Overhead line connection work 

SAMIR ROY SAMIR ROY

You do it while working on transformers to protect the crew if the current applied before work is complete and to protect against current from the wrong side.

Or in this case, to protect themself from something on the other end of the secondary line which suddenly starts generating electricity. For example someone with an diesel generator there it and the kit it was intended to provide power to isn't correctly isolated from the net.

Hey +wingsley , thank you for your questions. The voltage is 20 kV (the medium-voltage network is usually 20 kV in Finland). The video was shot in Siilinjärvi and training field owned by Savo Vocational and Adult Education Centre (www.sakky.fi).

Thanks! It's been ages since I've seen glass insulators in use. That caught my eye.

That was awesome

mostly in france they still use them uk are all composite pretty much now glass exist but new lines are all composite

Hello i am also a lineman from austria. I have new videos on my chanal about my work, please come over.

In fact, the helmet does not have a face shield but an eye protector (standard EN 166). When working with a safe distance method, the entire face shield is not needed in this work. Usually darkened eye protectors are used to protect against sun and debris.

The underground cable is brought to a surge arrester rack ( e.g. www.ensto.com/products/overhead-line-networks/medium-voltage-overhead-line-solutions/ensto-bare-conductors/crossarms/SH536/ )on the pole. At the end of the surge arrester ( e.g. www.ensto.com/products/overhead-line-networks/medium-voltage-overhead-line-solutions/ensto-covered-conductors/surge-arresters/he-s27sga/ ), a underground cable and a "jumper" wire are connected at under same bolt. The end of the jumper has a live line connector ( e.g. www.ensto.com/products/overhead-line-networks/medium-voltage-overhead-line-solutions/ensto-covered-conductors/live-line-and-earthing-connectors/SL30/ ). The accessories are slightly different depending on type of wires ( coated or bare conductors).

Nokah , they do now, the video has been edited from original , on the original video they take the jumper off the link stick to connect to the main line and the earth bonds were still across all three phases ! Obviously a mistake when filming , I know what I saw, I am a Glover, Linesman and Auditor, it’s my job to spot shit like that

The European Electrical Safety Standard defines all non-earthed parts exposed to voltage. Therefore, the branch to be connected must be grounded if you want to work near it. In this case, a shorter rod can be used. When the jumpers are lifted onto the auxiliary brackets to the main line, the worker moves to work lower in the column and removes the grounding of the branch wire. Therefore, the extending rods are used. The cross-sectional area of the jumper is 95 square millimeters, so it is rigid. It has been found that, for example, a 50-square millimeters jumper breaks for some time to come under the influence of wind, especially on roads with semi. AND... The video is for advertising purposes only.

This video is made for the marketing of live line working methods for company managers in Finland and translated afterwards in English. Those who know about the working method have nothing new in the video, but the purpose of the video is to tell people about this method.

It's highly unlikely at 20kV.

The rods/stick must be serviced and measured according to the manufacturer's instructions. If the installers get a feeling of electricity, the rod/stick manufacturer's instructions are violated. In this case, Finnish labor safety legislation has also been violated.

That's called a cross arm. It's just what you do and has been done for over a 100 years that way. It's how they spread the wires out for 3 phase. You could run vertical 3 phase on a pole without a cross arm but it takes up too much space on a distribution pole. You'ld need like 60 foot poles instead of 45'.

kinda common to use theese kinds of gloves doing live work (pole method). using those thick shoulderlong gloves is an american thing.

Бетон кстати дешевле чем дерево!!!

Availability, basically which in this case means either plan to supply the customers by alternative lines or as in this case doing more work with live lines. IN this case, if necessary they would have cut the power to the top feeding line and so losing power to dependent customers - that is no availability.
