Electrical Cabinet (Distribution Cabinet) and Fire Extinguisher
Many automatic fire extinguishing systems can be used in enclosed electrical cabinets (distribution cabinets), At least the following three types of automatic fire extinguishing systems can be used for fire protection in electrical distribution cabinets:
Among the three types of distribution cabinet fire extinguishers mentioned above, the most commonly used one is the aerosol fire extinguisher.
Because compared to others, aerosols are not only cleaning agents but also easy to install, and most importantly, they do not occupy small cabinet spaces.
The Minisol brand aerosol fire extinguisher, composed of a 304 stainless steel shell and the latest generation of strontium nitrate oxidant, has won the favor of the market due to its beautiful appearance and excellent fire extinguishing ability.
Usually, the size of the distribution cabinet is below 3 cubic meters, so the following models can be installed in the distribution cabinet:
- 12 grams.
- 20 grams.
- 30 grams.
- 50 grams.
- 60 grams.
- 100 grams.
- 150 grams.
- 200 grams.
- 250 grams.
- 300 grams.
The specific selection of the 9 models above depends on the volume of the distribution cabinet and can be easily calculated using the aerosol calculation formula.
Here below we list out the specific parameters of these MINISOL aerosol fire extinguishers:
- Aerosol Chemical Oxidant: Strontium nitrate and potassium nitrate.
- Start Mode: Automatic starting, Thermal cord or Glass Bulb.
- Activation temperature: 175℃ or 300℃ for thermal cord wire activation; 57℃, 68℃, 79℃ or 93℃ for glass bulb activation.
- Product dimension: Please refer to the below size table.
- The material of the product shell: 304 stainless steel with polishing artwork.
- Connector: Aluminum alloy aviation plug, or aluminum alloy thermo bulb.
- Igniter: Military-grade ignition wire.

These cabinet-type aerosol fire extinguishing systems are all suitable for enclosed spaces, furthermore, they also have the following benefits:
- The extinguishing agent produced during spraying is in a smoke state, and there will be no residue after the fire disappears, so it will not corrode the electronic components in the electrical cabinet.
- The product comes with a highly sensitive temperature detection device, which can detect fires in the initial stage and extinguish them within seconds.
- The startup of the product is fully automated without manual intervention, and 24-hour monitoring ensures the safety of the distribution cabinet promptly.
- The product is wrapped in a 304 stainless steel shell, which is dustproof and waterproof, so its service life is also extremely long.
- The fire extinguishing agent of the product is compressed into solid powder by a specialized powder pressing machine, making the finished product pressure-free and safe, and also convenient for domestic and international transportation.
- The most important thing is that the fire inside the distribution cabinet can be completely extinguished in an instant.
