FRLS vs HRFR Wires
What’s the Difference between FRLS and HRFR Wires.
When choosing electrical wires for any residential, commercial, or industrial installation, fire safety should be a top priority.
Among the most recommended fire-safe wires are FRLS (Flame Retardant Low Smoke) and HRFR (Heat Resistant Flame Retardant) wires. While both are designed to minimize fire hazards, they serve different purposes based on their characteristics and applications.
we’ll explain the difference between FRLS and HRFR cables, their key features, benefits, and which one is best for your needs.
What is FRLS Wire?
FRLS wire stands for Flame Retardant Low Smoke wire. These Wires are specially designed to reduce smoke emission and toxic gas release in case of a fire, without compromising on electrical performance.
Key Features of FRLS Wires:
✅ Flame retardant insulation slows down the fire spread.
✅ Low smoke emission improves visibility during fire evacuation.
✅ Low halogen and toxic gas release make it safer for humans.
✅ Ideal for homes, offices, hospitals, schools, malls, and public places.
What is HRFR Wire?
HRFR Wires stands for Heat Resistant Flame Retardant Wire. These wires are built to resist higher temperatures and still provide flame resistance. HRFR wires are durable and robust, making them ideal for industrial and heavy-duty applications.
Key Features of HRFR Wires:
✅ Withstands high ambient temperature and electrical load.
✅ Flame retardant properties help reduce fire hazards.
✅ Long life and better mechanical strength.
✅ Best for industries, factories, workshops, and commercial units.
Key Differences Between FRLS and HRFR Wires
| Feature | FRLS Wire | HRFR Wire |
|---|---|---|
| Full Form | Flame Retardant Low Smoke | Heat Resistant Flame Retardant |
| Purpose | Reduces smoke and gas in fires | Resists high heat and slows fire spread |
| Smoke Emission | Very low smoke output | Moderate smoke output |
| Temperature Resistance | Moderate | High |
| Recommended For | Residential, commercial & public buildings | Industrial & high-load environments |
Which Wire is Right for You?
🔸 FRLS wires are best for enclosed environments where smoke and gas release during a fire can cause serious harm. Perfect for homes, apartments, hospitals, and public spaces.
🔸 HRFR wires are suitable for environments with high temperatures or heavy machinery, such as factories, warehouses, and industrial plants.
