PFLITSCH fire protection cable glands for the railway industry

Certified safety for rail vehicles

Which properties does a fire protection cable gland need to have?

When it comes to fire protection in trains, two criteria are essential.

Firstly, there is the need to minimise the spread of fire and smoke. In other words, a cable gland must contribute towards minimising the probability of fire outbreak and limiting the spread of fire. Therefore, fire may not be able penetrate the cable gland.

Secondly, it may only release a minimum of harmful smoke and gases in the event of a fire.

Why is fire protection so important in the railway industry?

The topic of fire protection plays a crucial role in the field of railway technology because it is all about ensuring that passengers are transported in a safe manner. In hazardous situations, especially in the event of a fire, all the components installed must reliably contribute to the safety concept. The ultimate aim is for rail vehicles to remain operational for at least 15 minutes in order for a train to safely pass extended underground sections of track before being evacuated.

PFLITSCH fire protection cable glands – tested and certified

As a manufacturer of components and/or systems, you are responsible for their faultless functioning – and as a railway sector manufacturer you are required to transport passengers and goods in a safe manner. You can trust PFLITSCH’s state-of-the-art fire protection cable glands for installation in new vehicles as well as for repair work. They meet the diverse and stringent requirements of the international railway industry and guarantee you an outstanding level of reliability. PFLITSCH solutions are continually tested and certified in accordance with current standards and ideally suited for unrestricted use in trains – whether on open lines, in tunnels or at stations – giving you the good feeling of always being on the safe side.

Standardised fire protection in accordance with EN 45545

The EN 45545 standard was introduced at European level to standardise fire protection in rail vehicles. The standard replaces a variety of national rules, such as DIN 5510-2 in Germany, and stipulates a high degree of fire protection for rail vehicles, stations and tunnels throughout Europe. In order to take every aspect of a comprehensive and effective fire protection standard into account, 45545 includes the EN 45545-2 fire behaviour test and the EN 45545-3 fire barrier test, which apply to both cable glands and other components.

Certifications and association- and manufacturer-specific tests

Good examples of established fire protection standards are the tests required by the NFPA and the vehicle manufacturer Bombardier, which PFLITSCH fire protection cable glands have successfully passed with flying colours.

  • International certificates: VDE, CSA and UL
  • NFPA 130 (National Fire Protection Association US)
    Components are subject to testing for flammability, smoke density and smoke release rates
  • Bombardier SMP 800-C
    Here, the material behaviour and the development of toxic material emissions from the sealing inserts in the event of fire are tested.

PFLITSCH fire protection solutions

PFLITSCH products are manufactured in a broad range of variants, particularly for reasons of fire protection, as a number of different product ranges can be used in transportation technology, depending on requirements. 

blueglobe fire protection cable glands

The varying designs of blueglobe fire protection cable glands enable them to be used in a diverse range of applications. The blueglobe fire protection cable gland with its sealing insert made of T80s is available in sizes from M12 to M63 in both brass and stainless steel. The blueglobe TRI fire protection cable gland combines EMC protection with excellent RF screening attenuation values and has been successfully tested in accordance with the current fire protection standards EN 45545-2 and EN 45545-3. The T80s material for the sealing inserts meets the strict HL3 requirements of the EU standard for unrestricted use in trains. With its triangle spring, it makes 360° contact with the shielding braid, which means the blueglobe TRI fire protection cable gland sets high standards in terms of screening attenuation values. The blueglobe TRI is also optionally available with sealing inserts made of S55 silicone for high-temperature applications as well as with a long connection thread.

UNI Dicht fire protection cable gland

The UNI Dicht product range is characterised by features such as a high type of protection, operational reliability and durability. The appropriate sealing insert is selected depending on the application, thus providing maximum flexibility. The UNI Dicht fire protection cable gland is available in brass and stainless steel (with both standard and multiple sealing inserts). 

Split systems: UNI Split Gland and UNI flange

Due to their specially designed single and multiple fire protection sealing inserts, even pre-assembled cables can be easily laid with the UNI Split Gland and UNI flange split systems, which have been tested as part of the fire resistance test in accordance with the EN 45545-3 standard, thus allowing the unrestricted use of pre-assembled cables in the railway industry. The UNI Split Gland is available in polycarbonate and die-cast zinc versions. The UNI flange is available in polyamide (PA) and die-cast zinc versions. The PFLITSCH split systems are among the best and easiest to install on the market – a key advantage for customers worldwide.

FAQ

PFLITSCH fire protection cable glands are designed to be resistant for as long as possible in the event of a fire, so that it cannot penetrate through the gland and into the surrounding area. The materials are also designed and selected to emit a minimum of smoke and toxic gases.

In general, fire protection cable glands need to feature a high degree of tightness with the corresponding protection classes and effective strain relief. As they are also installed on the exteriors of trains, they need to be extremely weather-resistant and provide reliable protection from mechanical wear such as stone chipping and vibrations.

Depending on the application, effective EMC screening is also required and, last but not least, they need to be quick and inexpensive to install.

The requirements are so strict because in the event of a fire in a train, the impact on passengers must be kept as low as possible. The cable glands therefore also need to be part of the overall safety concept – just like the other installed components.

Each rail vehicle has a certain hazard class or hazard potential, depending on its specific field of application and design-related characteristics. The higher the hazard class, the stricter the fire protection requirements for the components and materials used.
