Product Overview
The CHEF82/SA is a robust, fully protected marine communication cable designed for critical data and signal transmission in demanding environments. It features Ethylene Propylene Rubber (EPR) insulation for superior signal integrity, a durable Polychloroprene (PCP) inner sheath, tinned copper wire braid armor for EMI shielding, and a protective PVC outer sheath. This complete construction ensures reliable performance for telecommunications, instrumentation, and data processing systems on ships, offshore platforms, and in industrial facilities where both signal clarity and mechanical durability are essential.

Key Performance Characteristics
-
Superior Signal Integrity: EPR insulation provides stable dielectric properties and low signal attenuation, which is crucial for high-quality data and voice transmission.
-
Complete EMI Shielding & Protection: The tinned copper wire braid armor offers excellent electromagnetic interference (EMI) shielding. The additional PVC outer sheath provides a full protective layer against mechanical damage, abrasion, moisture, and chemicals for the internal components.
-
Environmental Durability: The Polychloroprene (PCP, Neoprene) inner sheath ensures resistance to oils, ozone, and weathering.
-
Bunched Flame Retardancy (SA): Complies with IEC 60332-1 and IEC 60332-3-22 for flame retardancy when installed in bunches, enhancing safety in cable runs.
-
Halogen-Free Option (Based on Materials): While rated "SA", the PCP inner sheath and construction may offer low halogen emission properties, enhancing safety in case of fire (refer to specific test reports).
