Key Performance Characteristics
-
Stable Signal Transmission: EPR insulation ensures excellent dielectric properties for consistent signal integrity, minimizing loss in data, voice, and instrumentation circuits.
-
Environmental Durability: The Polychloroprene (PCP, Neoprene) sheath provides robust protection against oils, ozone, weathering, and abrasion, safeguarding the internal conductors.
-
High Flexibility & Lightweight: The unarmored design makes the cable highly flexible and easy to install in conduits, cable trays, and control panels within protected spaces.
-
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 flame spread.
-
Designed for Internal Networks: Ideal for fixed, protected installations where mechanical armor is not required but reliability and safety are essential.
