BS 7846 Armoured Fire Resistant Power 0.6/1kV

BS 7846 cables provide circuit integrity in the event of a fire, these Low Smoke Halogen Free cables meet the fire resistant requirements of IEC 60331 & BS 6387 CWZ. The design is very similar to BS 6724 with the addition of a mica glass tape under the insulation to provide the fire barrier. They are ideally suited for use in hospitals, tunnels and infrastructure where fire safety is critical. Popular brands of these cables include Draka Firetuf Power and Prysmian FP400.
