What is a Fire Resistant Cable?
In brief, flame retardant cables are designed to self-extinguish within set parameters and resist the spread of fire into a new area.
Fire-resistant or fire-rated cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined conditions.

What is another name for fire-resistant cable?
LSZH Flame Retardant (FRT) Cable
To ensure safety during a fire, FRT cable typically uses LSZH material. LSZH produces little smoke or acidic gas when burned**, so LSZH FRT cable also undergoes acid gas emission tests to IEC 60754 or BS EN 60754 and smoke emission tests to IEC 61034 or BS EN 61034.
What material is used for fire-resistant cable?
Fire-resistant cables may be single-core or multi-core constructions. The insulation material can be elastomeric materials (XLPE, EPR, SiR, or LSOH) instead of thermoplastic (EVA, PE, or PVC) to meet stringent environmental requirements.
How do you make a cable fire-resistant?
The fire protection coating on cables is a thin, water-based liquid applied to the cable by a spray gun or brush. The coating will prevent the cables from being ignited by a flame or spark.
The fire retardant coating has been around for decades, and it has been used extensively in industrial settings.
How thick is fire cable?

What voltage is a fire cable?
Power Limited Fire Alarm Wires typically work at 24 volts DC, whereas non-power-limited cables run at 120 volts AC. Non-power-limited cables are typically obsolete since low-voltage cable offers greater benefits.
Is fiber cable fire-resistant?
The fire-resistant fiber cable design ensures operation for up to 30-60-90, 120 & 180 minutes under a fire of 750C. 2 hours of fire-rated fiber optic cables are available with various design options. Armored,, Un-armored, Single or Double jacketed.
