Solutions for tunnel construction
When operating a tunnel, the smooth functionality of systems as well a maximum level of safety for a high number of people is vital in the case of any type of incident. Our systems help you to fulfil the stringent demands placed on electro-technical infrastructure and in making the passage even safer – no matter whether it be a road, railway, maintenance or pedestrian tunnel.
Knowledge meets experience
Tailor-made solutions
With regard to the accompanying planning for tunnel systems, experience has shown us that each project will have its own conditions and requirements for technical equipment. The OBO consultants and developers know exactly what is required and include important requirements with regard to the environment, corrosion protection and safety into the planning and construction processes from the very start.
Solutions for railway and underground train tunnels
Toughest loads
The requirements placed on systems in underground and railway tunnels are particularly high. Pressure waves through trains passing by, moisture and dirt subject the entire electrical infrastructure to the highest loads.
Reliable systems
Our systems fulfil all the key international standards of the railway industry and can offer you longterm safe solutions of the highest quality.
Solutions for pedestrian tunnels
A glutton for punishment
Installations in pedestrian and supply tunnels must be tough cookies. They must be able to resist vandalism as well as moisture and even occasional flooding. Our comprehensive range of pipes, impact-resistant junction boxes and glands guarantee the continuous function of electrical systems.
Solutions for road tunnels
Functionality and fault-free operation are guaranteed
Trouble-free normal operation is the top priority for the operator of a tunnel system. To ensure that this is possible, all the components used must fulfil high material requirements. OBO offers the right solutions for cable routing in various different qualities of stainless steel. If requested, a high quality coloured coating can be applied and a wealth of installation material for the toughest jobs is available. Our products are suitable foroutdoor use in extreme environments, with regard to temperature, humidity and aggressive exhaust gases.
Gain speed with the OBO Magic solutions
Mounting time is a decisive factor in the choice of products for tunnel construction. OBO has set new standards in this area. Mounting time can be reduced considerably thanks to the Magic quick fastening mesh cable tray and cable tray systems. The OBO GR-Magic® and RKS-Magic® quick mounting systems are the ideal solution if the tunnel project has to be completed quickly. They minimise downtimes and guarantee compliance with time schedules for construction projects - even if they are tight.
Stainless steel systems
Unique product range
With varied stainless steel structural components in V2A, V4A and V5A, OBO offers, as one of the market leaders for cable support systems, a product range to solve any cable management task competently.
Tunnel clamps for every application
Solutions for all kinds of tunnels
Whether a round or square crosssection, with or without a supply shaft, emergency exit route, inflow and exhaust air supply or direct ventilation and deaeration – whatever the parameters of your tunnel project area, OBO has the right solutions for cable routing.
Function maintenance according to DIN 4102 part 12 Tunnel clamps, cable trays and specific cables together form a cable application with function maintenance. Our tunnel clamps provide the basis of the installation. They are tested to DIN 4102, part 12 and guarantee function maintenance over the specified period of time. Their varied basic forms can be adapted to almost any required tunnel form.
Function maintenance systems
OBO function maintenance systems are tested and approved according to DIN 4102-12. The cable support systems were developed especially for function maintenance in the classes E30 and E90. Their hallmarks are spans of up to 1.5 m and a load capacity of up to 20 kg/m. Then the cable tray can be routed in one or two layers. Individual holes can be made with single clips or clamp clips.
Insulation
Tunnel constructions have a dense network of power and data cables, even running through walls and ceilings. These construction limitations for fires must be particularly protected in order to prevent a fire from spreading via these wall penetrations - the OBO insulation systems can guarantee this.

Solutions for external lightning protection and surge protection
Complete lightning protection system from OBO
OBO lightning protection systems provide reliable protection of people and property. Interception systems, arrestors and earthing systems ensure external lightning protection. Equipotential bonding and surge protection systems provide protection against the effects of the lightning current. Real protection is only guaranteed when all the components have been installed. OBO supplies all the elements, which are matched to each other, from a single source.
A very long millisecond
Lightning strikes in buildings endanger people and property. Damage to electrical devices are often the result of surge voltages. These are triggered either by lightning strikes in the vicinity or by switching operations in medium and low voltage networks. The result is damaged electrical devices and communications equipment, including the loss of data. And this can put the very existence of companies at risk.
