Fire-resistant ng-FRLS LTx power cables with a mica fire barrier
TCG fire-resistant power cables for fire protection systems, emergency lighting, firefighters' lifts and other critical loads. The construction includes a thermal barrier of mica-containing tapes, which keeps the cable operational at a fire temperature of ≥750°C for at least 90 minutes. Insulation and sheath of low-fire-hazard PVC compound (ng, cat. A) with low smoke emission (LS).
