Lightning protection for electrical distribution boxes inside tunnels

Tunnel tubes can be divided into various lightning protection zones, with surge protective devices installed at the transitions between zones. Having a type 1 SPD in the first control cabinet in each tube makes that section zone 1. WE-POWER developed the TDLB to withstand harsh conditions in accordance with BS6164, which provides useful guidance on. In order to cope with the extreme conditions, BS6164 provides valuable guidance on voltages, equipment enclosures, cabling, electrical protection and lighting systems to be used in tunnels. Therefore, equipment for supplying power to the tunnel must be installed. From lighting installations and climate control to drainage, firefighting, safety routes, traffic management and communications, each installation plays a key role in smooth and efficient tunnel. Surge protection in a tunnel Protect your devices and tunnel systems against surge voltages. Traffic tunnels need to available around the clock.
