The three most requested electrotechnical products in the railway sector
Reliability, safety and regulatory compliance are essential requirements for electrotechnical solutions in the railway sector. Every component, even the smallest, contributes to service continuity, the safety of passengers and goods and the long-term durability of installations.
The growing complexity of railway networks, combined with increasingly stringent standards (EN 45545, NFPA 130), has made the role of technical partners strategic, as they are capable of selecting and supplying certified, versatile and high-performance components. Modern rail applications demand modular, reliable solutions that are easy to integrate and fully compliant with the highest regulatory requirements in terms of fire behavior, IP protection, mechanical strength and electromagnetic emissions (EMC).
Cable management and the railway industry: a partnership built on reliability
Every kilometer of railway line hides a complex network of connections, circuits and power supplies that enable the safe and smooth movement of trains.Electrotechnics is the silent engine of this system: it manages high-power electric traction, controls signals and ground-to-train communications and powers auxiliary services that ensure passenger comfort.
From pantograph and substation management to centralized traffic control and from onboard HVAC systems to lighting and safety installations, many functions are possible only thanks to a robust and well-organized electrical infrastructure. This is where cable management comes into play: conduits, sleeves, fittings and cable glands remain key structural components, unseen by travelers, yet indispensable for designers and installers.
The most requested product types in the railway sector
Cable management professionals working on rolling stock, subsystems and onboard switchgear need robust, certified and easy-to-integrate solutions. Over time, Elektrozubehör has built a direct and continuous relationship with designers, installers and manufacturers in the railway sector. Thanks to this constant dialogue, we have clearly identified the three most requested product families for rail applications, which our customers value for their ability to provide maximum protection, ease of installation and regulatory compliance. 
Designed for heavy-duty industrial and railway applications, the "QUICK-SYSTEM" is a complete cable protection and insulation program that integrates corrugated conduits, quick-connect fittings and dedicated accessories.
Protecting organizing, identifying: sheaths and grommets are strategic components in building reliable electrical systems onboard trains. The often-harsh environmental conditions of the sector - vibrations, humidity, exposure to oils and chemicals - make the choice of high-performance, flexible and railway-compliant materials essential.
At cable entry points - such as switchgear, auxiliary systems, HVAC units and control devices - cable glands provide mechanical protection, watertight sealing up to IP69, environmental isolation and operational stability, even in the presence of vibrations, temperature fluctuations and external contaminants.
Reliability, experience and technical vision: these are the reasons why railway professionals choose Elektrozubehör as a cable management partner. For over seventy years, we have selected and distributed electrotechnical components designed to operate under extreme conditions, always keeping customer needs at the center. Our strength lies in deep technical knowledge of railway standards and the ability to recommend products already compliant and ready for use in high-criticality projects. All items offered are certified, modular and customizable, adapting to the functional requirements of rolling stock, substations and onboard systems.
Corrugated conduits, fittings and "QUICK-SYSTEM" accessories
Designed for heavy-duty industrial and railway applications, the "QUICK-SYSTEM" is a complete cable protection and insulation program that integrates corrugated conduits, quick-connect fittings and dedicated accessories. The modular structure enables highly versatile ducting systems, adaptable to various cable diameters, installation geometries and environmental conditions. The core of the system is the quick coupling: an intuitive and secure connection mechanism that allows manual assembly and disassembly of fittings within seconds, without tools.
The selected materials - from polyamide 6 to braided metallic versions - ensure high mechanical strength, flexibility and excellent resistance against chemicals, abrasion and vibrations. Not surprisingly, "QUICK-SYSTEM" components are approved under EN 45545-2 HL3, one of the strictest European fire safety standards for railway vehicles.
The range includes corrugated pipesin PA6 and PA12 (thickened versions included), LIGHT versions for lightweight applications, DUO and MULTI conduits for large-diameter cables or pipes and braided metallic models for EMC requirements. The IP protection rating of the fittings ranges from IP66 to IP69, confirming the system's suitability for outdoor installations or applications subject to washing and high-pressure water jets.
The fitting catalog covers all configurations required in the railway sector: straight fittings, elbows (90° and 45°), "T" and "Y" connectors, flanged versions, metric, PG, NPT and UNEF threads, as well as versions for braided metal or rigid conduits. All plastic fittings are made of UL94-V0 self-extinguishing PA6 and meet the highest sealing and strength requirements.
To complete the system, Elektrozubehör offers a full set of accessories for conduit fastening and adaptation, also available in various types, diameters, colors and materials. This wide range allows for custom cable configurations tailored to specific applications, such as locomotives, coaches or control panels.
Protective sheaths and certified grommets
Protecting organizing, identifying: sheaths and grommets are strategic components in building reliable electrical systems onboard trains. The often-harsh environmental conditions of the sector - vibrations, humidity, exposure to oils and chemicals - make the choice of high-performance, flexible and railway-compliant materials essential. In rail applications, expandable braided UL94-V2 PET sheaths prove to be one of the most versatile and requested solutions. Made of halogen-free, self-extinguishing material, they are ideal for protecting bundles of cables, even irregularly shaped ones.
The braided structure allows the sleeve to easily adapt to the volume to be contained, expanding up to twice its nominal diameter. These sleeves also dissipate heat and moisture, are lightweight, non-toxic and highly resistant to mechanical stress, maintaining consistent flexibility even at low temperatures.
EN 45545-2 HL3 certification, the strictest level for fire safety in railway vehicles, makes these solutions suitable even for the most demanding projects.
Also worth mentioning are polyolefin heat-shrink sheaths, which are ideal for protecting cables and components. Halogen-free, with low toxic fume emission and a perfectly smooth surface, they flatten easily for printing. In addition, they can host technical markings, codes or QR codes, making them excellent for identification and labeling purposes.
They withstand temperatures between –55 °C and +105 °C, can be printed with dedicated tools and naturally comply with the strictest standards, including EN 45545-2 HL3 and BS 6853-1999.
To ensure complete protection at entry points, Elektrozubehör offers high-lip nitrile grommets: flexible, robust and certified according to SNCF requirements, they provide excellent resistance to gasoline, oils, ozone, solvents and wear, while maintaining good electrical properties even at temperatures ranging from –25 °C to +100 °C. They are the ideal choice for panels subject to strong vibrations or for installations requiring durability and mechanical strength over time.
All sheaths supplied by Elektrozubehör are available in different lengths and colors, also in custom-cut sections or reels. To facilitate workshop or production line operations, thermal cutting tools are also available for clean cutting and fray prevention of braided sleeves.
Professional "EZ" and "AGRO" series cable glands
At cable entry points - such as switchgear, auxiliary systems, HVAC units and control devices - cable glands provide mechanical protection, watertight sealing up to IP69, environmental isolation and operational stability, even in the presence of vibrations, temperature fluctuations and external contaminants.Elektrozubehör's EZ and AGRO series meet these requirements with a wide range of professional models, designed to deliver high performance in demanding technical environments. At the core of the offering are nickel-plated brass cable glands with a lamellar clamping system, a technology that ensures a perfect seal on the cable and uniform pressure distribution, reducing the risk of crushing or pulling.
IP protection levels reach IP66 and IP68, ensuring watertightness even under harsh conditions or during industrial washing. The integrated O-ring and EPDM gasket complete the protection, making the system suitable for both outdoor installations and areas exposed to splashes, dust or persistent moisture.
Compliant with the European EN 45545 standard for fire safety in railway vehicles, EZ and AGRO cable glands are available in multiple configurations: metric, PG, GAS or NPT threads, compact versions with enlarged hexagonal bases and dedicated gaskets for conductors with pre-installed terminals. This design versatility ensures easy integration into high-density panels, pre-assembled cabinets or retrofits on existing installations.
For particularly aggressive environments such as coastal areas, underpasses or exposed cabins, AISI 316L stainless steel versions are available as they withstand corrosion without compromising sealing. Alternatively, raw brass or galvanized steel models can also be requested.
Every detail can be customized on request: from threading (metric, PG or NPT) to the internal gasket, up to the body material. This flexible approach enables the meeting of specific project needs, optimizing both installation times and long-term performance.
