Product Overview
The CHEF92/SA is a heavy-duty, fully protected marine communication cable engineered for critical data and signal transmission in the most demanding environments. It combines stable Ethylene Propylene Rubber (EPR) insulation, a robust Polychloroprene (PCP) inner sheath, galvanized steel wire armor for supreme mechanical protection, and a complete PVC outer sheath. This dual-layer armored design ensures maximum durability and signal integrity for telecommunications, instrumentation, and control systems on ships, offshore platforms, and in harsh industrial facilities.

Key Performance Characteristics
-
Maximum Mechanical & Environmental Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, and abrasion. The additional PVC outer sheath fully encapsulates the armor, offering a secondary barrier against moisture, chemicals, abrasion, and corrosion for long-term reliability in exposed areas.
-
Stable Signal Integrity: EPR insulation ensures consistent dielectric properties and minimal signal attenuation, which is crucial for reliable data, voice, and instrumentation transmission.
-
Durable Inner Protection: The Polychloroprene (PCP, Neoprene) inner sheath provides inherent 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 trays and runs.
-
Designed for Fixed, Harsh Environments: Provides an all-in-one solution for communication networks where physical durability is as critical as signal performance.
Standards & Compliance
This communication cable is designed and manufactured in accordance with key international marine standards:
