stranding and soft vinyl jacket retain pliability even at very low temperatures, so the cable resists cracking and fatigue where vibration or motion occur. It’s intended for repeated flexing common near engines, throttles, and steering assemblies.

• Type 3 tinned strands resist vibration-induced wire breakage
• Stays flexible down to around -40°F/C to prevent brittleness
• Durable jacket withstands abrasion where movement contacts surfaces

What electrical and safety standards does this product meet?

The cable is manufactured to exceed recognized marine and safety benchmarks so it can be confidently used in recreational and commercial marine builds. These standards reflect electrical insulation, mechanical resilience and environmental resistance relevant to boats and workboats.

• Meets or exceeds UL 1426 marine wire criteria
• Complies with ABYC guidelines used in marine electrical systems
• Aligned with U.S. Coast Guard charter-boat wiring requirements (CFR Title 46)

Who is this for: This 12/3 AWG, 100-foot Ancor flat triplex cable suits boat owners, marine electricians, shipyards, and anyone running DC power in moisture-prone or high-vibration settings. It’s ideal when you need a compact, corrosion-resistant run for battery feeds, distribution panels, bilge pumps, or other onboard loads where flexibility and durability are priorities.
