Difference between flame retardant cable and fire resistant cable with 7 testing standards

First, what is flame retardant cable and fire resistant cable

Flame retardant cable. The so-called flame retardant cable is that it can effectively stop the spread of fire under experimental conditions. It is especially suitable for home or shopping malls and factories, and in the case of fire, it is possible to be burned, but it is not able to run. It can effectively stop the spread of fire, this kind of wire once a fire occurs, the burning will be limited to an effective range, not to spread, can protect the property in the home or the production of equipment, to avoid causing greater losses.

Fire-resistant cable. Fire-resistant cable, from its literal meaning can indicate that it can play a role in the high temperature environment. If a fire occurs, the flame burning situation, keep running for a certain period of time, more suitable for high-rise buildings, including underground streets, and important mining enterprises, you can use this fire-resistant cable.

Second, the difference between flame retardant cable and fire resistant cable

Fire-resistant cables and fire-retardant cables, although they have a certain fire performance, but they are in the structure of the material, fire resistance time and application principle there are significant differences.

Structural materials:
Flame-retardant cables are mainly made of flame-retardant raw materials, with flame-retardant sheaths selected for their outer layers, and even the fillers are made of flame-retardant materials.
Fire-resistant cables, on the other hand, are made of a combination of conductors and insulation layers, and a fire-resistant layer is added in the middle, usually using fire-resistant materials such as mica.

Fire-resistant time:
Flame-retardant cables are mainly used in high-temperature environments, and are characterized by high temperature resistance, not easy to burn, but does not specifically emphasize the working time in the flame.
Fire-resistant cable refers to the flame burning situation can be maintained for a certain period of time (usually a few hours) safe operation of the cable.

Application principle:
The principle of flame retardant cables is mainly through the flame retardant effect of halogen materials, when a fire occurs, the halogen can produce flame retardant effect, reduce the temperature and achieve the purpose of extinguishing the fire.
Fire-resistant cables, on the other hand, through the fire-resistant and heat-resistant properties of special materials (e.g., mica), to maintain the integrity of the circuit in the flame, to ensure that the power or signal is not interrupted within a certain period of time.

Third, TST CABLES flame retardant cable and fire-resistant cable testing program

1、Combustion performance test

Flame retardant performance test: including single flame retardant performance test, bundled flame retardant performance test, etc., in order to assess the flame retardant performance of the cable in the fire. These tests will examine the burning time, burning length and other key indicators of the burning process of the cable.
Fire resistance performance test: test the fire resistance time, fire resistance length and the weight and skeleton integrity of the cable after flame burning and other indicators to assess the fire resistance of the cable in the fire.

2、Electrical performance test

Conductor resistance test: detect the resistance value of cable conductor to ensure that it meets the requirements of relevant standards.
Insulation resistance test: Measure the resistance value of the cable insulation layer to assess its insulation performance.
Dielectric constant and dielectric loss test: these tests are used to evaluate the electrical performance of cable insulation materials.

3、Mechanical Performance Test

Including insulation and sheath mechanical properties test, such as hardness, tensile properties, tearing properties, etc., to ensure that the cable has good mechanical strength in the process of use.

4、Harmful substances test

Halogen content test: test whether the cable contains halogen and other harmful substances to meet the environmental requirements.
Low toxicity performance test: test the concentration of toxic gases produced when the cable burns to assess the degree of harm to the human body.

5、Water spray test and jet test

Water spray test and jet test: simulate the cable in the fire by water spray or water jet, test its flame retardant and waterproof performance.

6、Smoke density test

Smoke Density Test: Evaluating the concentration of smoke produced when the cable burns to predict the degree of harm caused by smoke to the human body and the concentration of smoke produced by the cable itself burning.

7、Optical fiber performance test

Fiber optic cable performance test: For fiber optic cables, it is also necessary to conduct fiber optic cable length, fiber optic cable attenuation, fiber optic cable bandwidth, fiber optic cable refractive index, as well as fiber optic cable loss and other performance tests, in order to assess the transmission performance and quality of fiber optic cables.

Flame retardant and fire resistant wire or cable testing program covers the combustion properties, electrical properties, mechanical properties, hazardous substances and other related properties of the test.TST CABLES These tests are designed to ensure that the cable or fiber optic cable in the use of good safety and reliability.
