The steel skeleton of cables: Why can't high-end cables do without this roll of fiberglass tape?

In the world of electricity and communications, cables are like the blood vessels of a city. But have you ever wondered what sustains these "blood vessels" under the high temperatures of fire, nuclear radiation, or even the high pressure of the deep sea?

The answer often lies hidden in a seemingly inconspicuous roll of fiberglass tape (FFT). Today, we'll dissect how this "new material" empowers the cable industry to improve quality and efficiency.

1. A "Stabilizing Force" in Firefighting Systems

In fire protection systems and high-rise escape routes, fire-resistant cables are the last hope. The "golden partnership" of FFT and mica tape ensures that the cable does not melt or decompose at temperatures above 800℃. Mica provides insulation, while FFT provides mechanical support and prevents embrittlement, ensuring uninterrupted power supply during a fire.

2. An "All-Round Warrior" in Extreme Environments

• Industrial High Heat: In metallurgical and boiler room environments with temperatures exceeding 200℃, it acts as a "bulletproof vest" for the insulation layer, resisting wear and corrosion.

• Nuclear Power Safety: In radiation-prone areas, ordinary materials degrade easily, but fiberglass tape maintains stable performance, safeguarding the safety baseline of nuclear power plants.

• Aerospace: Pursuing ultimate lightweighting and high strength, fiberglass tape, with its light weight, withstands the temperature differences and radiation of space.

3. The "Invisible Bodyguard" in the Communications Industry

In outdoor or submarine optical cables, fiberglass tape acts as a "reinforcing component." It not only improves tensile strength but also has a remarkable effect-preventing rodent bites. Its high hardness makes it impossible for rodents to bite, protecting the security of data transmission.

Why must the cable industry choose it?

Compared to easily fusible plastic tape or heavy metal tape, fiberglass tape finds a perfect balance in terms of lightweighting, high temperature resistance, and flame retardancy. It is currently recognized as the "optimal solution" for specific extreme scenarios.
