What are overhead power line fittings? Simply defined, power line fittings are accessories installed on transmission lines for the purpose of creating connections and attachments between different components.
These fittings also protect certain components of the transmission line from physical and mechanical damage.
Each power line fitting is intended to play a specific role in the power line. For example, fittings for conductors are attached to cables to suspend or terminate conductors. The same fitting protects the conductor from loss of current.
The same applies to power line fittings for insulators. They are also connected to the insulating components of the transmission line.
Before you make any decisions, it is important to determine the role played by each pole wire fitting.

When purchasing transmission line hardware fittings, it is vital to know each of their properties. This information will be used to determine the performance of that accessory.
The following is a breakdown of the main characteristics of powerline hardware that you should be aware of.
Mechanical properties define the general working mechanism of a powerline fitting and how it interacts with the other components of the pole hardware.
Some of the mechanical properties you should be aware of include, but are not limited to
- Turning angles: As most transmission line hardware is subject to different mechanical forces, it is vital to understand the maximum and minimum angles they can turn.
- External forces: This is about the maximum pressure that an overhead transmission line conductor can withstand without breaking, snapping or even being damaged.
PG Clamp
Material properties are used to define how strong or weak the transmission line attachments are. This is in line with the fact that different they are made of different types of material.
One of the key material properties is the hardness of the material. It will determine whether the power cable accessory is strong or not.
The material of the power cord accessory should be strong enough to resist physical forces.
Another key aspect of the material's properties is its resistance to corrosion and abrasion.
Overhead power line fittings are exposed to the natural environment and as such they are bound to be subject to corrosion and wear and tear.
Fittings should be coated with corrosion and abrasion resistant agents so that they are adequately protected.
Pigtail Hook Bolts
As these power line accessories will be used to transmit electrical energy, they need to have ideal electrical properties.
One of the key electrical characteristics is the ability of the overhead power line installation to withstand fault currents. This is the current generated when the power line is short-circuited.
Transmission accessories should also be able to prevent hysteresis losses. This is the current generated due to the interaction between the current and the magnetic field.
In general, good electrical performance means that the power line accessory does not cause any interference with the normal flow of current.
Design properties define the general appearance of overhead power line fittings. It highlights issues such as the shape and size of the accessory.
The design attributes will determine how the fittings will be installed and how the fittings will be connected to other components on the pole.
Another design attribute you need to look at is dimensionality. Check all measurements of the accessory, such as length, diameter, thickness etc.
You should also confirm the shape and alignment angle of the power cable fittings. They should fit your requirements.
When purchasing drive hardware accessories, ensure that the design dimensions are accurate. Well-designed fittings will operate effectively as intended.
You'll also have an easy time installing overhead powerline accessories designed for precision.
