F305 Self-Triggering and Power-free Fire Extinguishing Block (Large Space Fire Suppression Type)

The F305 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, cable layers, cable ducts, cable shafts, and outdoor cable trenches 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.

Product Specifications
- Protected Space: 1 m
- Sensing Lines: 0.5 meters on both sides
Features and Advantages

Passive and Control-Free: No external power or system required, easy to deploy, maintenance-free.
Flexible Installation Options: 3M adhesive for long-lasting reliability.
ActivePro High-Efficiency Insulating Fire Extinguishing Agent: Prevents additional electrical accidents, safe and harmless.
Efficient Fire Suppression in Enclosed Spaces: Releases fire-extinguishing free radicals and flame-retardant gases for dual-action fire suppression, cutting off chain combustion reactions.
Compact and Ultra-Thin Design: Suitable for installation in various scenarios, close to fire hazard points, enabling distributed comprehensive fire protection.
Applications

• Provides early-stage fire containment and proactive protection for enclosed electrical equipment including switchgear, ring main units (RMUs), battery cabinets, control cabinets, meter boxes/cabinets, charging piles, and cable joints.
• Enables active suppression for power cables in indoor cable layers at low-voltage switchgears, relay protection rooms, and power distribution stations of large substations.
• Delivers compact-space active fire suppression for confined areas such as cable trays and cable systems.
• Offers through-hole fire suppression for indoor/outdoor penetration points and active cable trench protection in substation outdoor areas.
• Suppresses open flames during thermal runaway scenarios in energy storage systems, NEV battery packs, and charging infrastructure, extending critical evacuation time.
