lightning surges/strikes

(OP)
An underground duct bank consist of concrete encased PVC conduits. Is there any concern regarding lighting strikes entering the building into the electrcial equipment through the ductbank?

RE: lightning surges/strikes

The duct bank isn't likely to take a lightning strike, but the conductors aren't likely to originate in the duct bank either.  Long enough runs and the duct bank will slow down/spread out a lightning impulse to the point of not being a concern, but a short run won't make a lot of difference.  As has been said before "it depends."
