Key Performance Characteristics
-
Certified Fire Resistance (IEC 60331): The mica glass tape and XLPE insulation system ensures the cable maintains circuit integrity and continues to function for a specified period under direct flame, which is critical for life-safety and emergency circuits.
-
Maximum Mechanical Protection: The galvanized steel wire braid armor provides exceptional resistance to crushing, impact, and tensile stresses, protecting the critical fire-resistant core in exposed or hazardous locations.
-
Cost-Effective Durability: Offers a robust, fire-safe cable solution with the economic and protective advantages of a PVC inner sheath and steel armor, suitable for applications where halogen-free properties are not specified.
