A 10 mm 4-core TRS fire-resistant cable is a heavy-duty electrical cable designed for applications requiring high durability, mechanical protection, and the ability to maintain circuit integrity during a fire.
Specifications
Key Characteristics and Features
Conductor: Typically features stranded or flexible annealed copper conductors, with a cross-section of 10 mm².
Insulation: The individual cores usually have XLPE (Cross-Linked Polyethylene) or a similar high-temperature insulation, which offers good heat stability and resistance to various fluids.
Sheath (TRS): The outer sheath is made of a heavy-duty rubber compound (TRS) which is known for excellent abrasion, chemical, grease, oil, acid, and sunlight resistance, making it suitable for demanding environments.
Fire Resistance: The cable is specifically designed and tested to maintain electrical function during exposure to fire for a specified duration, often meeting standards like IEC 60331-25.
Voltage Rating: Commonly rated for 600/1000V or similar medium-voltage applications.
Temperature Rating: The fixed installation temperature range is typically between -25°C to +90°C, with some fire-rated versions handling continuous operation at 110°C.
