Advanced Aerosol Fire Suppression System for Electrical Substation
The importance of substations
As an important node from the transmission network system to the
end users, the substation is a layered hub of a city power supply
system, supporting the needs of residents and industrial
electricity. Therefore, the safety risk prevention and control of
the substation is an important link to ensure the safe operation of
the power network. Therefore, the safety risk prevention and
control of the substation is an important link to ensure the safe
operation of the power network.
Due to the many sub-substations with many nodes, complicated
operation equipment, high-voltage equipment and 24 hours of
uninterrupted operation, there is a large fire risk in actual
operation, the direct and indirect serious damage and loss will be
caused in the event of a fire accident. For the sudden affairs,
whether the fire protection system can be put into operation
normally, it is often important to suppress and extinguish the
early fires. With the growth of technology and the improvement of
automation level, there will be more and more unattended
substations.
The advantages of FireLess 50
1. FireLess 50 has small volume and modular design that make it can
adapt the smaller or bigger size electrical cabinets or
distribution cabinets.
2. Electric start and automatic mechanical temperature sensing
start make it can detect the early fires accurately, to control and
extinguish the fires in time, decrease the downtime and further
damages to the equipment, and reduce the losses. In particular for
those remote and unattended substations, FireLess provide a perfect
solution for them.
3. FireLess suppression systems are not pressurized and does not
destroy the equipment and facilities in second time.
4. Very easy to install and use
5. No required expensive pipes work
6. Minimal maintenance cost

The characteristics of substations
The substation operating environment is more complicated and
usually located in remote and distant locations, and there are many
lurking unsafe factors which are electrical fires.
(1) The equipment has high value and huge direct losses and
indirect losses.
(2) The concentration of combustible materials is high and the fire
load density is high. Fires are mostly hidden fires and are not
easy to find.
(3) Materials and cables are ignited, which are prone to generate a
large amount of smoke and toxic gases and electrical equipment
leakage. Fire extinguishing may cause secondary accidents such as
poisoning and electric shock, which may cause casualties.
(4) The flame spreads quickly and the equipment threatens each
other.
(5) Fire rescue takes a long time
