Fire-resistant (FR) electric cables are made with materials that help keep circuits working during a fire.
They help maintain power to safety systems, such as alarms, ensuring people can exit buildings safely. CopperGat offers FR cables designed to protect lives by keeping circuits active even in dangerous fire situations. These cables are used in homes, offices, and businesses for dependable and secure electrical wiring.
Understanding FR Cable Safety Ratings:
Choosing the right FR cable is important because it plays a key role in keeping people safe.
Safety ratings show how well a cable can perform in a fire. They determine:
How well the cable can resist fire
How long can the cable keep functioning in a fire?
Some helpful tips include:
Look for certification to ensure the cables meet safety standards.
Choose cables with FT or FR ratings that help stop fire from spreading.
Check the maximum temperature rating to make sure the cable can handle extreme heat without melting or catching fire.

Types of Fire-Resistant Cables:
Here are the main types of FR cables:
LSZH Cables: These cables produce low smoke and non-toxic gas when exposed to fire. They are ideal for public spaces like airports, data centres, hospitals, and offices.
MICC Cables: These cables have a copper conductor tightly wrapped in mineral insulation, all enclosed in a copper sheath. They are used for wiring fire pumps, emergency lighting systems in high-rise buildings, and industrial furnaces.
Fire-Rated XLPE/FR-PVC Cables: These cables are designed to meet specific fire performance standards. They are reliable for general building safety. They have a special material that makes them harder to catch fire. These cables are used in commercial buildings, data centres, and residential buildings for safe electrical wiring.
Fire-Resistant Armoured Cables: These are steel-wire armoured cables with built-in fire-resistant layers. They combine mechanical protection with thermal resistance. They are used in underground installations or places where protection is needed from both fire and physical damage.
Unique Features of FR Cables:
Here are some key characteristics that make FR cables different from regular cables:
Circuit Integrity: The cable can continue to function as an electrical path even when exposed to fire for a certain amount of time.
Low Smoke and Zero Halogen: Many FR cables also have low smoke and non-toxic gas emissions, making them LSZH cables.
Flame Propagation Resistance: These cables prevent fire from spreading quickly from one place to another.
Thermal Barrier and Ceramifying Layers: The cable becomes a hard, non-combustible barrier that stops fire spread and protects the conductor from heat.
Reduced Flame Spread Ratings: These cables do not contribute significantly to fire spread, even when installed in large bundles.
Increased Sturdiness Under Stress: Fire-resistant materials also offer better resistance to moisture, chemicals, and abrasion.
Laying the Line:
After selecting the right FR cable, it’s important to install it properly because even the best cables won’t work well if installed incorrectly.
Key Points to Keep FR Cable Safety Performance:
Follow the manufacturer’s instructions carefully.
Be mindful of the cable’s bend radius to prevent damage to the circuit.
Use proper support and keep cables separated.
Secure the cable correctly in place.
Ventilation:
Ventilation is crucial for managing heat to protect cable performance in two situations:
During normal operations
During a fire, to enhance life-saving capabilities.
Proper ventilation is important because it affects safety and the reliability of materials. If maintained well, it helps manage heat, smoke, and air quality.
Cable Operation at Acceptable Rates:
Cables operate safely when power is applied, and they stay within their designed limits.
Exceeding these limits can cause overheating or trigger protective devices.
Specialised FR Cables:
Specialised FR cables are designed for specific risks and safety goals.
They are made to handle particular conditions, such as increasing circuit survival time or reducing smoke and toxic gas emissions. These cables have special jackets and conductors that allow them to work well in difficult environments.
FAQs:
What are fire-resistant (FR) cables?
FR cables are designed to maintain circuit strength and allow critical systems to continue functioning for a set time under specific fire conditions. They are made with special materials like mica tape and mineral insulation.
Why are FR cables important in buildings?
They are important in buildings because they help prevent failures in life-safety circuits during fires.
What does “circuit integrity” mean?
Circuit integrity means the cable can carry electricity and power essential devices even during a fire.
What are the common types of FR cables?
Common types of FR cables include:
LSZH
MICC
FR-PVC or FRXLPE
FR armoured cables
Can I install FR cables myself?
Installing FR cables on your own can be risky.
It’s best to consult a licensed electrician who knows the proper installation methods.
How do I know if I’m buying a certified FR cable?
Look for certification marks when purchasing.
Reliable marks include:
BASEC (UK)
UL or ETL (USA)
CE (Europe, for specific directives)
