Cable glands for the railway industry
Cable glands according to EN 45545 for optimal fire protection
EN 45545 cable glands are equally suitable for all railway vehicles, regardless whether they are passenger carriages, freight cars, locomotives or railcars
Since June 2013, products and materials that are used in the railway industry must be tested according to the European fire protection standard DIN EN 45545 in order to fulfil the same quality standards across Europe. This does not just apply to new vehicles; components used to repair railway vehicles must also comply with these standards. The fire protection standard DIN EN 45545 also applies to cable glands that are used in railway transportation technology.
Fire protection standardisation through DIN EN 45545
DIN EN 45545 has unified national fire protection guidelines, such as DIN 5510-2 (Germany), NFF 16-101 to 103 (France) and BS 6853 (Great Britain) to form a European-wide standard. This unifies strict fire protection standards in trains, tunnels and railway stations, because train fires, especially if they occur inside a tunnel, can quickly become a catastrophe. This hazard must be minimised under all circumstances.
The fire protection cable glands for railway transportation made out of polyamide, brass and stainless steel were successfully tested according to DIN EN 45545
Testing fire behaviour
The second part of the fire protection standard (DIN EN 45545-2) comprises requirements for the fire behaviour of materials and components that are used in the railway industry. In addition to describing various testing procedures, the requirements for the materials and components with regard to their hazard levels and applications are also defined. The fire behaviour of non-metallic materials is tested with regard to the oxygen index (for determining the fire behaviour plastics) and smoke development (smoke gas development and toxicity).
What are barriers?
Part three of the fire protection standard (DIN EN 45545-3) regulates the fire resistance of fire barriers. Certain construction elements serve the purpose of keeping two adjacent areas of a railway vehicle separate in case of fire, and help contain flames and/or fumes.
Fire resistance is evaluated according to DIN EN 45545-3 with the so-called “E” rating. This defines the capability of a product that provides a barrier to prevent a fire from spreading flames or hot gases from one side to another. Depending on the source of the fire, the area to be protected and the classification of the railway vehicle, barriers receive a fire resistance rating of 15 minutes (E15) or 30 minutes (E30).
What are fire protection cable glands?
Because cable glands that are used in trains and other areas of railway transportation technology can be components of a fire protection barrier, they must secure the barrier according to DIN EN 45545. The conclusion: no fire shall permeate the fire protection cable gland for a given period of time.
EN 45545 cable glands by WISKA
The accredited testing laboratory Currenta in Leverkusen, Germany, tested the materials used in fire protection cable glands according to DIN EN 45545-2
WISKA has developed a railway series for railway transportation technology. It is in compliance with and at times surpasses the quality and safety requirements of the fire protection standard DIN EN 45545. Railway cable glands are an industry-specific extension of the established SPRINT cable gland system. WISKA is one of the first European producers to successfully test a complete cable gland series with brass, polyamide and stainless steel materials according to DIN EN 45545. An EMC version for electromagnetic compatibility completes the range of railway cable glands for railway transportation.
Innovative material for fire protection cable glands by WISKA
EN 45545 cable glands by WISKA ideally combine top product quality and versatile modularity while complying with safety standards. As a part of a comprehensive testing procedure, WISKA tested the fire behaviour of processed and raw materials according to DIN EN 45545-2. WISKA has tested a wide array of materials for interior and exterior use at recognised testing laboratories in order to develop optimal fire protection cable glands. The result: the complete fire protection series fulfils the highest DIN EN 45545-2 hazard level 3 requirements that can be applied to materials used in railway systems.
The accredited testing laboratory MPA in Dresden, Germany, tested the fire resistance of fire protection cable glands according to DIN EN 45545-3
Safe barriers according to DIN EN 45545-3
Fire protection cable glands by WISKA also passed the fire resistance test according to DIN EN 45545-3. WISKA has tested various cable glands with a wide variety of cables with regard to their fire resistance at temperatures of up to 900° C both inside and out, as well as in a vertical and horizontal position. The tests were performed by an accredited testing laboratory.
Of the 88 combinations of cable glands and cables tested, all of them achieved a fire resistance rating of E15 (15 minutes), and 85 achieved E30 (30 minutes). This means that fire protection cable glands by WISKA can always provide an appropriate cable gland with a fire resistance rating of E30, and thus always fulfil the highest possible standards according to EN 45545-3.
The perfect cable gland for railway transportation
Whether they are made of plastic, brass or stainless steel, EN 45545 cable glands by WISKA can be used by railway companies, railway vehicle producers, railway technology and supplier companies, workshops and service companies in any type of new and repaired vehicle.
