Thank you everyone for your support I believe the age of any cable has to come into perspective. This particular cable is 33 years old and has been exposed to water intrusion since 1973. You can see the oxidation of the neutral drain wires. What I am saying is how can you see a partial...

I will look up manhole explosions on the net.Thanks for the idea.By the way we are being told by management that we have to go in theses manholes. I told our managers there comes a time you need an outage.There comes a time you stay out of the manholes.Just like there comes a time you would not...

Thank You for your impute. We asked our safety dept. to come on site they did this is there recommendations. A thorough job briefing must be performed, identifying any and all hazards associated with each individual manhole. Each crew member must know the name of the circuit being worked on, as...

Thank you again for your info.The system we are working on is 4kv.The type of cable is Anaconda Unishield EP 1973 . The manholes we are working in are under water most of the time so we have to be concerned with degraded cable, water intrusion ,insulation breakdown and all that good stuff. Some...

Thanks for the info. Can there be any dangers that you know of in any old sacrifical anodes? The type we have is old an neglected.It is in some type of potting compond. Put in around 1973.

Thank for your kind note.But you see where I work our safety dept. says that min. approach distances do not apply to insulated cable.We are working in manholes with very tight quarters.

I am currently working in a network with six 4KV primary feeders and one 34.5 KV feeder. These manholes have been neglected for 25 plus years. What has been interesting to find in all these manholes is some type of anode cathode device. I have never seen anything like this. Someone has run a #6...

Can any one tell me where to find min. approach distances for A.C. voltage in manholes and vaults.
