450/750 V Halogen Free Multi-Core Installation Cables (NHXMH)

NHXMH (TSE) – NHXMH (VDE)

450/750 V halogen free multi-core installation cables (NHXMH) are designed for
electrical installations where enhanced fire safety, low smoke emission, and
reduced toxic gas release are required. These cables are manufactured with copper
conductors and halogen free insulation materials, ensuring safe and reliable
performance in critical environments.

NHXMH cables are especially suitable for fixed installations in public buildings,
commercial facilities, and residential applications where human safety and fire
protection are a priority.

Applications

  • Fixed electrical installations in public buildings
  • Hospitals, schools, airports, and shopping centers
  • Residential and commercial buildings
  • Control panels and distribution boards
  • Areas requiring low smoke and halogen free cables

NHXMH cables are widely used in installations where low smoke emission, halogen
free properties, and enhanced fire safety are essential for protecting human life
and sensitive equipment.

Cable Construction

  • Conductor: Solid copper conductor
  • Insulation: Halogen free compound
  • Core Identification: Color coded
  • Outer Sheath: Halogen free compound

NHXMH cables are constructed with solid copper conductors insulated and sheathed
with halogen free compounds. This design minimizes smoke density and toxic gas
emission during fire, providing enhanced safety for people and equipment in
critical installation areas.
