What is a Suspension Clamp?
A suspension clamp is a fitting that is designed for suspending or hanging cables or conductors to the pole. In other cases, the clamp can suspend cables to the tower.
Since the cable is directly connected to the conductor, its specifications need to match with that of the cable so as to create a perfect connection.
A suspension clamp hangs the cables at different points and angles depending on the requirements of the project.
What are the Uses and Applications of a Suspension Clamp?
While the primary use of suspension clamp is to suspend hang or suspend a conductor, there are other roles that it plays.
A suspension clamp protects the conductor during the installation of the transmission line onto the pole.
The clamp also provides a mechanical connection by ensuring that there the right longitudinal grip on the transmission line.
Suspension clamps also control the movement of cables against external forces such as wind and storm.
From the above listed uses, suspension clamp is applicable in different projects that have conductors hanging from poles.
The most common applications are electrical pole overhead lines and transmission lines.
Parts and Components of Suspension Clamp
From a distance, you can easily assume that a suspension clamp is a single homogeneous accessory. The truth of the matter is a suspension clamp comprises of different parts which include:
1. The Body
The body is the supporting frame of a suspension clamp for the conductor. It supports the whole fitting.
The body is made of aluminium alloy which apart from being strong is also resistant to scratches and corrosion.
2. Keeper
The keeper of a suspension clamp plays the role of connecting the conductor of a transmission line to the body of the suspension clamp.
3. Straps
These are string-like structures that are responsible for transferring the load from the axis of oscillation straight to the insulator string.
These straps are capable of playing this role because they are made of coated zinc material.
4. Washers
The washers of a suspension clamp are usually put into use when the clamping surface is not rested perpendicularly.
They are made of steel to provide the necessary support while at the same time resist corrosion.
5. Bolts and Nuts
Since a suspension clamp is also a mechanical device, there will always be a need to secure all the connections.
This is where the role of bolts and nuts come into play. Any connection that is made to a suspension clamp is completed using bolts and nuts.
Bolts and nuts are also made of steel for strength and resist corrosion.
6. Threaded Inserts
When you see threads or bushings on a device, the first thing that should come into your mind is the device needs to be fastened.
The threaded inserts of a suspension clamp are simply fastening elements. They are inserted to elements that have threaded holes to complete the connection.
Threaded inserts are also made of stainless steel.

You do not need to worry if you do not know anything about tension clamps. Here, in this guide, we will answer all the questions you have in mind regarding tension clamp. The guide includes its definition, functions, installation, features, and much more.
Let&#;s move to the FAQ guide very straight now!
A tension clamp is overhead fitting hardware that terminates the conductors.
It gives electrical and mechanical connections to insulators wrapping the conductors.
Figure 1 Tension Clamp
Such clamps provide linear connections as well as twisted connections to the conductors.
They are suitable for different types of conductors, including ACSR, ACAR, AAAC, and AAC conductors.
It can also be used to accompany copper conductors to some extent.
Tension clamps have different types based on various properties.
Such clamps come in different shapes, sizes and forms.
You can also get customized tension clamps by Rayphen.
Well, as you know, what exactly is a tension clamp.
Strain tension clamp has wide applications in the telecommunications and electrical industries.
Let us tell you how they are being employed in big industries.
It has the following uses.
Without any doubt, the strain tension clamp provides a basic connection to conductors at terminals and along the overhead line.
They offer reliable connections to cables whether having longitudinal tension or the maximum strain for working.
These Rayphen tension clamps give connection by secure clamping action through their perfect designs.
Strain tension clamp not only provides connections to the conductors but also protects them.
Such clamps offer protection during installation and after installation too.
With maximum holding grip, strain tension clamp restricts the movement of the conductor.
It keeps the conductor fixed at one point and does not loosen them even for a bit.
Due to strong winds and rainstorms, electrical line fittings displace their positions.
This directly affects the working efficiency of the entire aerial line.
To control this situation, a strain tension clamp comes to the rescue.
The limited conductor movement by the Rayphen strain tension clamp ensures a smooth and steady flow of electric current.
There are so many types of tension clamps.
It means the tension clamp has multiple distinguishing key features. These are:
The tension clamp is very easy to install.
You only need a few simple tools for its installation.
The designs of all types of tension clamps are unique and highly interactive with the conductors.
The versatility in designs makes the tension clamp highly reliable to use with different conductors.
You can have different diameters according to the diameter of the cables.
The tension clamp is waterproof.
It resists water and humidity in the environment.
That is how it gives a corrosion-free finish with the conductors.
The Rayphen tension clamp is strong mechanically as well as electrically.
Such clamps have a stronger grip on the conductor.
The tension clamp at Rayphen is made from genuine raw materials.
Hot dip galvanized technology also does wonders with the finishing of the final product.
It makes the tension clamp corrosion-proof and gives it a smooth shiny look.
Tension clamp has so many varieties.
There is a tension clamp for hydraulic applications but we will stick to the tension clamp types related to electrical connections.
The various types of tension clamp on the basis of designs and some other characteristics are:
The Rayphen compression tension clamp is highly suitable where you need to put a lot of compression force on the conductors.
Figure 2 Compression Tension Clamp
It performs its function brilliantly by keeping the conductor fixed to a point.
Compression tension clamp has different working load values and is operated for different values of amperage.
The design of this type of tension clamp enables it to interact perfectly with the conductor surface holding maximum tension.
It changes the tension into clamping compressive load through its wedge.
The wedge-shaped tension clamp is widely used for its excellent working efficiency.
Rayphen wedge tension clamp emphasizes extraordinary clamping to the cables, both insulated and non-insulated.
Figure 3 Wedge Tension Clamp
Such clamps tend to provide maximum protection and make sure the anchoring is done accurately with the conductors.
The body is aluminum hot dip galvanized while the rod is made of stainless steel.
You can see wedge tension clamps on distribution lines and overhead connections.
They are also named quadrant strain tension clamps.
As the name indicates, bolted clamps are accompanied by 2-4 bolts that require tightening.
The tightening torque value of the Rayphen bolted tension clamp is mentioned in the fitting.
It serves the purpose of providing adequate tension, holding the conductors, and restricting their movement in a strong wind environment.
Figure 4 Bolted Strain Tension Clamp
The bolted strain tension clamp gives a smooth corrosion-free finish to the conductor connection.
That is why they are an important part of large-scale industrial projects.
A cone tension clamp is nothing different from a wedge tension clamp in function and mechanism.
It only differs in the fact that it has a cone instead of a wedge part.
In the Rayphen cone tension clamp, the clamping is performed by the cone.
Whereas, in the wedge tension clamp, the wedge performs the clamping mechanism.
The overall features and characteristics of a cone tension clamp are similar to other types of tension clamps.

Dead end tension clamps are quite famous and you have frequently seen them operating on aerial lines, distribution lines, and utility poles.
Such a tension clamp provides a dead ending to the terminals of the conduction making the termination easy and reliable.
Figure 5 Dead End Tension Clamp
They are easy to install and have weather-resistant properties.
The Rayphen dead end tension clamp is compact in structure and its assembly parts are very efficient.
The Rayphen tension clamps designated to work in warmer environments or that can bear high-temperature values are known as high-temperature tension clamps.
High temperature tolerating tension clamps can be of different types, including dead end, cone, bolted, compression tension clamp, etc.
The design of a high-temperature bearing tension clamp is not different from the rest of the tension clamp types.
The basic functioning and construction of high-temperature tension clamps are the same as other clamps.
Tension clamps have two types depending upon the function. These two types are:
This particular tension clamp type tolerates the stress or tension of the cables and conductors.
The grip strength of tensioning clamp is quite high.
The value of grip strength equals 90% of the conductor&#;s resistance.
Tensile clamp at a time displays two functions.
It absorbs the pull from the conductor and also performs as a conductor itself.
You need to install such Rayphen tension clamp with complete care when they are used as conductors.
The tension clamp is made with high-quality raw material and under the hot-dip galvanized technology to make the clamps corrosion-free.
Hot-dip galvanization also makes the surface of tension clamps smooth and prevents the bumping of metals used for their production.
Here, let us tell you the materials used for making different types of tension clamps.
The commonly used manufacturing material for tension clamps is aluminum and its alloys.
Aluminum provides enough ductility and hardness to the final product that makes the tension clamp easy to fit and use.
It has a low melting point means you can make different shapes out of it.
Therefore, most of the time the aluminum alloys are employed in the manufacturing process.
They have small quantities of other heavy metals such as iron that provide elasticity and hardness to the tension clamp.
Hence, aluminum and its alloys are referable for making different types of tension clamps.
You can ask for any aluminum tension clamp type quite easily at Rayphen.
Rayphen aluminum alloy tension clamp is perfect for conductors such as ACSR, AAAC, and AAC.
Malleable or molding iron is the second favorite when comes to tension clamp manufacturing.
It has an excellent casting property and you can convert it into different designs.
The assembly parts of the tension clamp made from malleable iron perform equally well as the aluminum parts.
Cast iron tension clamps come in different sizes.
Some of the tension clamps also contain fiberglass parts.
They are thermostable and provide shear resistance against weather conditions.
Fiberglass tension clamp is applicable to light in weight conductors.
They are also protective against the ultraviolet radiation coming from the Sun.
The strong impact of mild steel is very high and it is a highly malleable material.
A tension clamp of mild steel or stainless steel is also available.

It means you can get different ADSS tension clamp based on different voltages and spans.
Yes, fortunately, you can purchase a waterproof tension clamp at affordable prices at Rayphen.
It is the demand of any electrical setup to be fully waterproof.
This is because, in an environment that is exposed to water, humidity or water of any sort could be dangerous for the electrical connections.
It can cause damage at a large scale and is risky to human lives as well as livestock.
A simple small spark can lead to fire and explosion.
To avoid all this, you need an electrical fitting that is water-repelling.
So is the case with tension clamp.
Using a waterproof tension clamp of good quality is not only economical but also safe to use.
It stops the sparking and also stops the flow of eddy current due to losing connections.
The tension clamp is compatible with different conductors and cables.

Overhead lines include aerial cables, ABC insulated cables, distribution lines, telecommunication lines, and power transmission stations.
For overhead connections, a corrosion-proof and weather-resistant tension clamp is ideal.
Such clamps give maximum mechanical grip to the conductors and make them fixed to their designated positions.
What do you think of tension clamp and preformed tension clamp?
You are thinking they both are the same?
Well, not exactly.
They both are tension clamps but their design and construction are quite distinguishing from each other.
A preformed dead end grip is also another name of a preformed tension clamp.
It is steel made whereas tension clamp is aluminum made mostly.
A preformed tension clamp is a spring-like wire twisted to form a loop kind of structure.
It gets wrapped up in the wires and cables and holds them.
Figure 10 Preformed Tension Clamp
Yes, you can purchase a fireproof tension clamp from different sources.
Purchasing a fireproof tension clamp is always good.
It prevents the whole electrical network to catch fire in unfortunate circumstances.
These fireproof tension clamps are also waterproof and weather resistant.
The fireproof property of tension clamp is for types of a tension clamp.
You can ask for any tension clamp such as wedge tension clamps that work best with aluminum conductors.
The interactive forces between the tension clamp and the surface of conductors are determined by the design of the tension clamp.
As you know, there are many tension clamp types.
Each has a specific design from the other.
It means each one of them has a different physical interaction with the conductor surface.
The more efficient the design of the tension clamp, the stronger is the physical interaction with the conductors and cable surfaces.
Compression tension clamp, strain tension clamp, and wedge tension clamp are among the best interacting tension clamps with any conductor.
They are available in various sizes and forms based on applications.

The prices of the tension clamp vary with the raw materials used.
It also depends on the type of tension clamp and the manufacturers too.
If you are dealing with electrical clamps and conductors, breaking load is a must known thing to you.
If you do not know, we will tell you how to determine the breaking load for your tension clamp.
It is the measure of the maximum pressure that you should apply so that the tension clamp cannot break.
If you apply any pressure beyond its breaking load value, the tension clamp will break.
Resultantly, it will damage the conductor too.
The tension clamps come with designated breaking load values from reliable manufacturers like Rayphen.
In case of a power increase, the temperature of the conductor also increases.
High temperature tolerating cables or conductors are employed in such places and so is the tension clamp.
These conductors can bear a temperature as high as 235°C.
The tension clamp attached to the conductor at high temperature must bear this heating without getting affected.
It means you should use a tension clamp of greater surface area and mass.
So that there is a decrease in thermal loss level and the current flows continuously.
