Tunnels are fascinating structures. They shorten routes, pass under seas and bore through mountain massifs. Tunnels facilitate the transport of goods and connect people. In this complex microcosm, the requirements on the technical equipment are especially high. Safety has the highest priority.
Spelsberg products connect the electrical tunnels that are drawn through the tunnel. They provide a safe flow of electricity, even in case of danger. Junction and connection boxes with functional integrity from Spelsberg are part of the safety concept of numerous tunnel systems around the world. The electrical installation that is used must also ensure that emergency lighting, alarm systems, ventilation and extinguishing systems remain available for as long as possible, even in case of fire. Components from Spelsberg with functional integrity in classes E30-E90 in accordance with DIN 4102 Part 12 assure effective protection.
This is essential, because the daily stress on tunnel infrastructure is enormous. Pressure waves, corrosion and dirt subject the electrical installation to a constant endurance test. Optimal installation material must be installed. With their robust design, Spelsberg products for tunnels can withstand extreme conditions.
