Class I Division 1 cable

The nominal overall diameter (O.D.) of a Nexans AmerCable 37-102594BS 2/C #4 AWG 600/1000V bronze armored and sheathed marine power cable is approximately 28.45 mm (1.120 inches), with a standard tolerance window of ±1.0–1.5 mm producing a permissible range of 26.95–29.95 mm. The cable features two parallel Class 5 tinned copper main power conductors each rated for 4 AWG (approximately 21.2 mm² cross-section), with a Gexol® XLPO (cross-linked polyolefin) insulation system providing superior low-frequency and high-frequency electrical integrity for 600/1000V marine applications. The outer protective architecture comprises a high-density bronze wire braid armor layer (approximately 1.5–2.0 mm thickness) specifically engineered to resist saltwater corrosion and mechanical abuse, overlaid with an arctic-grade halogen-free thermosetting rubber jacket (approximately 2.0–2.5 mm thickness) providing extreme durability in harsh offshore, subsea, and deep-freeze industrial environments. The approximate total weight is ~1,380 kg/km (927 lbs/1000 ft), with pure copper content approximately 380 kg/km. This cable achieves IEEE 1580 Type P certification, meeting or exceeding all critical flame-retardance, electrical stress distribution, and mechanical protection requirements for offshore drilling platforms, large vessel power systems, subsea equipment power distribution, and Class I Division 1 hazardous zone installations where conventional industrial cables cannot operate safely.
