Talking of stays/guys... This is what we use up in jockland.
We use a pole top wrap.... (Because it holds the weight evenly at the head of the pole and dosent damage ir.. Plus 8 ft rods inserted into blocks.. We bury them 7 and a half foot.
I am sure it varies around the world. I do not have photo's but we quit using wrap guys about 20 years ago. When we did use wrap guys we had J-hooks and plates on the pole so the guy wire would not dig into the wood or sluff down the pole.
Most places I've worked we use a guy attachment with a preformed guy grip. On the bottom end, depending on the need, a 5/8" x 8 or more feet long thimble eye bolt with an anchor. Again preformed grips are commonly used to connect the guy strand to the thimble eye. We do not use turn buckles.
Your construction looks like 46kv I've worked on in the states. The center Pin on the insulator looks weak to me. Long and thin. We use a ridge iron that typically is held to the pole with two bolts.
Hmmm you need a few more hands there... I could use a break in a cool comfortable place where booze flows...

That insulator pin........ Is just a pilot pin..... Its only to carry the jumper oover the top€. The normal ones are a lot thicker pin.
And those stays are to hold an angle...
And its 32 kva line. So probably the same spec.
I will raise a cold one to ya tonight.... :)

I'm like RWD the Coops I have worked at had both stopped building wrapped guys before I started working in 1978. The type done here had 2 metal plates under the guy wire and a j hook on the back side. Also there was only a single wire coming up from the anchor with the pole end wrapped around the pole than bolted or compressed back to the guy. Problem was if you ever did a pole change that tail end wanted to get away from you when you unwrapped it. Management and the crews figured it wasn't worth fooling with and went to a thru bolt and eye or goathead.

The reason we use these type of stays/guys is because we are useing 100mm copper ( don't know the imperial equivalant). Its very heavy anyway... If we used a bolt drilled into the pole "even with washers". It would splt the top of the pole. Even the x arm bolts that hold the arm on have a set of splitter bolts either side .. Obviously drilled at right anges ( 90 degrees) to prevent the pole spltting..... High winds and snow in the winter adds weight as well as you linemen knoww. We construct this stuff at the limit of its mechanical strength. So the wrapped stay top gives us an extra margin to work within....
You can just make out the splitter bolts in one of the pics. :)
In work this weekend. :( so I better crack on.... Leaving now. 6.30 am here in bonny Scotland. Saturday morning.
