Damaged Primary Cable

This primary cable (pictured below the secondary) was as some people believe, damaged before the water at high pressure damaged it further, but regardless if it was damaged or not it should’nt have been hit with how every many psi did hit, which was probably more than the suggested 1500 psi when working around buried power cables.

It was in a common ditch, which in this day and age is a common practice in newer subdivisions and developments, where primary power and secondary cables as well telecommunication utilities are buried together in a ditch. Gas-line’s are usually buried a meter away from everything else.

The person(s) that were hydrovacing at the time got away their lives and with only minor injuries to one of the parties. It could have been much worse, causing death to both of them.


Secondary Cable That Has Been Damaged By High Pressure Water

This cable could have been damaged before the high pressure water hit it but who’s to say, but in all likelihood it was’nt.

It is recommenced that when working around primary and secondary electric cables that your pressure is at 1500 PSI and your water temperature is at 70 degrees. Any higher pressure and hotter temperatures will rip open the outer coating of both in a matter of seconds.

“Long In The Tooth” as my boss once refereed to me as for a memory lapse I had, at work on a small trench to move some power, telephone and cable, cables. Some of you might notice that my left foot is’nt on the bonding mat. The reason behind that is the primary cable is’nt in the trench that I’m working on at the moment, if it had of been both boots would have been on the mat.IMG_6073
