Key Performance Characteristics
-
Superior Mechanical Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, and abrasion, safeguarding delicate communication circuits in exposed or high-risk areas.
-
Stable Signal Performance: EPR insulation ensures excellent dielectric properties and signal integrity, which is critical for accurate data and telecommunication transmission.
-
Environmental Durability: The Polychloroprene (PCP, Neoprene) inner sheath offers strong resistance to oils, ozone, weathering, and chemicals.
-
Bunched Flame Retardancy (SA): Complies with IEC 60332-1 and IEC 60332-3-22 for flame retardancy when installed in bunched configurations, helping to inhibit the spread of fire.
-
Designed for Fixed Installations: Provides long-term reliability in fixed marine and industrial communication networks.
