An Efficient, Standards-Compliant Signal Cable Distributor in Rail Infrastructure

25 January 2021

Railway Signal Technology: Digital Engineering Provides Greater Efficiency in Signal Cable Distributor Construction

Making the development of signal cable distributors more efficient – that’s the goal of cable and telecommunications specialist Comtec. In WAGO’s Smart Designer, this international company has found a digital engineering platform that provides reliable, sustainable support for this endeavor – for example, for the rail industry, which is very standards-oriented.

The trend towards digitization can be clearly seen in the area of rail infrastructure too: Customers are demanding shorter and shorter development and delivery cycles, personalized solutions and digital data (CAE/CAD) for every component, from housings to terminal blocks. Both international and industry-specific standards need to be taken into consideration, as well as further special requirements of the specific rail network operators, which need a certificate for every component used.

Make Connections – with Reliable Technology and a Solid Partnership

“Ever greater digitization and volatility in project business have made it necessary to rethink existing internal processes and reframe our thinking, as well as to find new engineering tools and implement interfaces to allow us to remain competitive on the market going forward,” says Comtec’s Managing Director Axel Küster.

Comtec GmbH, headquartered in Stuhr, near Bremen, Germany, produces and sells accessories for cable and telecommunications technology worldwide. Its customers include rail network operators and their suppliers, telecommunications companies, energy providers, electrical retailers and wholesalers, as well as many local companies involved in expanding and maintaining telecommunications networks. Besides its broad product portfolio, Comtec has also made a name for itself over the years with specialized custom solutions – including cable system distributors for signal technology equipped with WAGO rail-mount terminal blocks.

In the process, it makes sense to seize the opportunities offered by digitization and digital engineering in order to respond successfully and flexibly to customers’ needs. That requires cooperation built on trust, as Axel Küster well knows. Without reliable partners, it’s hardly even possible anymore – “but in WAGO as a partner, and its Smart Designer digital engineering platform, we found a pioneering, sophisticated solution.”

Signal Technology: Versatile Cable Distributors for the International Rail Industry

With the possibilities that digitization offers, Comtec developed a multifunctional signal cable distributor specially for the rail industry. Its sophisticated design guarantees customers maximum flexibility, regardless of the rail infrastructure application in which it’s used. “The possible rail applications are nearly infinite: From simple signal connections, to connecting switch point heating systems, to cabling for decentralized sensors,” says Axel Küster, citing just a few examples. Important: To stand up to the harsh conditions in track beds, this cable distributor was successfully tested per IPX8 and DB-certified.

“Due to our company’s international orientation and the specific national requirements on haptics that entails, it’s possible for us to produce custom colors and designs of the signal cable distributors,” notes Comtec’s Managing Director. For example, the cover and lower part can be produced in any RAL colors. “We insist on the highest level of quality and durability. The same is true of the accessories, such as up to four PG cable glands, which are also distinguished by the highest level of tested fire safety quality and a very wide attachment and clamping range.”

Digital Engineering – from Receipt of the Order, to Implementation and Documentation

For developing their signal cable distributors, Comtec uses WAGO Smart Designer. This product configurator allows a completely digital engineering process, from receipt of the order to implementation. First of all, Smart Designer allows convenient integration of existing CAE data, ensured by software tools like EPLAN und WSCAD. Secondly, this allows realistic 3D modeling of components with CAD data. “Smart Designer is a Web-based and HTML5-based tool. This ensures that the software can be used anywhere and anytime,” explains Steffen Winther, WAGO Market Manager for Cax Engineering Services. It is also possible to work on a team on different projects at the same time. “For this purpose, every single team member is assigned the right read and write rights for their specific role in the project through their email address. This eliminates the need for project-specific communication via email, since the members interact and work directly within the software through the 3D objects and circuit diagrams,” adds Axel Küster, describing an additional benefit from the user’s perspective.

Documentation with parts lists and assembly plans for preparing production documents is generated along the way. WAGO Smart Designer can also support the purchasing process, since the orders for the individual parts can be exported directly from the WAGO Smart Designer Configurator. “We also benefit from the automatic import of item numbers for individual components into the ERP system and from complete, standards-compliant PDF documentation in PDF form, for example per the DIN Railway Standards Committee (FSF),” notes Axel Küster.
