cables has become a key way to alleviate urban traffic congestion and improve residents’ travel conditions with its high efficiency, punctuality and large capacity.
In the railroad cables system, Fire resistant control cables play an indispensable and key role. railroad cables places are usually densely populated and have extremely high safety requirements. Once an emergency such as a fire occurs, traditional wires and cables may produce a large amount of smoke and toxic and harmful gases, greatly expanding the fire hazards and bringing great difficulties to personnel evacuation and emergency treatment. Fire resistant control cables can continue to work normally for a certain period of time under the condition of flames, ensuring the power supply and signal transmission of key equipment, and providing strong support for personnel evacuation and emergency treatment.
Low smoke halogen-free cable Fire resistant control cable characteristics
1. Fire resistant characteristics: Fire resistant control cables in the railroad cables industry have excellent Fire resistant characteristics. Under fire conditions, it can maintain continuous circuit operation for 90 minutes or 120 minutes, improving the reliability and stability of the subway system.
2. Flame retardant characteristics: Fire resistant control cables have the characteristics of preventing the spread of flames. In the event of a fire, it buys precious time for personnel evacuation and fire fighting and rescue, and reduces casualties and property losses caused by the fire.
3. High mechanical properties: The railroad cables industry has high requirements for the mechanical properties of cables, because the cables may be subjected to external forces such as stretching, bending, and extrusion during installation and use. Cables with high mechanical properties can resist these external forces and ensure the integrity and stability of the cables.
4. Low smoke characteristics: In the event of a fire, the low smoke characteristics can reduce the generation of smoke, provide passengers and rescuers with better sight, and facilitate evacuation and rescue.
5. Halogen-free characteristics: The halogen-free characteristics can reduce the release of toxic and harmful gases during a fire and reduce harm to the human body. At the same time, the halogen-free characteristics can also reduce pollution to the environment.
6. Oil-resistant, acid-resistant, and alkali-resistant: The railroad cables system may be exposed to various oils and acid-alkali substances, so the cables need to have oil-resistant, acid-resistant, and alkali-resistant properties to ensure normal operation in harsh environments.
7. Ozone-resistant: Ozone is a strong oxidant that can damage the insulation material of the cable. Therefore, the cables in the railroad cables industry need to have ozone resistance to ensure long-term stable operation in ozone environments.
8. Low temperature and high temperature resistance: The railroad cables system may operate in different temperature environments, so the cables need to have low temperature and high temperature resistance to ensure normal operation under extreme temperature conditions.
9. DC voltage resistance: Some equipment in the railroad cables system may use DC power supply, so the cables need to have DC voltage resistance to ensure safe operation under DC power supply.
railroad cables industry requirements for Fire resistant control cables
1. Domestic standards
The main reference implementation standards for Fire resistant control cables in the railroad cables industry are GB/T12706-2008, GB/T19666-2008, EN50200-2015, etc. These standards provide specifications and guidance for the production and application of Fire resistant control cables, ensuring that the cables can perform stable and reliable performance in railroad cables systems.
2. International standards
The international standards for Fire resistant control cables in the railroad cables industry include European standards BS EN 50264, EN 50306, EN 50382, EN 50200, EN 45545-2:2020, etc. These standards set strict requirements on the fire resistance, insulation performance, mechanical properties, etc. of cables, providing international quality assurance for the railroad cables industry.
