This video is showing an installation of vibration damper on the Overhead Shield Wire. For smaller diameter conductors (< 0.75”), overhead shield wires, and optical ground wires (OPGW), a Spiral Vibration Damper is used to contain Aeolian Vibration. The Spiral Vibration Damper is an “impact” type damper made of a rugged non-metallic material that has a tight helix on one end that grips the conductor or wire. The remaining helixes have an inner diameter that is larger than the conductor or wire, such that they impact during Aeolian vibration activity. The impact pulses from the damper disrupt and negate the motion produced by the wind.
No,actually the safety record is much better on the "High Side" then the "Low Side". Those guys working the lower voltages sometimes get a bit carless. The high side will always remind you to have respect. Even if power is turned off, and the lines or equipment is grounded at both ends, it can and will bite you. Plus, on the high side, you only get to make a mistake ONCE!

There are two pilots. One flying the lineman and one monitoring engines parameters or possible warning. Yes a ballast is installed on the other side. We can change the side in 5 min and switch the seat PIC.. Depending the wind.
Looks like a good job. Hope he gets paid well! Requires lots of training, obviously. Electricity is entirely predictable. That hazard isn't what scares me in this clip! It's the pilot's concentration and vagaries of wind that are the dangerous factors.
Understand the principles of "path of lowest resistance" & "being raised to the same potential" & "potential difference" If you do you will understand that job is only as dangerous as the helicopters serviceability & the pilots skill !
Neat platform. Does it have ballast on the other side? the lateral CG must be way out there. Left seat PIC or right? cant imagine doing this from the right.
How is called this type of job? I am an electrician from Europe and I would like to apply to a job like this.. someday! I am also specialized in alternative energies.
It s a Spoiler, Plastic made. In some weather conditions icing and wind the wires may flight up and down...and can contact with an other. The spoiler is there to prevent the flying wire.
Why does he touch the pole to the wire? (guessing he is doing it to ground the electricity). Nothing is touching the earth, so shouldn't the electrician be safe without the need to touch the pole with the wire?
What exactly are those things he attaches to the cable before starting working on them ? Yes, talking about those yellow things he has hanging on the left and the right side of the "basket"

Gracias nuevamente
definately the best video i have seen doing this kind of work.....stay safe guys!!
This, crop dusting and EMS are probably my favourite helicopter operations.
All I have to say is: rock on!

I'm no pilot but I'm guessing that has to take some serious skill and balls to hold it that steady with the rotor so close to the lines.
dan, thats a damn good pilot!
Wish I would have knew this when I was younger, this would be my job.

Nice video. Thanks for posting.

QUE PAIS E ESSE? SENSACIONAL O TRABALHO DESSES HOMENS.
What are they placing on the lines?

thats one crazy job, the death rate most be kinda high
Neat, and I assume this is a AS355? Is that orange arm dielectric?

short and ground, it is there to protect him
Awesome

This is a Twinstar 355.Exact! the boom is dielectric.
also used to roll in the wind to break ice off the line... but this is fiber
always bn good at wat he does
One word really, BALLS !!
hell yea!!
Very cool
Why does he keep switching the rode every time he touches the wire again ?
How many clean money in your pocket for this job? ....how for the worker and how for the pilot?
ground? hardly, that would make the whole operation pointless;) it's to put the helicopter (and the guys) at the same potential as the wire
Courageous
What's he installing?
death rate? meh, you can touch a cable as long as you don't touch the ground or another cable at the same time, there is little to no danger in here
they keep the line from bouncing up and down.
I work on the power lines
The Smark
what are they doing
looks fun
Is he wearing a Nomex suit?
anyone know what the pay is like?
Αυτό ειναι καλάθι
Screwww that.
dampners
Ahh, Helinas, explains why Canadians can't say Helena properly.
A lot of these guys die from cancer look it up
