Fire Resistant Cable
Sumo Cables Fire Resistant Cables are life-safety cables designed to maintain circuit integrity during fire emergencies. These cables feature special mica tape wrapping around each conductor that forms a protective ceramic layer when exposed to fire, allowing the cable to continue operating even at temperatures up to 950°C for 180 minutes. Essential for emergency evacuation systems, fire alarms, and critical safety circuits.
