A 50mm, 4-core, flexible, TRS, fire-resistant cable is a heavy-duty power cable designed for applications requiring both durability and continued functionality during a fire.
Specifications
- <p>Key Characteristics</p><p>Size: 50 sq mm cross-sectional area per core, suitable for handling medium to high current loads, with current ratings often around 181 Amps for copper conductors.</p><p>Cores: 4 cores, allowing for use in three-phase systems with a neutral, or other complex wiring configurations.</p><p>Flexibility: "Flexible" and "TRS" (Tough Rubber Sheath, though often PVC is now used) implies a construction that is easy to install, route in tight spaces, and suitable for applications where the cable might be moved (e.g., industrial machinery or temporary power). Flexible cables typically use Class 5 or Class 6 stranded copper conductors.</p><p>Fire Resistance: This is a crucial safety feature. The cable is designed to maintain circuit integrity and continue to operate in fire conditions for a specified period (e.g., 2 hours, depending on the specific standard like AS/NZS 3013). This is distinct from standard flame-retardant cables, which merely prevent the spread of fire but do not necessarily continue to function during one.</p><p>Sheath/Insulation: Typically features high-quality insulation like XLPE (Cross-linked polyethylene) and an outer sheath made of materials like PVC or Low Smoke Zero Halogen (LSZH) compounds, which are often used in fire-rated cables to minimize hazardous smoke emission. </p>
