Suspension Clamp for ABC, ADSS and Overhead Line

Suspension Clamp Buying Guide

When working on electrical and telecommunication installations, there are two key components that you cannot avoid.

If you want to learn more, please visit our website china adss corona coil.

These are cables and poles.

In most cases, the cables are usually hanged to the poles or even towers.

They are responsible for transmitting electricity or communication signals from one point to another.

So, what makes the cables or conductors hang so easily yet the whole process looks delicate and complex?

It is because of one tool: Suspension clamp.

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.

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

-AGS suspension clamp

-Suspension clamp for ADSS cable

-Double suspension clamp

– Preformed suspension clamps

-Cable suspension clamp u-type

So, which type of suspension clamp do you think will meet your specific needs?
