Product Overview
The CJVR80/NA is a specialized fire-resistant marine flexible power cable designed for critical circuits where maintaining circuit integrity during a fire is the primary safety requirement. It features a fire-resistant core of mica glass tape and XLPE insulation, a PVC inner sheath, and tinned copper wire braid armor. This construction provides certified circuit survival under fire conditions along with flexibility and electromagnetic shielding, making it suitable for essential safety systems in cost-effective applications where halogen-free properties are not specified.

Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The mica glass tape and XLPE insulation system ensures the cable maintains electrical circuit integrity and continues to operate for a specified period under direct flame, which is essential for emergency and safety circuits.
-
Effective EMI Shielding: The tinned copper wire braid armor provides reliable electromagnetic interference (EMI) shielding, protecting sensitive control and power signals.
-
Cost-Effective Fire Safety Solution: Offers the critical feature of fire resistance with a PVC sheath, providing a practical solution for applications where this specific safety performance is required without the need for halogen-free materials.
-
Good Flexibility: The stranded conductor and braided armor design allow for sufficient flexibility for installation in control panels and cable trays.
Standards & Compliance
This cable is designed and tested in accordance with key international safety standards:
-
IEC 60092-350, 353 (General construction and armor)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath)
