Product Overview
The CJPJR90/SC is a halogen-free, flame-retardant marine flexible power cable engineered for applications that demand a combination of high-temperature sheath resistance, superior mechanical protection, and installation flexibility. It features a cross-linked polyolefin (SHF2) inner sheath, fine-stranded Class 5/6 conductors, XLPE insulation, and galvanized steel wire braid armor. This design offers robust durability for demanding power and control circuits in high-heat or mechanically challenging environments on vessels and offshore installations.

Key Performance Characteristics
-
High-Temperature Resistant Sheath: The inner sheath utilizes cross-linked polyolefin (SHF2, code PJ), a material designed for improved thermal performance and stability in elevated temperature environments compared to standard thermoplastic sheaths.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides excellent resistance to crushing, impact, and tensile stress, making the cable suitable for exposed or hazardous routing paths.
-
Flexible & Robust Design: Despite the heavy-duty steel armor, the fine-stranded (Class 5/6) tinned copper conductors ensure the cable retains essential flexibility for installation in complex cable trays and confined spaces.
-
Flame Retardant Safety: Complies with IEC 60332-1 and IEC 60332-3-22, effectively inhibiting the spread of flame along the cable.
-
Halogen Free & Low Smoke: The construction materials are halogen-free and generate low smoke density, enhancing safety by reducing corrosive gas emission and improving visibility in case of fire.
Standards & Compliance
This cable is manufactured in accordance with the following international standards:
-
IEC 60092-350, 353 (General construction and tests for shipboard power cables)
-
IEC 60228 (Conductors of insulated cables)
-
IEC 60092-360 (Insulating and sheathing materials)
-
IEC 60332-1 & IEC 60332-3-22 (Tests for flame retardancy)
Typical Applications
This armored flexible cable is ideal for applications where high mechanical strength and resistance to a warmer ambient environment are required simultaneously:
-
Marine & Offshore: Power and control circuits in engine rooms, for auxiliary machinery, in areas with higher ambient temperatures, and on offshore platforms where cables may be exposed to physical impact and require robust protection.
-
Industrial: Flexible yet heavily protected wiring in industrial plants such as metallurgy, mining, and heavy machinery where high ambient heat and significant mechanical stress are present.
