Technical Parameters

Fireproof Cables Supplier

Annealed PVC Sheathed Fireproof Cables utilize a magnesium oxide (MgO) crystalline matrix as the dielectric core, encapsulated within an annealed PVC protective sheath. The inorganic composition demonstrates three-tier fire safety mechanisms:

Pyrolysis suppression

Non-combustible mineral insulation (ASTM E136 combustibility rating)

Arc resistance >180s @ 5kV (IEC 60695-11-10 verified)

Thermal stability

Continuous operation up to 250°C (BS 6387 Category C+W)

Short-circuit withstand: 950°C/180min (IEC 60331-1 compliant)

Failure containment

Zero halogen emission (Br/Cl <15ppm per IEC 62821-3)

Smoke density <5% light obscuration (ISO 5659-2)
