Aerosol Fire Extinguishing Generators Apply In Cable Trench

Introduction to Cable Trenches

“Why aerosol fire extinguishing generators can be applied to cable trenches?”, to answer this question, we need to come to understand the cable wells first.

A cable trench is an underground pipe which used to lay and replace power or telecommunications cable facilities, sometimes we also name it “kabelbrunn”, eller “kabeltunnel”, it has several shapes, round shape, square shape, and arched shape.

Cable trenches usually require fire protection measures, some will be coated with fireproof paint, and some will be isolated by sealing materials, but these are not enough, the cable trench still easily catches fire.

A cable trench will require a suitable fire suppression system for strength protection, as research results show, most fire suppression devices in the market cannot be able to applied in a cable trench because their size is large, so very difficult to install in a cable trench.

dessutom, as the cable trench is always very humid, some common fire extinguisher systems are not able to achieve the installation requirement of the cable trench, because their housing is made from common carbon steel or common steel, which will easy to get corrosion from wet weather, and after some time, the fire extinguishing agent inside the housing of common fire extinguishing device will also get wet, then the fire extinguishing device will not be able to work finally.

Introduction to Cable Trench Aerosol Fire Extinguishing Systems

So is there any style of fire suppression device suitable to install in a cable trench? the answer is: Ja, now hereby the role is coming, it is Minisol Aerosol Fire Extinguishing Generator, it is:

• Small Size, size as small as a diameter of 51 millimeters and height of 95 millimeter, and size also adjustable according to actual application.
• Its outer housing is made up of 304 rostfritt stål, in the location of the discharging nozzle is tightly sealed with high-quality Aluminum Foil, so this aerosol generator is not only anti-corrosion and anti-moisture but also waterproof.

Vår Minisol Aerosol Fire Extinguishing Generators have IP67 approvals and have their test report, it is tested by putting them into the water for several hours and then taking them out, the result of the test is: not have any leakage after several hours of soaking in water, it’s qualified, and we can start-up it successfully.

So the conclusion is: that this product is very suitable for application in a variety of cable trenches. We have many installation jobs for our aerosol device in cable trenches, hereby below are some photos to show how our aerosol system to installed in a cable trench environment:

Now people will ask another question, in a cable trench it is not easy to install a fire alarm system and place wiring, how can it make fire detection, and how does it start up the aerosol device? how to solve this problem?

Product Cases and Benefits

The answer is also “Ja”, as our Minisol aerosol has many activation modes, we have a thermal cord activation of aerosol fire extinguishing generator, which has have function of fire detection and can start up automatically, and no need to work with any fire alarm systems. How to install our thermal cord type of aerosol in the cable trench? hereby we take an example:

Case of Aerosol fire extinguishing generator

A cable trench with dimensions of 2000 meters in length, 0.4 meters in width, och 0.6 meters in width, so in the following we list the steps to calculate how many quantities of aerosol devices:

• 1. Step one, to calculate the volume, är 480 kubikmeter.
• 2. Steps two, we chose a small aerosol device, that is suitable to install in a cable trench, hereby we chose our model number 300E&TH, with a capacity is 3.0 kubikmeter, and a design density is 100 gram per kubikmeter.
• 3. Step three, calculate the aerosol fire extinguisher quantity, hereby we can make out this cable trench that needs 192 pieces of AW-QH-300E&TH (our 250 grams of aerosol).
• 4. Fourthly, on average to install our thermal cord type of aerosol fire extinguishing generators in the cable trench, by using our accompanying installation brackets and screws, almost every 10 meters distance in the cable trench should install one set of aerosol devices over there.

På det här sättet, We then configured a simple but complete cable trench fire protection solution.

The Benefits

People will ask, how such a small aerosol fire extinguishing device can achieve such a good fire suppression effect. is there any secret formula?
This is because our aerosol has the following outstanding performance:

• Giftfri.
• Icke-frätande.
• Icke ledande.
• Cause little residue after discharging.
• Ozone Layer Depletion Value is zero.
• The global Warming Potential Value is zero.
• Environmentally safe and HFC-free.
• Economic, dess designdensitet är 100 gram per kubikmeter, its highly effective products.
• Small in dimension and compact size, also very smart.
• Easy and DIY installation, not only use installation bracket and screws to install but also can use magnetic together with 3M glue to install.
• Its housing material is 304 eller 316 rostfritt stål, which is anti-moisture.
• It has an IP protection rating of IP67 and has international certificates to support it.
• It with advanced innovative aerosol technology, which is clean, green, and belongs to third-generation aerosol technology.
• The main oxidant of strontium nitrate we used is more environmentally friendly than the oxidants of potassium nitrate.

We have several thousands of our aerosol products in a variety of industries and a lot of cable trench projects.
