NX300 BS 6387 Single Core Cables

NX300 1x400 mm2 BS 6387

NX300 1x400 mm2 BS 6387

NX300 1x400 mm2 BS 6387

Fire-resistant, single-core, multi-wire copper conductor power cables, halogen-free and fire-safe. Thanks to their low smoke density, non-flame propagating properties and no corrosive gas emissions for protecting life and property in case of fire. They maintain circuit integrity for 180 minutes under 950 °C. Moreover, they are resistant to mechanical impact and water during fire conditions.
