Dual Armored Cable

Dual armored cable is built for harsh installations where mechanical protection and uptime matter. Featuring two layers of armor—commonly steel wire or corrugated steel tape over an inner armor—these cables deliver superior crush resistance, impact protection, and rodent deterrence. They’re a smart choice for direct burial in rocky soil, heavy-traffic plants, tunnels, refineries, mining sites, offshore platforms, and coastal or marine routes.

Available as power, control, instrumentation, and fiber optic constructions, dual armored designs safeguard conductors and optical fibers from abrasion and moisture while maintaining pulling strength over long runs. Typical jackets include PVC, PE, or LSZH for chemical, UV, and flame performance, with insulation options like XLPE for higher temperature and voltage ratings.

Benefits you’ll notice:
- Reduced downtime from cuts, crushing, and gnawing
- Safer circuits thanks to robust grounding through metallic armor
- Lower total cost of ownership in demanding environments
- Confident direct burial without conduit in many applications

How to choose the right dual armored cable:
- Application: power, control, or fiber; indoor, outdoor, tray, or buried
- Conductor: copper or aluminum; gauge and ampacity
- Armor type: steel wire (SWA) for tensile and crush strength, aluminum wire (AWA) for single-core AC magnetic performance, or steel tape for radial protection
- Jacket: PVC, PE, or LSZH based on chemical exposure and fire codes
- Ratings and codes: IEC 60502, BS 5467/6724, IEEE/ICEA, or UL listings as required
- Installation limits: minimum bend radius and maximum pulling tension

Plan accessories early: glands, cleats, lugs, heat-shrink boots, splice closures for fiber, and bonding kits to earth the armor safely. Store reels dry, avoid sharp bends, and test insulation or fiber attenuation before energizing. If you need robust direct-burial, rodent-resistant, industrial-grade performance, dual armored cable provides confidence from design through commissioning. Ideal for mining, oil and gas projects.
