Company Profile: As early as in the 14th century, the company active under the name of “Mosdorfer” since was mentioned as a smith’s shop on the Weizbach. In the middle of the 18th century, Mosdorfer almost obtained a monopoly for supplying the imperial army with sabres. When the production of blades ceased to be a field of business promising a secure future, Mosdorfer applied for the license to produce sickles. In the 19th century, yearly production of sickles reached its highest level with about 500,000 pieces. Even then Mosdorfer was a company that was active worldwide and exported its products to such countries as Turkey, Russia, Brazil or the US.

Overhead line fitting comprise of different accessories installed on the transmission lines in order to initiate connections and attachments between different components.

They are used to mechanically provide the network for electrical connections and insuring insulators and conductors in their place. Fittings are designed for different purposes such as terminations, suspension or joining the conductors.
Some of the fittings are also used to protect some of the components against mechanical and electrical damages.

Types of Overhead Line Fitting

Cross Arm Brace

These connects the electrical cross arm by bolts and nuts.

Electrical Cross Arm

It is equipment used for holding electric equipment such as power lines.

Electric Powertek contains other products and information you need, so please check it out.

Alley Arm

It is a sidearm brace that is fashioned to brace a cross arm that is rough. It has a straight edge and a slightly bent side.

Ball Clevis

This is designed to connect the socket insulator by its ball.

Pole Top Bracket

Bracket is used for mounting line post insulators onto the desired positions.

Pole Top Pin

It uses it bolts to support the insulator on top of the pole.

Socket Clevis

It completes the connection between socket clamp and socket type insulator.

Stay Rod

This provides a point of attachment for the guy wire. It insures that the wire is supported firmly to the ground.

Suspension Clamp

Suspension clamp is used to suspend cables or conductors to the pole.

Yoke Plate

Yoke plate is used to couple the electrical clevis and the insulators or the socket tongue.

Guy Clamp

This has grooves through which the cable and conductor pass.

Guy Thimble

This holds the stay wire into its position.

Properties of the Overhead Line Fitting

Mechanical properties determine the general working mechanism of the component and how it interacts with other components in an overhead line. This may include the angle of turn of the components since most transmission line hardware is prone to different mechanical forces. It also includes exertion force which determines the maximum pressure which the overhead conductors can withstand without breaking, bending or getting damaged.

Material properties of the component are important to determine how weak or strong the components are since they are made of different materials. One of the properties includes the hardness of the material which make them strong and resistance to corrosion.

Electrical property of the material include the ability of a component to withstand electric fault current, it should also be able to prevent the current that is created as a result of the interaction between electric current and a magnetic field. They should not cause any interference with the normal flow of the current.

Design of the material is also important as it determines he general outlook of the transmission line. They include aspects such as size, shape and dimensions of the component. These factors contribute to the installation of the components.

Conclusion

In summary, the overhead line fittings are components used in creating connections between the overhead lines and different components. They should meet certain criteria to enable effective use by the end user. This means they should have a hard material that is galvanized or made from stainless steel to be able to resist corrosion and improve the life expectancy of the overhead line structures.

They should also be in the best sizes, shapes and angles to help in easy installation. They should be able to conduct electricity and cause no interference with the flow of current to enhance efficiency. These fittings are mostly applicable in telecommunication lines, fabrication, mining and medical departments. They are also used in supporting different structures that ensure delivery of power to the utility areas such as homes, schools, hospitals and streets.
