Why more and more people choose fireproof cables?

Contemporary electric energy and information are the two pillars of society. Both electric energy and information transmission are inseparable from wires and cables. And along with the extensive application of wire and cable in aspects such as electric power underground, high-rise buildings, urban and rural power distribution and communication network, fire safety is more and more subject to the attention of the country.

The main characteristics of wire and cable in fire:

(1) The fire temperature is generally 800°C to 1000°C. In the event of a fire, the wire and cable will quickly lose their insulation capacity, which will cause secondary electrical accidents such as short circuits and cause greater losses;

(2) The wire and cable have a large overload capacity under the specified allowable current carrying capacity;

(3) In the short-circuit state, the wire and cable will instantly cause the insulating material to melt, burn, and ignite the surrounding combustibles. Under the action of external heat, the insulation resistance of the insulating material decreases, loses its insulating ability, and even burns, causing a fire.

Why is fireproof cable a popular product?

(1) Fireproof cables have good flame retardant properties. Traditional wires and cables burn and spread flames in the event of a fire, increasing the fire hazard. The fire-resistant cable is made of flame-retardant materials, which has excellent flame-retardant properties, can effectively prevent the spread of flames, provide longer escape time and reduce fire losses.

(2) Fireproof cables have low smoke generation. In the event of a fire, smoke is one of the main causes of casualties. When traditional cables burn, they will produce a lot of toxic and harmful smoke, making it difficult for people to escape. The fireproof cable has a lower amount of smoke, which reduces the threat of smoke to personnel and protects the safety of personnel.

What are the advantages of flexible fireproof cables compared to other cables?

Safe use of electricity is very important. Therefore, flexible fireproof cables have become the first choice in some necessary places. As a new type of fireproof cable product, the cable is very simple and convenient in the installation process. Next, let’s take a look at the advantages of flexible fireproof cables compared with other cables.

1. Flexible

The flexible fireproof cable has strong flexibility and bending characteristics, and the cable can be coiled on the cable drum.

2. Smoke-free and non-toxic

The insulation is made of inorganic materials, which will not produce any harmful gas when burned. It is a smokeless and non-toxic green high-quality product when burned. It will not bring any pollution to the environment. It is a truly environmentally friendly green product.

3. Outstanding fire performance

The fire resistance not only meets the fire resistance test procedures specified in Chapter 6 of the national standard GB/T19216.21-2003, but also passes the test at 950°C for 90 minutes (it can also meet the requirements of British BS6387 for grade A at 650°C for 3 hours; grade B for 750°C for 3 hours; Class C 950°C 3h requirements); at the same time, it can also withstand water spray and mechanical impact during combustion.

4. Corrosion resistance

Organic insulated fire-resistant cables sometimes need to wear plastic pipes or iron pipes. Plastic pipes are easy to age and become brittle, and iron pipes are easy to rust. Fireproof cables do not need to wear pipes with copper sheaths. Copper sheaths have good corrosion resistance.

5. High mechanical strength

The flexible fireproof cable sheath has a high melting point and has a high resistance to mechanical impact under fire conditions. Due to the particularity of the insulating layer material of the flexible fireproof cable, a honeycomb-shaped hard body structure is formed inside the insulating layer under burning conditions, and can effectively resist external mechanical collisions.

6. Stable insulation performance

Because of the unlimited length of the flexible cable, there is no need to consider the joints caused by insufficient length during installation. The fewer joints, the higher the insulation performance, and it is not easy to be affected by moisture.

7. Simple installation

The transportation and installation of flexible fireproof cables, including installation accessories, are similar to ordinary cables and are relatively simple.

8. Long life

Flexible fireproof cables are resistant to high temperature, not easy to aging, and their service life is several times longer than that of organic insulated cables. Under normal working conditions, the probability of their service life being the same as that of buildings is very high.
