Do you have plans of buying a clamp suspension?

Read on as we guide you on what you need to know about this product.

What is a Suspension Clamp?

To start us off is the suspension clamp definition.

Also known as a suspension fitting, this is an accessory that is specially designed to hang the cables or even the conductors to the pole or even tower.

The clamp is specially constructed so that it is compatible with a  wide range of cables and conductors.

Suspension clamp hangs the ABC cables through different angles hence giving them proper support and protection.

To help you understand better, here is a picture of a typical suspension clamp.

As you can see, there is nothing complex about it.

You only need to buy and use it.

Uses of a Suspension Clamp

We have already mentioned the primary function of suspension clamps.

But, it sounds so general, doesn’t it?

Probably, you are looking for the specific functions of suspension clamps.

Here are some specific functions of suspension clamps:

-Suspension clamps protect the conductor right at the installation load.

-The clamps provide a safe and viable mechanical connection regardless of the condition. They achieve this by providing an adequate longitudinal grip control.

This means that the conductor can be released from the clamp only through defined slip loads hence preventing physical damage.

-Suspension clamps control the movement of the conductor. This provides protection against the vibrations that have been induced by strong winds.

Parts of a Suspension Clamp

Just knowing the physical appearance of a suspension clamp is not enough.

It is important that you go further and familiarize yourself with its components.

Here are the parts and components of a typical suspension clamp:

1.The Body

This is the part of the suspension clamp that is responsible for supporting the conductor.

The body is made of an aluminum alloy mainly due to the strength of the material.

It is hard and resistant to stress corrosion.

2.Keeper

This is the part of the clamp that connects the conductor directly to the body.

3.Straps

These are parts of the suspension clamp that transfer load right from the axis of oscillation to the insulator string.

What type of material is used on the straps?

The straps mainly consist of a thick zinc coating.

4.Washers

The importance of this part comes into play when the clamping surface is not perpendicular.

Washers are made of stainless steel and are resistant to corrosion.

5.Bolts and Nuts

Obviously, you know the function of bolts and nuts in any mechanical device.

They are mainly used to complete connections.

Also, the bolts and nuts are made of stainless steel which is known for its strength

6.Threaded Inserts

Sometimes they are known as the threaded bushing.

But, what role do they play in a suspension clamp?

They are basically fastener elements.

This simply means that they are inserted into an object to add a threaded hole.

Like other major parts of the suspension clamp, they are also made of stainless steel.

Design Requirements of Suspension Clamp

What does the design requirement of a suspension clamp entail?

It ensures that there is proper coordination between the physical and mechanical aspects of the suspension clamp.

Also, design requirements ensure that all parts are in their correct position.

This will facilitate the smooth operation of the suspension fitting.

-Anchor clamp

First, you should be able to move the anchor clamp which is next to the conductor freely.

To achieve this, ensure that the trunnion of the clamp is part and parcel of the body.

-Conductor supporting groove

When buying suspension clamp, ensure that the conductor supporting groove has the right measurements.

Check the measurements as indicated by the suspension clamp manufacturer.

The body and the keeper should not have sharp edges or any form of irregularities.

-The design of the straps

When buying a suspension clamp for overhead, try to check the design of the strap.

Ensure that they are round and their sizes match directly with that of the trunnion.

-Designs for bolts and nuts

Although they may look small, they also have strict design requirements,

When buying a suspension clamp or even aerial cable clamp, check for the positioning of the bolts and nuts.

Ensure that they are well attached to the clamp.

They should be well attached to prevent them from dropping when the clamp is in operation.

When it comes to the design ensure that the bot can protrude outside through the thread.

Mechanical Requirements for Suspension Clamp

When you hear the word  ‘mechanical’, what comes into your mind?

To most of us, we think of the machines and how they operate.

Well, in this context, the mechanical requirement is all about the operation of a suspension clamp.

So, what are these requirements?

First, a suspension clamp should be able to withstand the deformation load without showing any signs of getting damaged.

This is a requirement that should be fulfilled even if the conductor turns at 30 degrees.

Also, the clamp should be able to withstand the bolts and nuts regardless of how tight they may be.

Types of Suspension Clamps

Do you know that there are different variants of a suspension clamp?

In other words, there is no universal suspension clamp.

Instead, you can buy suspension clamps that have a set of particular specifications that will fully meet your needs.

In most cases, each variant is designed for a specific cable.

Here are the most common types of suspension clamps:

-Suspension clamp for ABC cable

-Suspension clamp for opgw

Cable Suspension Clamp

Suspension Clamp Manufacturer

TTF Power manufactures and supplies suspension clamps for overhead power transmission and distribution systems. Suspension clamp for ABC cable protects the conductors and other devices from aerial vibrations and swinging caused by strong winds and storms. The clamps are made from galvanized steel and aluminum alloy, which helps them to resist corrosion caused by the different weather conditions in the environment. The resistance offered helps to increase the durability of the suspension clamps for overhead lines which in turn helps to reduce the repair and maintenance life costs.

They are used together with other devices such as bolts, nuts and washers to assist in securing a connection on the overhead lines. This help to limit loose connections that may eventually lead to electrocution. These devices should be made from similar material as the conductors as they are installed near the conductors to help reduce abrasion and friction of the different devices.

The production of the cable suspension clamp may vary in functionality and operability due to the different designs, mechanical and technical abilities of each make. They are therefore used for different applications and functions in the installations of the overhead transmission lines.

Components of suspension clamp

Suspension clamp is not a single entity as it has some major components that make up the connection to the conductors. They are as discussed below.

• The body– this is the frame supporting the ADSS suspension clamp for the conductor and it is made of aluminum alloy which is strong and also resistant to corrosion. This helps to maintain the durability of the OPGW suspension clamp.
• The keeper – the role of this part is to connect the conductor of the transmission line to the body of the helical suspension clamp.
• The strap – this are string-like constructions that are responsible for transferring the load from the axis of the swaying straight to the insulator string. The straps are perfect for the role as they are made of coated zinc material that helps them to achieve their purpose.
• Washers – these are usually put into use when the clamping of the surface is not rested vertically. This helps to provide support to the aluminum suspension clamp and the conductors. They are made of steel which helps them to resist corrosion and rust.
• Bolts and nuts – the bolts and nuts are used when the fiber optic suspension clamps are used mechanically in order to secure the connections. They are also made of steel to provide strength and resistance to corrosion.
• Threaded inserts – these are fastening elements for suspension clamps which are injected into components that have threaded holes to complete the connection. The threaded inserts are also made of stainless steel to resist corrosion and rust.

Types of suspension clamps

Suspension clamps for overhead lines are made in different designs and models as they have different roles on the transmission lines. They are each made for a particular function which means they cannot be interchanged. These types of cable suspension clamps should be selected for specific functions for the transmission lines.

1. Bolts and nuts — the designs of the bolts and nut should also be considered so that they can perfectly fit into the ABC suspension clamps during construction. They should also be from a similar material as the conductors.
2. Design of straps — the straps of the suspension clamp should be round-shaped and sizes should match with the sizes of the trunnion.
3. Anchor clamp — this is the one next to the conductor and should be able to move freely to allow the conductor to move. The design is attained if the trunnion of the clamp is part of the body.
4. Conductor supporting groove — the conductor supporting groove should have the right measurements for the application. The keeper of the fiber optic suspension clamp should not have any sharp edges that can produce any anomalies.

Uses of the suspension clamps on the transmission lines

The suspension clamp main use is to suspend the conductors hanging from the transmission lines. They ensure a safer connection of the above lines. They however have other important uses which are as follows.

• The cable suspension clamps help to hang and suspend the conductors.
