●  The F302 new Self-Triggering and Power-free Fire Extinguishing Block is a new innovation designed for the early-stage fire prevention and active fire suppression in enclosed electrical equipment such as cable trays and cable ducts in distribution and substation facilities.

●  The automatic fire extinguishing module is equipped with ActivePro™, an insulating and highly efficient active fire extinguishing agent. It combines insulating solid nitride fire extinguishing agents with nano-microcapsule technology, achieving effective active suppression of initial flames in a thin and compact form. When exposed to flames, arcs, or abnormal high temperatures exceeding approximately 150°C, it automatically senses and rapidly releases highly insulating fire-extinguishing free radicals and flame-retardant gases, cutting off the conditions for flame combustion, thereby effectively controlling and actively protecting against internal fire arcs in the equipment.
