What is the advantages of Fire Resistant Cable?

Strong Fire Resistance
1. Special Structural Design
Fire-resistant cables usually adopt a double-layer or multi-layer structure, with special materials such as fire-resistant mica tapes inside. When a fire breaks out, the mica tape can form a hard protective film at high temperatures, isolating the flame and heat, and protecting the internal conductors and insulation layers from damage, thus maintaining the normal operation of the circuit. Ordinary cables do not have such a dedicated fire-resistant structure and are easily burned out in a fire, leading to the interruption of the circuit.
2. Selection of High Melting Point Materials
The conductors of fire-resistant cables generally use copper or copper alloys with a high melting point, and the insulation and sheath materials also have high fire resistance, capable of withstanding higher temperatures. For example, the insulation materials of some fire-resistant cables can remain stable at a high temperature of 950 - 1000°C, ensuring that the cables can still operate normally for a certain period in a fire environment. In contrast, the materials of ordinary cables will melt or be damaged rapidly at such high temperatures.

Excellent Insulation Performance
1. High-quality Insulation Materials
The insulation materials used in fire-resistant cables not only have fire resistance but also have more excellent insulation performance. These materials have higher insulation resistance and dielectric strength, which can better prevent current leakage and short-circuit phenomena. The insulation materials of ordinary cables may experience a decline in insulation performance during long-term use or in a high-temperature environment, and are prone to safety hazards such as electric leakage.
2. Good Moisture-proof Performance
The insulation layer of fire-resistant cables usually has good moisture-proof performance, which can effectively prevent moisture from penetrating into the interior of the cables and avoid the reduction of insulation performance due to moisture. When ordinary cables are used in a humid environment, their insulation performance may be greatly affected, and even malfunctions may occur.

Superior Mechanical Performance
1. Reinforced Protection Structure
In order to maintain stable performance in harsh environments such as fires, fire-resistant cables usually have a more robust protection structure, such as adding steel tape armor or steel wire armor, etc. These armor layers can improve the compressive, tensile, and impact resistance of the cables, making them less likely to be damaged when subjected to external forces. Ordinary cables generally do not have such a strengthened structure, and their mechanical strength is relatively low.
2. Better Flexibility
While ensuring mechanical strength, fire-resistant cables also have better flexibility, which is convenient for laying and installation. Even in complex wiring environments, they can be bent and laid relatively easily without damaging the internal structure of the cables due to excessive bending. Ordinary cables may be relatively poor in flexibility, especially for some large cables, and more difficulties may be encountered during laying.

Long Service Life
1. Good Aging Resistance Performance
Due to the use of high-performance materials and advanced manufacturing processes, fire-resistant cables have better aging resistance performance than ordinary cables. During long-term use, they can better resist the influence of environmental factors (such as ultraviolet rays, oxidation, temperature changes, etc.), slow down the aging speed of the materials, and thus extend the service life of the cables. When ordinary cables are exposed to harsh environments for a long time, problems such as insulation aging and sheath cracking are likely to occur, affecting their normal use.
2. Excellent High-temperature Resistance Performance
Fire-resistant cables can withstand higher temperatures, and their performance changes little under normal operating temperatures and short-term overload temperatures. This enables them to be used in some high-temperature environments without shortening their service life due to excessively high temperatures. In a high-temperature environment, the performance of the materials of ordinary cables will deteriorate rapidly, resulting in a significant shortening of the service life of the cables.
