Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The mica glass tape and XLPE insulation core is designed to maintain circuit integrity and continue operating for a specified period under direct flame, which is essential for all emergency and life-safety circuits.
-
High Flexibility & Lightweight: As an unarmored cable, it offers excellent flexibility and reduced weight, facilitating easier and faster installation in conduits, cable trays, and control panels.
-
Cost-Effective Safety Solution: Provides the critical feature of certified fire resistance with a practical PVC sheath, offering a reliable safety solution for applications where this specific performance is mandated.
-
Flame Retardant: Complies with IEC 60332-1 and IEC 60332-3-22, helping to inhibit the spread of flame along the cable run.
Standards & Compliance
This cable is designed and tested in accordance with key international safety standards:
-
IEC 60092-350, 353 (General construction and requirements)
-
IEC 60228 (Conductors)
-
IEC 60092-360 (Insulation and sheath)
