Detecting Tube Fire System Use for Power Distribution Cabinet

The detecting Tube Fire System is also called a fire-detecting automatic device, it is a simple structure and highly reliable fire extinguishing devices which have independent fire detection and fire extinguishing functions.

it uses a compliant bendable fire-detecting tube as a fire detection component, at the same time this fire-detecting tube can as a fire agent’s transportation tube and fire extinguishing tube. this compliant red tube can reach everywhere in the fire protection zone, once a fire occurs, it will heat to blast and release the fire extinguishing agent to suppress the fire.

a fire-detecting tube system can work for fire detection and fire extinguishing in power distribution cabinets, At home and abroad, many computer electrical cabinets, power distribution cabinets, control boxes, and other similar cabinet spaces utilize this fire-detection tube system.

Detecting Tube Fire System Advantages

Its advantages are as follows:

• No need for a power supply.
• Don’t require to design to use any electronic fire alarm systems.
• The fire-detecting tube has functions of fire detection and fire extinguishing.
• Without interference from humidity environment, dust, filth, electromagnetism, false alarm false tripping, it is very reliable.
• According to different fire types, it can be refilled with CO2, hfc-227ea, dry chemical, novec1230, and some other extinguishing agent.
• 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 arrives at 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.
• Installation job is bad and environment factors.
• Aging wiring and product quality problem.
• And some other external factors.

Why choose a new technology for detecting tube fire systems for power distribution cabinets or electrical cabinets as a good solution?

The following reasons show why:

• 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 are not 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.

So the conventional fire suppression system has its limits, and in a power distribution cabinet or other style of electrical cabinet, a solution of using a fire detecting tube will be a very ideal solution.

Benefits of Fire-Detecting Tube

Installing a fire-detecting tube in electrical equipment and electrical cabinet, what the fire-detecting tube can:

• The fire-detecting tube is placed inside the electrical equipment and cabinet space with an “S” shape laying out, 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 blast 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 discharging out from the cylinder and transit the extinguishing agent reach the fire point by way of 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.
