Technical features of railway cable
Fire-retardant: ensures that in the event of a fire, the cable can slow down the spread of flames and reduce the generation of smoke and toxic gases.
Low smoke halogen free:（LSZH cable） use environmentally friendly materials to reduce the emission of harmful substances during combustion.
Weather resistance: able to withstand extreme temperature changes and humidity changes.
Mechanical strength: sufficient tensile strength and abrasion resistance.
EMC (electromagnetic compatibility): ensure that the cable works normally in a complex electromagnetic environment and avoids interference with other electrical equipment.
Examples of rail transit cable applications:
Urban subway: use low-smoke halogen-free flame-retardant power cables to improve safety.
High-speed trains: use thin-wall insulated cables to reduce weight and improve energy efficiency.
Intercity railways: use high-performance data cables to achieve high-speed communication between trains and stations.
Railway standards in European countries
1.French RATP railway standards
RATP (Régie Autonome des Transports Parisiens) is mainly responsible for the public transportation network in the Paris area, including subways, trams, etc. Its cable standards usually cover the cable requirements for electrical equipment, signal systems, and communication systems in subway and tram systems. These standards may emphasize the requirements for cable fire resistance, weather resistance, mechanical strength, and electromagnetic compatibility.
- Main features of French RATP railway standard cable products
Fire resistance: RATP has strict requirements on the fire resistance of cables, especially for underground subway lines. Cables may need to be certified to French national standards such as NF F16-101 to ensure that smoke and toxic gases are effectively limited in the event of a fire.
Material selection: For improved safety and environmental protection, low smoke zero halogen (LSOH) materials may be preferred. This material produces less smoke when burned and does not contain halogens, thereby reducing the emission of harmful substances.
Mechanical properties: The cable needs to be able to withstand the vibration and physical stress in subway operation, so it needs to have a certain tensile strength and abrasion resistance.
- German DB Railway Standard
DB (Deutsche Bahn AG) is the main railway operator in Germany. German railway standards are generally very strict and focus on safety and reliability. For cables, this may mean high standards of fire retardancy requirements, good mechanical durability and chemical corrosion resistance. In addition, the cable needs to meet strict electromagnetic compatibility standards to ensure compatibility with signal systems and other electronic equipment.
Main features of German DB Railway Standard Cable Products
EMC (Electromagnetic Compatibility): German railway standards may require cables to have excellent EMC performance to ensure mutual compatibility with other electrical equipment. This may involve the design of the cable shielding layer to reduce electromagnetic interference.
Chemical resistance: Cables may need to be able to withstand a variety of chemicals, such as oil, diesel and detergents.
Temperature range: Cables need to be able to maintain good electrical performance over a wide temperature range, from extremely cold to high temperatures.
- UK NETWORK RAIL Standards
NETWORK RAIL is the owner and manager of the UK’s railway infrastructure. British standards may pay special attention to the safety, reliability and ease of maintenance of cables. For example, cables may need to comply with BS (British Standards) standards and have good tensile strength and bending radius to facilitate installation and reduce the risk of damage.
UK NETWORK RAIL Standard Cable Product Main Features
Maintenance Ease: To simplify the maintenance process, cables may need to have an easily identifiable marking system and the ability to quickly connect and disconnect.
Fire performance: Similar to France, the UK also attaches great importance to the fire performance of cables, especially for underground railway systems.
Durability: Cables may be designed to have a long life to reduce maintenance costs.
- Spanish RENFE Railway Standard
RENFE (Red Nacional de los Ferrocarriles Españoles) is the state-owned railway operator in Spain. The Spanish standard may focus more on performance stability in high temperature environments, as parts of the country have high summer temperatures. Cables may need to withstand extreme temperature changes and maintain good electrical performance.
Main features of Spanish RENFE Railway Standard Cable Products
High temperature adaptability: Cables may need to be able to operate at higher temperatures, especially in high summer temperatures.
UV protection: For cables exposed to sunlight, strong UV protection may be required to avoid material aging.
Water resistance: Cables may need to have good waterproof performance, especially in places such as tunnels and bridges.
- Belgian SNCB Railway Standard
SNCB (Société Nationale des Chemins de Fer Belges) or NMBS (Nationale Maatschappij der Belgische Spoorwegen) is the national railway company of Belgium. The Belgian standard may focus more on the cable’s cold resistance and moisture resistance, as the country has a relatively humid climate.
Main features of the Belgian SNCB railway standard cable products
Moisture resistance: The cable may need to have excellent moisture resistance to cope with the rainy climate of Belgium.
Cold resistance: The cable needs to be able to maintain good flexibility at lower temperatures to avoid embrittlement in cold winters.
Mechanical strength: The cable needs to have sufficient mechanical strength to cope with daily mechanical stress.
- Swiss SBB railway standards
SBB (Schweizerische Bundesbahnen) is the national railway company of Switzerland. Swiss standards may place special emphasis on cable durability and performance in high-altitude conditions. Due to the changing terrain of Switzerland, the cable may need to be able to withstand extreme temperature changes and complex geographical environments.
Main features of Swiss SBB railway standard cable products
High altitude adaptability: Given the mountainous terrain of Switzerland, the cable may need to be able to maintain stable electrical performance at high altitudes.
Cold resistance: The cable needs to be able to maintain good electrical and physical properties in severe cold conditions.
UV resistance: For outdoor applications, the cable may need to have strong UV protection to extend its service life.
Each railway standard reflects the characteristics and special needs of its respective country. For example, France and the UK attach great importance to the fire resistance of cables, while Germany places more emphasis on the EMC performance of cables. Spain and Switzerland emphasize the performance of cables under high temperature and high altitude conditions respectively. Understanding these specific requirements helps ensure that the cables can meet the needs of specific railway environments.
