When it comes to electrical wiring for homes, offices, and industrial setups, safety and performance are non-negotiable. With a wide range of wire types available today, it's essential to understand what each offers especially when choosing between FR (Flame Retardant), FRLS (Flame Retardant Low Smoke), and ZHFR (Zero Halogen Flame Retardant) wires.
Let’s break down the differences, benefits, and ideal applications of each type.
🔹 FR (Flame Retardant) Wires
What are they?
FR wires are standard house wires designed to resist the spread of flames in the event of a fire.
Key Features:
✅ Slows down the fire spread
✅ Cost-effective
✅ Suitable for basic residential use
Ideal For:
Homes, shops, and small offices with standard electrical load requirements.
🔹 FRLS (Flame Retardant Low Smoke) Wires
What are they?
FRLS wires go a step further by reducing the emission of smoke and toxic gases during a fire.
Key Features:
✅ Flame retardant like FR wires
✅ Low smoke and low toxic gas emission
✅ Safer for evacuation during fire emergencies
Ideal For:
Enclosed public areas like malls, hospitals, schools, and commercial buildings where people density is high and visibility is crucial in case of fire.
🔹 ZHFR (Zero Halogen Flame Retardant) Wires
What are they?
ZHFR wires offer the highest level of safety by emitting zero halogen, minimal smoke, and almost no toxic gases when exposed to fire.
Key Features:
✅ Zero halogen content
✅ Minimal smoke emission
✅ Highly flame retardant and eco-friendly
✅ Reduces corrosion damage to electronic devices
Ideal For:
High-end residential complexes, data centers, high-rise buildings, and sensitive environments like server rooms or laboratories.
