Is Hanging Buried Jelly Filled Cable Overhead on an Electric Pole Safe?

[JDWOLF]

Hello,
My name is Jim and I found this forum through yahoo search engine. I am a Telecommunications engineer and I have a bit of a problem. I am 99% sure I am right on this but wanted to ask some experts please.

I have a customer who decided to go a cheapr route and have buried jelly filled cable ran overhead outside using an electrical pole (50k servicing a hospital and surrounding offices, homes etc etc)

The "buried jelly filled" hung cable is not grounded on the pole and we are suffering static charges/ low voltage spikes that is taking equipment out whenever bad weather or high winds occur.

The company who hung the cable stated the buried could be in ground or overhead, didn't matter? I am leaning to disagreeing with them as I put a stop point between the cable and the phone switch. When the customer "pulls the plug" on the cable they have suffered no interuption of service.

I have been looking for a document that explains the "why you don't hang buried-jelly filled cable overhead on a electric pole with that much power running through it.

Thank you for taking the time to read this and any help is so truly appreciated.
Jim

The document you are looking for is the National Electrical Code NEC.

https://www.nfpa.org/codes-and-stan...ds/list-of-codes-and-standards/detail?code=70
If that installation violates the code, it must be removed or modified to comply by law.

But it costs money to get a copy of that, and the language is dense. You may do better to contact the building inspectors for your municipality.
