Pulished on Feb. 04, 2023

Socket Clevis, also known as socket tongue, is a very integral part of pole wire technology.

It is commonly used in overhead lines, transmission lines and power lines.

It is the main component in the pole line hardware that usually connects the sleeve insulator to the tension wire clamp.

Why do I need Socket Clevis?

The Socket Clevis is used for certain applications as an integral part of the pole hardware.

It connects a sleeve insulator to a tension clamp or bracket.

It is used as an accessory to connect a string of insulators. Examples include "ball and socket, U-clip and tongue and groove connections, yoke plates for multiple strings of insulators".

It can also be used as an electrical link on power lines.

In overhead lines, it is used as an integral part of the electrical power supply to trains, trolleybuses and trams.

In transmission lines, it is part of a system designed to help conduct alternating current in radio frequencies.

The main components of Socket Clevis

Socket Clevis is a component of various parts and assemblies.

Although they vary in design and shape, here are some of the most common parts.

1. Anchor Release Clip

It is a piece of metal, usually U-shaped and held in place with a U-clamp pin and bolt.

In addition, it can be secured using an articulated metal ring with a quick release locking pin mechanism.

It acts as the main link in different link systems because they provide quick connection and disconnection.

2. U-pin

It is an integral part of the U-clamp fastener, which has three main components, including the U-clamp pin, U-clamp and shank foot.

The pin is available unthreaded or threaded.

The unthreaded pin has a dome-shaped head on one end and a cross hole on the other.

To hold the U-clamp pin in place, a cotter pin or cotter pin is used.

The other end has a threaded pin that forms a head on one side and only has threads on the other side.

The nut comes in handy when the pin must be in place.

3. U-shaped clip bolt

It can be used to replace the U-clamp pin, even though it does not bear the stresses handled by the U-clamp pin.

They are used to carry and hold the tension load.

4. Cotter pin

It is also known as a cotter pin, depending on the country/region where it is used.

Remember, it is a piece of metal that is used as a fastener and its end is bent during installation.

It is used to hold two pieces of metal together. 5.

5. Bolt

It is a fastener that uses external threads and has similarities to a screw.

It is usually used in conjunction with a nut.

One end is the head of the bolt and the other end is externally threaded.

6. Nut

It is a fastener with a threaded hole.

It is used with bolts to fasten or join different parts together.

This partnership holds threads together by friction.

In addition to this, it depends on the tension and compression of the parts that are joined together.

Socket Clevis Technical Specifications

Before purchasing Socket Clevis, please make sure to note the following key technical specifications.

1. Type of material

The types of materials used to manufacture Socket Clevis are steel and iron.

These materials are preferred because they are strong enough and can withstand weight and pressure.

2. Surface Finish

Socket Clevis is hot dipped galvanized to make it corrosion resistant.

Hot dip galvanizing involves dipping an iron or steel U-clip into zinc to plate it and give it a final smooth touch.

The steel is immersed in molten zinc at a temperature of 449 degrees Celsius.

3. Dimensions

The dimensions on Socket Clevis vary depending on the size of the device.

In addition, the larger the size of the Socket Clevis, the larger the size.

The width and length are measured in millimeters, while the weight is measured in kilograms.

4. Design

The design of Socket Clevis depends on the company that manufactures it.

Usually, the customer has a say in the type of design he needs and in the execution of the task.

The design of Socket Clevis must match the function it is intended to perform.

5. Load Rating

The load rating on the Socket Clevis depends on the amount of power it will handle.

The customer must specify the function the u-clamp will perform before purchasing the u-clamp.

The manufacturer will then advise on the Socket Clevis with the most appropriate load rating.

6. Weight

The weight of Socket Clevis depends on the size of the device, the material used to manufacture the device.

Other materials are heavier than others, resulting in a wide variation in weight.

Dimensions such as width, length, etc. do vary and so does the weight.

Socket Clevis Manufacturing Process

YIPENG manufactures Socket Clevis from cast iron.

The manufacturing process starts with heating, forming, and annealing, followed by hot dip galvanizing.

Materials: The main raw materials required are iron and Socket Clevis molds.

This process requires some very expensive machinery.

This is why it is left to major industries such as King Young to manufacture.

ㆍNote: The process of making U-clips involves handling iron at very high temperatures.

This is a dangerous process and you must be very careful when handling the iron.

You should also wear protective clothing and boots to protect you from any accidents that may occur.

ㆍMeasuring: This is the process of obtaining the correct size material to be used for fabrication.

In the case of custom Socket Clevis, this is done according to the customer's specifications.

The material is cut into the required pieces before the rest of the process is carried out.

ㆍHeating process: Cast iron is heated at very high temperatures to melt it.

Cast iron is the most preferred material because it melts at a lower temperature compared to other materials.

It changes from a solid to a liquid state.

The iron is very hot and extra care should be taken during this process.

In addition to its low melting point, cast iron has good fluidity, excellent machinability, wear resistance and resistance to deformation.

These properties make it the most preferred material when making Socket Clevis.

ㆍMolding: The molten iron is then poured into a Socket Clevis mold.

The mold is shaped so that it has a hole similar to that of the sleeve tongue.

The liquid iron takes the shape of the mold, which is the shape of the Socket Clevis.

ㆍAnnealing: The third step is annealing, which is a form of heat treatment that changes the microstructure of the iron.

This is the process that brings Socket Clevis to its strength, hardness and ductility.

ㆍCooling: The fourth step is to allow the mold iron to cool.

The cooling process is slow to allow the die to retain its shape without breaking.

Hot dip galvanizing is the final process that the cooled iron goes through.

This involves the use of zinc coated Socket Clevis to protect it from corrosion.

Socket Clevis is immersed in molten zinc at a temperature of 449 degrees Celsius.

At this point, the Socket Clevis is ready and inspected to ensure it is ready for use.

How do I install the Socket Clevis?

Installation of the Socket Clevis is a process that requires you to secure the rod in place before attempting to install it.

ㆍMake sure all materials are also in place and that you can use a ladder to lift you to the desired height.

ㆍThe insulator string should be assembled on the ground before climbing the pole. It is easier to assemble the strings on the ground than at the top of the pole.

ㆍInsulators and accessories are also mounted on the ground and at a higher height.

ㆍGround assembly is preferred for more efficient installation, especially when construction conditions are in place.

ㆍWhen construction is limited, assembly is done at high altitudes.

ㆍDuring the installation of insulators and accessories at high altitudes, workers lift tools, ropes and steel straps up a ladder.

ㆍThe mounting positions of the cross arms are marked and pulled with the help of ropes.

ㆍThe cross arms are put in place and then other hardware, such as insulators and insulator strings, are installed.

ㆍThe Socket Clevis is a very important component of the pole line hardware and is installed by a professional.

ㆍThe task it is expected to perform requires an experienced person to install it, as mistakes are not acceptable.

ㆍIt is also very dangerous to try to install it without the help of others, which means it cannot be done alone.

Different companies offer customized products according to the customer's specifications.

Socket Clevis is available in different sizes and designs, as long as it fits and functions well.

As a customer, you are advised to be careful when purchasing Socket Clevis because they have different load factors.
