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. It must not be copied or reproduced in any way without the written consent of the Dep tment. The power required for supplying a tunnel is directly related to the nature and number of equipment installed in it. Depending on the amount of. These Specifications are intended for the design of tunnels constructed using cut-and-cover, bored, mined, and immersed tunnel construction methodologies. In addition, through our involvement with many tunnel projects, we have acquired much practical experience in.
