CAT7A Marine 4x(2x23 AWG/7)

SH-DATA Ethernet Cat.7A

Ethernet cable approved for marine and offshore use

• Marine/offshore approved Ethernet cable.
• Category 7A construction intended for high-performance, low-noise networking in harsh environments.
• Shielding architecture (pair foil + overall braid) helps reduce EMI and improve signal integrity.
• Fire-safety focused design: flame propagation tests, low smoke emission, and halogen-related requirements are listed.
• Two jacket compound options (SHF1 / SHF2) to match installation needs; SHF2 adds stronger environmental/chemical resistance (oil/salt water/weathering).

Construction details

• Conductor: stranded bare copper (7 strands).
• Insulation: foam-skin polyethylene (EN 50290-2-23 referenced).
• Pair colors: white/blue-blue, white/orange-orange, white/green-green, white/brown-brown.
• Pair screen: aluminum/polyester tape (aluminum surface outside).
• Assembly: shielded pairs stranded together.
• Overall shield: tinned copper braid with 85% coverage.
• Outer jacket: SHF1 or SHF2 compound (IEC 60092-360 referenced); colors listed include grey (SHF1) and black (SHF2).

Fire behaviour and safety standards listed

• IEC 60332-3-22 (bunched cable / no fire propagation).
• IEC 60332-1-2 (single cable / no flame propagation).
• IEC 60754-1 and IEC 60754-2 (halogen content and halogen-related conductivity).
• IEC 61034 (smoke emission / smoke density).

Chemical and environmental resistance

• SHF1: UV resistant according to UL 758 (datasheet notes protection recommendations for contact with salty water/nebulation).
• SHF2: UV resistant (UL 758) and oil resistant (UL 758); also references IEC 60092-360 table 9.10 for resistance to salty water and weathering.
• Temperature range: -15°C to +90°C (SHF1) and -40°C to +90°C (SHF2).
• Minimum bending radius: 10x outer diameter.

Key electrical characteristics

• Max DC conductor resistance at 20°C: 74.5 Ω/km (23 AWG).
• Capacitance: 45 pF/m (23 AWG).
• Characteristic impedance (1–100 MHz): 100 Ω (±15%).
• Voltage rating: 125 V.
• Minimum insulation resistance: 5.0 GΩ·km.
• Nominal velocity of propagation (100 MHz): 77%.
• Nominal attenuation: 600 MHz = 66.1/49.5/47.6 dB/100m.

Key mechanical characteristics

• Nominal weight: 92 kg/km (23 AWG).
• Nominal outer diameter: 8.4 mm (23 AWG).

Standards referenced

• EN 50173.
• EN 50288-4-2.
• IEC 61156-6.
• TIA/EIA 568 B.2.
