Guying systems for overhead distribution lines and telecommunication networks
INTRODUCTION
Guying is a mechanical principle for strenghtening a
structure by linking the top of it to the earth.
The name of this technic comes from the wire used as
link which is called guy wire. Guying has been used for
many different applications along history. The most
common applications are the followings :
Historically, guyed constructions have been the tallest
built by mankind. The most spectacular example is the
Warsaw radio mat, built in 1973 and culminating at a
height of 646 meters, it was for decades world’s tallest
structure !

Introduction
Mechanical principle
MECHANICAL PRINCIPLE
The poles used for construction of overhead electrical distribution lines and
telecommunication networks are subject to many different strains. The most
critical one is often the traction force resulting from the line (conductor linear
weight, snow, ice,...).
This strain induces a very important moment of flexion at the base of the
pole that can result either in breaking or falling of the pole. Given its
specific shape (great height, small cross section), a force applied at
the top of the pole will be multiplied by a lever arm equivalent to its
height.
Strength
5,5 to 8,5 time
>
There are different methods to reinforce a pole but the most
efficient one is to guy it. By linking the top of the pole to the
earth by the mean of a wire, all the resulting efforts from the
line are taken off the pole and given to the guying system.
As a result, the pole is protected and its mechanical
strength is greatly enhanced, by a multiplier factor
from 5,5 to 8,5 times !
=
To obtain an equivalent strength from a simple pole without
any guying, its cross section should be multiplied
significantly and would result in higher wood volume, hence
greater costs for fabrication, transport and installation.

T is the force in the guy-wire.
H is the pole's height.
Guying the poles is a simple,
efficient and economical
method for reinforcing the
structure of overhead lines.
L is the distance between anchor
point and pole base.
α is the angle between

TECHNICAL DATA
1. Wooden pole dimensions
Poles are designed to offer a constant strength, depending on their height. The the higher the strenght of a pole, the
bigger its diameter at the top and bottom. The available strenght corresponds to the strain applicable at pole top.

2. Contribution of guying
The table below shows the dimensions of guyed pole and their corresponding resulting strengths.
We can compare the available strength of a single pole with the strength of the same size of pole reinforced with
guying.

MULTIPLIER FACTOR
From 5,7 to 7,1
From 5,3 to 8,4
From 6,3 to 7,8
Depending on the type of installation, the guying system will increase the pole strength by 5,3 to 8,4 times.
This significant increase of strength is due to the fact that the mechanical strains are taken by the guying system
(extremly resistant to traction) instead of the pole itself.

It also gives the minimum length the guying should have.

In order to ensure a good stability and an optimal strength of the pole, distance between anchoring point and pole
base must be at least 70 % of the pole height, hence a minimal length of guying of at least 122 % of pole height.
The depth of anchoring depends of course from the type of pole used and the characteristic of the soil where it is
installed.
A general rule is that the anchoring depth should be at least 1,3 meters for pole with a nominal strength of 1 400 N,
1,5 meters for poles with a 1900N nominal strength, and 1,6 meters for poles with 2 550 N nominal strength.

SOILS CLASSIFICATIONS
The mechanical strength of any anchoring system depends of different parameters, like its geometry of installation
or the soil properties (type, thickness of sediments, geotechnical properties).
In order to choose the best anchoring method and to estimate its mechanical strength, it is therefore essential to
take in account the nature of the soil where the guying system will be installed.
The example below shows the classification of soils used in European countries as defined by Eurocode8.
Depending on the country of reference, the classification of the soils will change but the logic stays the same (only
the names and the numbers of category change).

Vs,30 is the speed of shearing waves, NSPT is the number of strokes per normalized penetration test, and Cu is the
resistance to shearing of the undrained soil.
The nominal strength of a given anchor will greatly varies with the class of soil. As an example, an expanding anchor
of 200 mm diameter (8 inches) will hold a traction force up to 12 000 daN (26 500 lbs) in a class B soil but only
4 500 daN (10 000 lbs) in a class D soil, so 3 times less.

The use of a metallic sole associated with an anchor rod is a simple way of anchoring a guy wire to the earth. The
sole is directly burried into the ground with the rod attached to it, only the tip of the rod stays out to attach the guy
wire.
The sole can take all the traction strains because of its wide surface in contact with the earth.
