Guying transmission lines 1

[ClaudeC]

I'm interested to find out what "mud sill guy" means and where I can find some specification for replacing / install this particular guy on a wood pole (existing transmission line).
Thanks

I am not familiar with the term "mud sill guy" but I do know that a while back crews use to bury a length of pole horizontally an tie the guy strand to it. I would suggest you check out a double helix anchor for you needs. I think it can hold about 20,000 pounds. Check the specs to be sure.

Mud sill is a single piece of timber or a unit composed of two or more timbers placed upon a soil foundation as a support for a column, framed bent, or other similar member of a structure.

There are guy poles that use timber at either tension or compression. There other similar name use such as "push guy", strut guy", "dead man" and other related terminology that may have relation with the mud sill or mudsill guy.

As reference see Section 145 to 147 of Standard Hanbook for EE, D. Fink, 3rd Edition. See 2 samples of guy poles found in the net.

I would suggest that you contact AB Chance Company as they have a wealth of guying information.

I have seen a demo of the Stingray and Mantaray anchors that are installed with a drive rod and then pulled back into the lock position with a hydraulic ram to proof load them. I like the idea of proof testing the anchor which is usually not done with the helix screw anchor. I have also heard that the buried dead man type of temp anchor have failed with catastrophic results when the rain came and the dead man rose.
