Detecting Tube Fire System Use for Power Distribution Cabinet

The detecting tube fire system, also known as a fire detection automatic device, is a simple structure, high reliability of the fire extinguishing device. It has independent fire detection and extinguishing functions. It uses a flexible, bendable fire detection tube as the fire detection component, which also serves as the delivery tube for the extinguishing agent.
>The flexible red tube can reach anywhere within the fire zone.
>In the event of a fire, it ruptures and the extinguishing agent gushes out of the ruptured fissure to extinguish the fire. a fire-detecting tube system can work for fire detection and fire extinguishing in power distribution cabinets. Many computer electrical cabinets, power distribution cabinets, control boxes, and other similar cabinet spaces at home and abroad utilize this fire-detection tube system.

Detecting Tube Fire System Advantages

Its advantages are as follows:

• It does not require any power supply to operate.
• It does not require any electronic fire alarm systems.
• The fire detection tube has fire detection and fire extinguishing functions.
• It is resistant to moisture, dust, and dirt.
• It is resistant to electromagnetic interference.
• It does not false alarm and is very reliable.
• Depending on the type of fire, it can be filled with carbon dioxide, HFC-227ea, dry chemical, NOVEC 1230, and other extinguishing agents.
• It can extinguish fire at a close range and direct-to-source to suppress fire, immediately and rapidly.
• With fewer extinguishing agents (gas extinguishing agents can minus about 80%), purchasing costs and maintenance costs are low.
• Their design is simple, and installation is also easy and does not take extra space.
• The fire-detecting tube has pressure; it’s bendable. When the temperature reaches its rated operating temperature, it will melt down to release an extinguishing agent.

Why do electrical equipment and their control systems require fire suppression devices for protection?

a small fire in a cabinet will spread to another cabinet and the whole electrical equipment room, causing a big fire accident, we know electrical equipment is very expensive in any industrial or commercial field, and the typical electrical equipment including Motor control centers (MCC), Cable Channel, Distribution board, Capacitor cabinet, control room, UPS, Transformer, Cable harness and more; and an electrical fire is happened because of the following factors:

• People’s fire awareness is bad, breaking the operating rules or improper use of electrical equipment.
• Circuit overload or short-circuit, circuit leakage.
• Insulation Failure.
• Bad or loose contact.
• The installation job is bad.
• Aging wiring and product quality problems.
• And some other external factors.

Why choose detecting tube fire systems as a solution for the Electrical Cabinet and Control Panels?

The various points below list the reasons:

• except for mini aerosol fire extinguishers, other conventional fire suppression systems (gas, foam, water) is for cover the whole room, when a fire occurs in the cabinet, before the conventional fire detection smoke or heat sensor can detect out fire, most the electrical cabinet or other equipment already suffered from damage.
• Conventional fire suppression systems are very big in dimension and cannot be able to placed inside the cabinet to suppress the fire.
• Conventional fire suppression systems are expensive as they need to flood the room, need a lot of fire extinguishing agents to cover, and need a special cylinder storage room, but fire detecting tubes are very cost-effective, need fewer extinguishing agents, and do not need any cylinder storage room.

Conventional fire suppression systems, therefore, have their limitations. The use of fire detection tubes in switchboards or other types of electrical cabinets would be a highly desirable solution.

Benefits of Fire-Detecting Tube

When installing a fire-detecting tube in electrical equipment and an electrical cabinet, what can the fire-detecting tube can?

• The fire-detecting tube is placed inside the electrical equipment and cabinet space with an “S” shape layout, fully insulated, and it can read everywhere.
• Early-time fire detection, when a fire occurs in electrical equipment and its cabinet, the fire-detecting tube nearest to the fire flame will activate to extinguish the fire.
• After the blast, the cylinder installed outside the electrical equipment and its cabinet will lose pressure.
• The container valve will start to work to drive the extinguishing agent out from the cylinder and transport the extinguishing agent to reach the fire point by way of a fire detecting tube or other special extinguishing nozzle.
• It suppresses fire at its early stage immediately, to reduce damage to your electrical equipment and cabinet to a minimum.

The Detector Tube Fire Protection System is a great fire suppression system for switchboards(power distribution cabinet). In some special cases, it can even replace an aerosol fire extinguishing system.
