Product Overview
The CHJPJ90/SC is a high-specification Low Smoke Halogen Free (LSHF), Flame Retardant Marine Communication Cable designed for critical signal transmission. It features XLPE (Cross-Linked Polyethylene) insulation for superior electrical performance and a Galvanized Steel Wire Braid armor for maximum mechanical protection. This version is constructed without an outer sheath (Code 0), making it suitable for specific installation requirements within conduits, trays, or as a component in multi-cable systems where an overall jacket is not needed or is separately specified.
Key Features & Benefits
-
Comprehensive Fire Safety: Meets Halogen-Free (IEC 60754) and Low Smoke (IEC 61034) standards, minimizing toxic fumes and smoke opacity. It is also Flame Retardant (IEC 60332-1 & -3-22), helping to prevent fire spread.
-
High-Performance Insulation: XLPE insulation ensures excellent thermal endurance (rated for 90°C), high dielectric strength, and resistance to environmental stress cracking.
-
Robust Armored Core: The Galvanized Steel Wire Braid armor provides essential protection against mechanical impact, crushing, and rodent damage. The Cross-linked Polyolefin (SHF2) inner sheath maintains the LSHF integrity.
-
Flexible Installation Design: The "Without Outer Sheath" construction offers installation flexibility for engineers, allowing the cable to be used in contained systems or where an overall jacket is applied separately.
