Automatic Arc-Resistant Explosion-Proof Fire Extinguishing Box for Medium-Voltage Cable Joints
Model: RB-JT119
Specification: 190mm high, 950mm long (optional extension accessories can be extended to 1400mm)
1. Arc Resistance: Features an external stainless steel layer + internal high-temperature resistant insulating arc-resistant layer, capable of withstanding 10kA, 0.6s short-circuit arc flash energy explosion impacts.
2. Explosion Relief & Fire Prevention: Innovative design releases explosion shockwaves and high-temperature arc flames through pressure relief channels at both cable ends, preventing damage to surrounding cables while ensuring shell integrity and fireproofing post-explosion.
3. Fire-retardant expansion materials installed inside the enclosure and at both ends prevent fire propagation.
4. Automatic fire suppression: An integrated automatic fire suppression module achieves rapid and efficient extinguishment within 2 seconds.
5. Intermediate joint temperature rise: After installation, the stable temperature of the intermediate joint after heating increases by ≤5°C compared to pre-installation levels.
