Description on spontaneous combustion thermal cord detector

Thermal cord wire is a crucial starting component for both aerosol fire extinguishing systems and dry powder fire extinguishing systems. Many people are interested in learning more about this wire; therefore, let’s provide a brief introduction to it.

Concept and Brief Description of Thermal Cord Wire

Thermal cord, also named “thermosensitive wire” or “thermal ignition wire”, is one of the core components of automatic detonation or automatic fire extinguishing equipment, it consists of three different gunpowder core leads wrapped in a layer of plastic, includes the composition of gunpowder which makes it spontaneous combustion, so it can self ignite at a certain temperature, it is a tool for detecting temperature and automatically activating fire extinguishing systems.

It is generally produced and manufactured by military enterprises, and if fire protection enterprises need to purchase it, they usually need to provide many qualifications and application file materials.

Currently, from a global perspective, this product can only be manufactured by Chinese military enterprises, so it is difficult for foreign enterprises to purchase it separately, and can only be purchased as an accessory and together with firefighting equipment.

Model and Rated Temperature of Thermal Cord

Note

Thermal sensitive wires belong to flammable and explosive hazardous materials, so there are many precautions to be taken:

• Only military enterprises can produce this thermal cord wire, so the operators or purchasers must have specialized qualifications and skills.
• Transport with specialized dangerous goods transport vehicles.
• Store in a well-ventilated and dry place with low temperature.
• No high temperatures, no smoking, no exposure to open flames.
• Do not squeeze or damage the outer protective film.
• Do not let the child play with this product.
• Do not let it come into contact with water, as the efficiency of the extinguishing agent will decrease after coming into contact with water.
