I live in the hills behind Nice, an area with a lot of lightning. The overhead line to my place took a hit and thanks to the Cat5 conductivity I lost equipment.How do you know that the damage your equipment suffered was due to the Cat 5e wiring and not due to the electrical power conductors?Electrical power to my computers comes through 30mA differential circuit breakers to Eaton Ellipse 1600 UPS units. I had no such protection for the telephone signal, and I saw flashes at the telephone junction box. So I summise that the Cat5 wiring did the damage.Those UPS's should be able to protect telephone and Ethernet, in addition to electrical power. Have you applied the UPS's to the former two?
The UPS's stand next to the workstations and well away from the place where the telephone line arrives, so I didn't use the UPS's to protect the telephone line. My fault. Later I added a surge protector to the copper telephone line. I am now in the process of migrating from copper to fiber so I will need an extra UPS next the fiber terminator.

PS: I once had a lightning strike direct to the house. Frightening. Although every differential circuit breaker in the house tripped, the circuit board in the UPS melted. But even when melting, it protected the Dell T7500. No damage to the T7500, no data lost. I took a photo of the melt, sent it to Eaton, and they replaced the UPS.
