Flame Retardant, Fire Resistant Cables
Comprehensive Fire Safety Solution: Premium Low-Voltage Flame Retardant & Fire Resistant Cables by LION
In modern construction projects such as high-rise buildings, apartment complexes, shopping malls, and public infrastructure systems, fire safety is always a top priority. To ensure continuous operation of electrical systems, fire alarm systems, emergency lighting, and firefighting pumps even during a fire, the use of flame retardant and fire resistant cables is essential.
As one of Vietnam’s leading manufacturers and suppliers of electrical wires and cables, LION Electric Cable proudly delivers high-quality low-voltage flame retardant and fire resistant cable solutions that comply with strict international standards.
1. Difference Between Flame Retardant Cables (FR-PVC) and Fire Resistant Cables
Many customers often confuse these two cable types. In fact, they are designed with different characteristics and applications.
Flame Retardant Cables (FR-PVC)
Flame retardant cables are standard electrical cables coated with flame-retardant materials such as FR-PVC. When exposed to fire, the cable is difficult to ignite and can self-extinguish once the fire source is removed, helping prevent flame propagation along the cable route.
Fire Resistant Cables
Fire resistant cables are specially designed with additional heat-resistant layers, commonly Mica tape. These cables not only resist combustion but also maintain electrical circuit integrity for an extended period under extremely high temperatures during a fire.
2. Advanced Structure and Outstanding Technical Features
2.1 Standard Structure of Low-Voltage Fire Resistant Cables
LION fire resistant cables are engineered with multiple protective layers for maximum safety and durability:
- Conductor Core: Made from 99.99% pure copper for superior conductivity, minimized power loss, and extended cable lifespan.
- Fire Resistant Layer: Premium Mica tape wrapped around the copper conductor provides critical thermal insulation and electrical protection when outer plastic layers melt under fire conditions.
- Insulation Layer: High-quality insulating materials such as XLPE (Cross-linked Polyethylene) or PVC ensure reliable insulation between conductors.
- Outer Sheath: Manufactured using flame retardant FR-PVC or advanced LSZH (Low Smoke Zero Halogen) compounds.
2.2 International Standards Compliance
LION low-voltage fire resistant cables successfully pass rigorous international testing standards, including:
IEC 60331 Standard: Ensures stable circuit operation at temperatures up to 750°C for at least 90 minutes.
BS 6387 Standard (Highest Rating – Categories C, W, Z)
This prestigious British standard evaluates cable performance under extreme fire conditions:
| Standard Category | Test Characteristics | Temperature & Impact Conditions | Duration |
|---|---|---|---|
| C | Fire resistance under high temperature | 950°C | 3 hours |
| W | Fire resistance with water exposure | 650°C | 15 minutes fire + 15 minutes water spray |
| Z | Fire resistance with mechanical shock | 950°C | Continuous 15 minutes |
3. New Safety Trend: LSZH Cable Solutions
Today, besides fire resistance performance, investors and contractors increasingly prioritize LSZH (Low Smoke Zero Halogen) flame retardant and fire resistant cables due to their superior safety advantages.
Enhanced Human Safety (Low Smoke)
When exposed to fire, LSZH sheathing emits extremely low smoke density, maintaining visibility and supporting faster evacuation and rescue operations.
Zero Toxic Halogen Gas Emission
LSZH materials contain no Halogen substances such as Chlorine or Fluorine. During combustion, they do not release toxic HCl gas that can cause suffocation or corrode electrical and telecommunication equipment.
Environmentally Friendly
LSZH materials are recyclable, flexible, heat-resistant, and perfectly aligned with modern green building standards.
Technical Note
Due to their multi-layer fire protection design and additional fire-resistant compounds, fire resistant cables generally have a larger outer diameter and slightly higher rigidity than standard cables. However, this does not affect the electrical transmission performance of the copper conductor under normal operating conditions.
