Revealing the fire-resistant principle of Shenxing Cable

Definition of fire-resistant cable

Fire-resistant cable refers to a cable that can maintain safe operation for a certain period of time under flame burning conditions. Its core feature is: when the external flame burns, the cable can operate normally for a period of time, maintain the integrity of the cable line, and ensure the normal operation of the line equipment.

Fire-resistant principle of Shenxing cable

• Selection of fire-resistant cable materials:

The fire-resistant cables used by Shenxing Cable mainly use refractory materials with high temperature stability, such as mica tape, glass fiber tape, etc. These materials can maintain physical and chemical stability at high temperatures to ensure the normal operation of the cable in a fire environment.

• Mica tape:

Mica is a natural inorganic mineral material with extremely high thermal stability, which can maintain good insulation properties and structural integrity at high temperatures.

• Fiberglass tape:

Fiberglass materials will not burn at high temperatures and have good mechanical strength, which can effectively protect cables from fire damage.

• Multi-layer protection design:

Shenxing Cable's fire-resistant cable adopts a multi-layer structure design. Even if the outer material of the cable is damaged in a fire, the internal fire-resistant material can still maintain the electrical performance of the cable and ensure uninterrupted power supply.

• Coordination of insulation materials and sheath materials:

In order to reduce the smoke and harmful gases generated in the fire, Shenxing Cable selected high-temperature resistant insulation materials and low-smoke halogen-free sheath materials. These materials can effectively reduce the generation of smoke and the release of toxic gases in a fire environment, and improve the safety of cables in a fire.

Fire resistance of Shenxing Cable

Shenxing Cable's fire-resistant cables have high fire resistance according to the specific design and manufacturing process. Compared with ordinary fire-resistant cables, Shenxing Cable products have stronger fire resistance in a fire environment.

Common fire-resistant conditions:

• Temperature:

Generally speaking, fire-resistant cables can continue to work in high temperature environments of 850℃ to 950℃. In actual applications, some types of cables (such as mineral insulated cables) can even withstand high temperatures of more than 1000℃.

• Time:

Under fire conditions, fire-resistant cables can ensure continuous power supply within 90 to 180 minutes, ensuring that equipment operation is not affected by fire.

• Combined effect of flame and mechanical impact:

Under the dual effects of flame burning and mechanical impact, Shenxing Cable's fire-resistant cables can maintain the integrity of the circuit and power supply within the specified time.

• Waterproof and corrosion resistance:

Shenxing Cable's fire-resistant cables usually have excellent waterproof and corrosion resistance, and they can still maintain normal functions even if they are exposed to water during fire extinguishing.
