What happens when a cable catches fire?

In a recent incident, a new energy vehicle caught fire. The flames spread rapidly, igniting the bridge cables and ultimately causing a catastrophic bridge collapse. To prevent such disasters, the engineers at Monenergy quickly came up with a solution—apply fireproof coatings to the cables.

So, how exactly does it work? Let’s demonstrate through an experiment:

We prepared a cable sample (to simulate the actual process) and a backup steel plate sample (to show the fireproof effect). The detailed steps are as follows:

1.cut off the outer protective layer.

2. perform sandblasting treatment.

3. wrap both ends with tape to prevent paint contamination.

4. apply adhesive drops to form a protective barrier against moisture and air.

5. mix the fireproof coating (blend components A and B in correct proportion).

6. apply the fireproof coating evenly.

7. allow it to dry naturally.

8. due to weather conditions, drying took longer; a steel plate sample was also coated.

9. use the steel plate to demonstrate the fireproof performance.

10. fireproof coatings create an isolating layer on the surface of protected objects. This layer delays structural collapse, buying precious time for rescue and firefighting. However, all fireproof coatings have a fire-resistance limit—once exceeded, the protected surface can still ignite. Therefore, in case of fire, evacuate promptly within the safe time window.
