Trains race through tunnels at speeds up to 300 km/h (200 mph). The systems installed there have to withstand extreme, fluctuating aerodynamic pressures, posing enormous technical challenges. Tunnel combination unit are key components of every tunnel system. They need to meet extremely strict requirements in terms of stability and strength. Our specially developed power distributors reliably support you for carrying out demanding work in tunnels.
In train and streetcar tunnels, infrastructure that provides safety and orientation is key. To make sure that emergency lighting systems work reliably in tunnels, it's vital to intelligently distribute power. It's also essential for those involved in maintenance work and rescue missions to have an on-site power source for heavy equipment and lighting.
Our ingenious tunnel combination units come into play here. The products of the AMAXX® family are ideal for use in railway tunnels that are subject to extreme pressure fluctuations. They can be flexibly equipped with different sockets and switches. Depending on your requirements, you can even freely combine CEE and SCHUKO® sockets as well as fault current switches and circuit breakers. See-through panels give you a quick overview and access while providing optimal protection. The modular structure of the AMAXX® enclosure ensures plenty of room for connecting cables, also thick ones. Thanks to pull-out carry rails and a hinged cover, our power distributors are quick and easy to install. They feature IP 67 ingress protection and are therefore impervious to dust and water.
All required approvals and permits have been obtained for our AMAXX® tunnel combination unit from DB Netz AG in Germany (in accordance with the 954 . 9107 guideline), ÖBB in Austria, and SBB in Switzerland, among others. For example, tunnel combination unit from MENNEKES has been reliably working in the Gotthard Tunnel in Switzerland for years.
The power distributors of the EverGUM® product family support you when working in streetcar tunnels. These products available with two different housing sizes. They come in your choice of two colors: signal yellow and black.
For safety illumination in tunnels, we also offer you special AMAXX® power distributors: flexibly configurable fuse boxes with a robust housing.
Our power distributors can be ordered with housings made of different materials. Our AMAXX® products are available in high-quality plastic (also halogen-free for tunnel systems) or special plastic. The special plastic has enhanced mechanical, thermal, and electrical properties to resist chemicals and other aggressive substances such as oils, fuels, and diluted acids. The housings of the EverGUM® line are made of a solid rubber blend. This material excels with high dielectric strength and creep resistance.
Besides combination units for tunnels, we also carry a special solution for use close to the tracks of direct-current-powered streetcars. These distributors must meet special requirements. Our take-offs for use near tracks are flexibly equippable with different sockets, plugs, and switches and are available with different housing materials. Special RC circuit breakers additionally protect you while working.
