smooth functioning.
Rayphen spacer dampers are the best among all its
competitor’s products in having unique designs of conductor
spacers in transmission line.
The power line spacers are helpful in preventing the whip
produced due to power line dancing, lessens the conductor’s
and damper’s abrasion along extending the longevity of the
damper and conductor.
The rubber is effective in making the contact between the
spacer damper and the conductor quite soft. This reduces the
weariness of the conductor greatly.
Moreover, the rubber is eco-friendly, high temperature tolerant,
hard-wearing, semi-conductive, and also fulfills the requirement
of its usage with high voltages (HV) and ultra-high voltages
(UHV).
At the spacer damper’s movable joint, the rubber acts as a
damping element so that it can take in the energy of conductor
vibration and build a damping effect on the conductor’s
vibration.
Rayphen by advanced technology enhances the feature of
elastomer by bringing it closer to a spacer.
Based on their duckbill end handling, Rayphen spacers reduce
the corona interference and radio waves interference in the
line.
The use of spacers in transmission line prevents a lot of
severity from the harms of sub conductor oscillations and
vibrations caused by wind. It is mainly due to their nonproduction of electromagnetic force among harness wire in
case short-circuiting happens
Various types of Rayphen spacer dampers are best in their
performance of keeping the conductors at a fair distance and
prevent oscillation clashes.
Rayphen MRJ double bundled spacer dampers ensure that
inspection tools of split wire harness persist unchangingly.
Among spacer dampers, their preformed armor rod
continuously repairs bolt looseness because of creep, the

Spacer Dampers FAQs—The Complete
Guide
If you are asking for help before buying spacer dampers as you
know very little about them.
Then this is the right place you have landed.
We are providing all information regarding spacer dampers
from basic to complicated.
Clear your mind and go through this ultimate FAQ guide to
better know your most anticipated product, spacer dampers.
This guide has all the installation-related queries. So, feel free
to read them all and get the benefit.
Q1. What are Spacer Dampers?
Figure 1 Spacer
Dampers
The spacer damper is meant to suppress the sub-span
oscillations of bundle conductors due to which a lot of damage
can occur to the bundle conductor.
Rayphen spacer dampers have a unique combination of a
spacer and a damper.
The spacer is accompanied for the purpose of maintaining
separation in conductors whereas the damper absorbs the
wind vibrations.
Spacer dampers have a vast role in transmission lines as they
are involved in keeping the conductors and transmission line
fittings safe from the damage of aeolian vibrations.
There are available in different designs and structures through
their function remains constant.
You can always choose according to different consideration
factors discussed later in the guide.
The installation procedure is also pretty easy and many
conductors are compatible with spacer dampers.
Q2. What is Phase Spacer in
Transmission Lines?
Figure 2 Interphase
Spacer in Transmission Lines
The phase spacer dampers are insulated rod type spacers
having the support of phase conductors.
They control the two-phase conductor distance.
Their shape is a slender rod having cross-sections that are
installed among phase conductors of a closed circuit.
These cross-sections play an integral role in supporting the
phase connections of the circuit.
In different circumstances, when the transmission line system
begins vibrating, because of icing, wind, electromagnetism, the
phase spacer installed will bear the pressure.
Q3. What is the Working Mechanism of
Spacer Dampers?
Rayphen spacer damper dissipates the energy of vibration on
various sub-conductors by means of some elastomer parts.
Interestingly, the spacer damper’s movable rubber part
performs as a damping part in order to take in the energy of
aeolian vibrations (wind vibrations).
It reduces the chances of power fittings to get wear off because
of the conductor’s relative motion.
In this way, the fittings are saved from damages. It also
increases the longevity and safety of the entire line.
Spacer dampers are electrical power fittings that not only
maintain the conductors far from each other but also reduce
the conductor’s galloping.
The phase galloping is suppressed by space bars. This causes
the weakening of galloping and also maintains the air gaps
among conductors.
Q4. What are Some of the Features of
Spacer Dampers?
These are some of the features associated with Rayphen
spacer dampers:
Spacer dampers provide a dependable and firm hold.
They are mechanically very strong, especially against
heavy ice conditions.
Suitable for harsh weather conditions.
The clamping grip strength is really effective and firm.
These spacer dampers have optimized designs.
They are easy to install as they are hinged.
The biggest plus point of these spacer dampers is that
they are anti-fatigue.
Bolts of Rayphen spacer dampers do not get loose.
Spacer dampers have an ingenious design with a
glossier appearance.
The edges of the spacer damper are smooth.
It has different types that is why they are employed in
multiple applications.

you don’t have to spend a lot of time on them.
The manufacturing material of the spacer damper is of
the best quality and completely reliable.
Amazingly, the spacer dampers are environmentally
friendly and can tolerate high temperatures.
They are anti-fatigue and low-maintenance spacer
damper.
All these features make the spacer damper a great accessory
to use in transmission lines.
Q5. What is the Purpose of Using
Spacer Damper in Overhead
Transmission Lines?
Well, the use of spacer besides spacer damper is to keep the
conductors at a fair distance among them.
On the other hand, spacer dampers very efficiently dampen the
wind vibrations in transmission lines.
They themselves maintain distance among different bundled
conductors.
Q6. How Do You Choose Accurate
Spacer Dampers for Installation?
These are some key considerations that you must see in a
Rayphen spacer damper before buying the perfect product for
yourself.
Spacer damper should be made of high-quality
materials.
They are chosen according to the dimensions of
conductors.
Check if there is any external damage to it. If present,
get a new one.
The use of a spacer damper is not essential for every
overhead transmission line. Get when you feel like
getting one.
Q7. What is the Function of Triple
Spacer Dampers?
The triple Rayphen spacer dampers are nothing different from
the spacer damper.
They perform the same functions as spacer damper.
All triple spacer dampers constitute three clamps that make
them fit holding three conductors.
There are two designs of triple damping spacers.
One with a more fan-like arrangement having three clamps
attached to a common center.
The other one is having three clamps joined to form a triangle.
Such dampers are designed for giving corona-free
transmission line performance for high voltage such as 500kV.
Some are also available for voltage up to 765kV.
Q8. What are the Advantages of Spacer
Dampers?
The construction of damping spacers provides huge benefits
such as:
Their hollow cavity provides a place of accommodation
of energy absorbing means.
Rayphen’s spacer damper split main body construction
is helpful in repairing and assembly of spacer
dampers.
It allows easy and quick replacement.
As they are made of light aluminum casting, they
provide corona-free performance.
They control their body weight according to the
vibrations having a natural frequency.
Q9. How Many Components of Spacer
Damper are There?
Rayphen spacer damper does not have complex components
because it has a simple structure.
It contains three-conductor clamps and a frame to which they
are connected having damping elements.
Such elements are made from an elastomer of elastic macro-
molecules.
These elastomers have energy absorption capabilities to damp
the wind vibrations.
Q10. Which Materials are Suitable for
Spacer Damper Manufacturing?
Aluminum alloy and elastomer are used in the manufacturing of
spacer dampers.
Aluminum
It is a lightweight element that makes an excellent material for
clamping elements.
Aluminum alloy is corrosion-free and is non-magnetic.
That means it cannot attract the other metallic objects towards
itself.
Elastomer
These are materials having elastic rubber-like properties but
they are not plastic.
Such material is measured by its hardness.
These materials are easily stretched and therefore they are
best suited for producing different structures.
It is very malleable and you can forge any shape through it.
Q11. What are Different Designs of
Spacer Dampers for Transmission
Lines?
There are different designs of Rayphen spacer damper.
They have different shapes and designs but their main purpose
is the same.
Their names are:
Twin Spacer Damper
It is a straight damper designed for two conductors.
Figure 3 Twin Spacer
Damper
Triple Spacer Damper
A triple spacer damper is a fan-shaped or triangular damper for
three transmission line cables.
Figure 4 Two Designs of
Triple Spacer Damper
Quadruple Spacer Damper
This Rayphen spacer damper has a square shape having 4
clamps for four overhead transmission line conductors.
Figure 5 Quadruple
Spacer Damper
Hexagon Spacer Damper
These perform the same function as twin, triple, or quadruple
spacer dampers but they have six clamps for six transmission
line conductors.
Figure 6 Hexagon
Spacer Damper
Q12. On What Factors Vibrations are
Produced in Transmission Lines?
The direction and steady speed of wind are the reasons behind
vibration production in transmission lines.
The span length of all the overhead transmission lines has a
relation with vibration frequency and wavelength.
Conductor diameter and material also contribute to the aeolian
vibration production.
The amplitude of transmission line conductors decreases as
soon as you install a spacer damper.
The same goes with ground wires.
As a result, a stable frequency is achieved.
All the wind vibration levels and fatigue removal is controlled by
this.
Ultimately, the conductor’s lifespan increases.
Q13. What Needs Attention During
Spacer Damper Installation?
Before installation, calculate the correct span length and
catenary length very precisely.
If the dampers are not placed at correct span lengths, it will
cause trouble.
Also, check that the diameter of the Rayphen spacer damper
matches with the size of the conductor to which it is going to
get attached.
Spacer alignment should be correct.
Q14. What are the Installation
Requirements of Spacer Damper?
The tools of the Rayphen spacer damper installation must be
appropriate.
Ensure to get the proper turn fastener for firm connection and
installation.
Q15. How to Install Spacer Dampers
Accurately on Transmission Lines?
Installation of a spacer damper is not a very complex task.
You just have to get the appropriate tool and weather
conditions for this purpose.
Here are the general instructions for installing Rayphen spacer
dampers in the overhead transmission line.
First, make sure you have the appropriate spacer
damper having matching size with the conductor.
Ensure to get the proper turn fastener with you.
Calculate the span length through the spacing chart
provided by the manufacturers.
Mark the place of the conductor after calculating span
length L.
Now align the spacer damper correctly.
The keepers of clamps must open downwards.
Open the nut of every clamp and place them onto
conductor cables.
Close the keeper of the clamps.
At last, tighten the bolts with the appropriate tool and
enough torque.
Check for any loose connection and you are done with the
installation process.

Q16. Is it Necessary to Regularly Check
the Installed Spacer Dampers?
No, it is not essential to regularly check the installed spacer
dampers.
As it is already mentioned before that Rayphen spacer
dampers do not need maintenance services.
Once you have installed them perfectly, there are very few
chances of them getting damaged.
It all depends on the quality and right installation.
Figure 7 Successfully Installed
Spacer Damper in Transmission Line
Q17. What Should be the Installation
Distance of Spacer Dampers?
The installation distance of spacer dampers is not specific.
There are different distances for every spacer damper.
It is generally determined by the designer.
Every Rayphen spacer damper manufacturer has a different
value of installation distance.
However, it is generally believed that conductors must be
200-300 ft apart from each other.
This is the only way you can avoid span clashing.
Spacer dampers not only provide the necessary spacing
among different conductors but also dissipate the vibration
energy.
Q18. By Which Measures Can You
Determine the Installation Position of
Space Dampers?
The only measure for determining the right position for a
spacer damper to get installed is by calculating the span
length.
Consult with the spacing chart provided with the spacer
damper and mark the conductor at an appropriate distance.
Where you have marked, place the Rayphen spacer damper
and install it.
Q19. What is a Twin Spacer Damper?
These Rayphen spacer dampers are meant for controlling the
oscillation of the conductor and vibrations produced by wind.
They also maintain a fair distance between conductors even in
case of short-circuiting.
The arm, frame, and keeper are an aluminum alloy made.
Such spacers have good quality rust-free bolts and nuts.
Q20. How to Differentiate Between
Triple and Quadruple Spacer Dampers?
The basic function and purpose of the Rayphen triple spacer
damper and quadruple spacer damper are the same.
However, they are different in their shape and appearance.
A triple spacer damper is more like a fan-shaped or triangular
spacer damper used for three cables.
On the other hand, the quadruple spacer damper has four
clamps and is a square damper.
It is meant for four-conductor cables.
Q21. What is the Method of
Replacement of Spacer Dampers on
500kV Transmission Lines?
There is no special method of replacing a spacer damper on a
500kV transmission line.
If the spacer damper needs replacement, open the bolts with
the same turn fastener used for its installation.
Open the keepers and remove the clamps from the conductor.
With installation instructions, install the new one.
Q22. For Which Types of Conductors
Using a Spacer Damper is Reliable?
Rayphen spacer dampers are used reliably for all overhead
transmission line conductors, including aluminum conductors.
They are good for ACSR, AAC, and AAAC conductors.
These are specially designed for high voltage overhead
transmission lines.
Q23. Can You Use Spacer Damper for
Insulated Wires?
No, you cannot use spacer dampers for insulated wires.
This is because normally the overhead transmission line cables
are not insulated.
You know, the spacer dampers are designed specifically for
transmission line cables and optical ground wiring.
Therefore, it is not suitable to use spacer dampers for insulated
wires and cables.
Q24. Can You Use Spacer Damper for
Extra High Voltage (EHV) Lines?
Yes, spacer dampers are used for extra-high voltage (EHV)
lines and ultra-high voltage (UHV).
For this purpose, you have to use a Rayhen spacer damper of
relatively high resonance frequency to absorb the major
vibrations produced.
Q25. What is Spacer Damper Price?
The price of a spacer damper is US$3.00-US$16.00.
The price totally depends on the manufacturers and the size of
the spacer damper.
It also is dependent on the manufacturing material.
If the material is made of good quality, the spacer damper will
be expensive than the rest of the dampers having a similar
size.
Q26. Is There Any Alternative to Spacer
Damper?
Yes, you can use vibration dampers instead of spacer
dampers.
Figure 8 Vibration
Damper
There is a condition to that.
If you want to use a vibration damper rather than a spacer
damper, you have to use a spacer separately.
It is because vibration dampers only deal with vibration
absorbance.
They are not related to providing space among the conductors.
For this reason, spacer dampers are more preferred as they
perform two functions at the same time.
Q27. Can You Get Spacer Dampers in
Various Sizes?
Yes, various sizes of spacer dampers are available to
purchase.
There are multiple sizes available according to your need.
It depends on the application and size of the conductor.
You can also customize your order at Rayphen.
For this, give your requirements and measuring.
The right product will be delivered your way.
Q28. How Can You Protect Spacer
Dampers from Damages?
Protection of Rayphen spacer dampers from rust and corrosion
is important.
They are an important part of transmission lines and are made
for the prevention of vibration harm.
Most of the manufacturers ensure good quality spacer dampers
by using good manufacturing materials.
That is why there are few chances of them getting damaged.
Over a while, they may fatigue and you need to replace them
with new spacer dampers.
Q29. Are Inter-Phase Spacer Dampers
Reliable to Use?
Yes, they are completely reliable to use Rayphen inter-phase
spacers.
They are made for various customized applications.
These spacers have adjustable lengths and are resistant to
compressive loads.
Q30. Is it Suitable for Connecting Two
Wires Using Spacer Dampers?
No, it is a bad idea to use Rayphen spacer dampers for
connecting two wires.
This overhead transmission line accessory is not a cable
connector.
It is designed for absorbing wind vibrations along with providing
a fair distance among transmission line conductors.
Q31. Can You Reinstall a Spacer
Damper?
No, it is not good to reinstall used spacer dampers.
When they are installed once on a transmission line or ground
wires, they are just like fixed to the conductors.
Removing them and using them again is not suitable.
If you feel like there is a need for a Rayphen spacer damper,
always use a new piece.
The old and weary spacer dampers cannot work to their best.
Q32. How Can You Get Customized
Spacer Dampers?
Getting a customized spacer damper is not a difficult task.
You can order the customized dampers at Rayphen.
Place your orders by telling your requirements.
