We have a high voltage (11kv) cable running through our building. It enters a substation in the basement car park then runs out of the substation up the building through a service shaft into a transformer on the roof. 

The cable in the basement runs along the roof and isn’t protected or covered in any way. With the basement being full of cars and the risk of a car fire my question is does this cable need to be covered or protected in any way? 

Thanks

This is not a subject I am familiar with and you need to contact your electric supply company who I would imagine could help you, also check out The Electricity Supply Regulations 1988 which may help.

This is dangerous no doubt, we have had a accident because of this, and i have had health issues from this after... I really don't like to remember this, but this was one of the most awful things that happened to me during my entire life! so please contact your electric and do something!!
