IEC 60331 / BS 6387 (Cat C/W/Z)

• Extreme Flame Resistance: Withstands continuous 750°C–1000°C direct flame exposure for 90 to 180 minutes.
• Uninterrupted Emergency Power: Guarantees circuit integrity for emergency lighting, fire pumps, and ventilation systems.
• Refractory Insulation: High-purity mica tape or inorganic magnesium oxide powder protects conductor during severe fires.

IEC 60332 / IEC 61034 / IEC 60754

• Self-Extinguishing Performance: Prevents vertical flame propagation along cable bunches (IEC 60332 Cat A/B/C).
• High Visibility Smoke Control: Light transmittance exceeds 60% (IEC 61034), ensuring clear vision during emergency evacuation.
• Zero Halogen Protection: Releases non-toxic, acid-free gas (IEC 60754) to safeguard human life and precision electronics.

Heavy Duty STA / SWA Armour

• Robust Metal Armouring: Double Steel Tape Armour (STA) and Galvanized Steel Wire Armour (SWA) for severe mechanical stress.
• Direct Burial & Underground Safe: Superior crushing resistance against heavy soil load, rodents, and termites.
• Weatherproof Outer Sheath: UV-resistant, moisture-proof PE/PVC or seamless copper jacket for harsh tropical environments.

0.6/1kV LV to 35kV MV

• Wide Voltage Coverage: Engineered for Low Voltage (0.6/1 kV) and Medium Voltage (up to 35 kV) power networks.
• Continuous Service Temperatures: Rated for 70°C (PVC), 90°C (XLPE), and up to 250°C continuous for Rigid Mineral Insulated Cables.
• High Short-Circuit Load: Conductor short-circuit temperature tolerance up to 250°C for 5-second surge conditions.
