An overhead power line is an infrastructure that is used for the transmission and distribution of electricity. The distribution can be over either a short distance or a long distance depending on the scope of the project.
Overhead power lines are capable of transmitting different amounts of voltages. Although they are usually used for high voltage power transmission, you can also use them for the low voltage.
Most overhead power lines are characterized by cables that are suspended across poles and towers.
To ensure that everything on the pole is in its perfect position and functions well, you will need overhead power line fittings.
What are the functions of the overhead power line fitting and which one should you buy for your project?
We have the answers to these and many other questions that you have regarding the pole line fitting. All that you have to do is read on this guide.
In this guide, I am going to guide you on how to buy the best overhead power line fitting
What is an overhead power line fitting? Simply defined, power line fittings are accessories that are installed on the transmission lines for the purpose of creating connections and attachments between different components.
The fittings also protect some components of the power transmission line against physical and mechanical damage.
Each electrical power line fitting is designed to play a specific role in the power line. For example, the fittings for the conductors are connected to the cable to suspend or terminate the conductor. The same fittings can also protect the conductor against the loss of electric current.
The same applies to the power line fittings for the insulators. They are also connected to the insulating components of the transmission line.
It is important to identify the role that is played by each pole line fitting before you make any decision.
Here is different power line hardware each one is designed to perform ts specific role.
The fitting include:
Alley Arm: It is a sidearm brace that is designed to brace a crossarm that is uneven. The arm features a straight edge and the other side is slightly bent.
Ball clevis: Also named clevis eye, it is designed to connect the socket insulator by its ball.
Cross arm brace: The same function as alley arm brace – just different construction.
Electrical Cross Arm: It is composite equipment utilized in the pole line technology for holding electric equipment such as power lines.
Pole top bracket: This fitting is used for mounting line post insulators onto the desired positions.
Pole top pin: It supports the insulator on top of the pole with the help of bolts.
Socket clevis: Also known as sock tongue, it is designed to complete the connection between socket clamp and socket type insulator.
Stay Rod: This accessory provides a point of attachment for the guy wire. It ensures that the wire is supported to the ground firmly.
Suspension clamp: The clamp is used for suspending cable or conductor to the pole.
Yoke plate: This hardware is used for coupling the electrical clevis and the insulators or the socket tongue.
Guy Thimble: The guy thimble plays the role of holding the stay wire into position
Guy Clamp: The clamp has grooves through which cable and conductor pass.
When buying transmission line hardware fittings, it is vital to know each of their properties. This information will come in determining the performance of that fitting.
Here is a breakdown of the key properties of power line fittings that you should know:
Mechanical properties define the general working mechanism of a power line fitting and how it interacts with other components of the pole line hardware.
Some of the mechanical properties that you should know include but not limited to;
-The angle of turn: Since most transmission line hardware is subjected to different mechanical forces, it is vital to know the maximum and minimum angles through which they can turn.
-Exertion force: This is all about the maximum pressure which the overhead transmission line conductor can withstand without breaking, snapping, or even getting damaged.
The material properties are used for defining how strong or weak is the transmission line accessory. This is in line with the fact that different they are made of different types of materials.
One of the key material properties is the hardness of the material. It will determine whether the power line fitting is strong or not.
The material for your power line fitting should be strong enough to resist physical forces.
Another key aspect that comes with material properties is resistance to corrosion and abrasion.
Overhead Power Line Accessories are exposed to elements of nature hence they are bound to undergo corrosion and abrasion.
The fitting should be coated with anti-corrosive and anti-abrasive agents so that it can have full protection.
Since these power line accessories will be used for the transmission of electric energy, they need to have desirable electrical properties.
One of the key electrical properties is the ability of an overhead power line fitting to withstand the fault current. This is the current that is produced when there is a short circuit on the power line.
The transmission accessory should also be capable of preventing hysteresis loss. This is the current that is created as a result of the interaction between electric current and magnetic field.
In general, an excellent electrical property is when the power line fitting does not cause any interference with the normal flow of electric current.
Design property defines the general outlook of the overhead power line fitting. It highlights issues such as the shape and dimensions of the accessory.
The design property will determine how the fitting will be installed and how it will connect with other components on the pole.
Another design property that you need to look at is the dimension. Check all the measurements of the accessory such as length, diameter, thickness, among others.
You should also confirm the shape and angle of alignment of the power line fitting. They should match your requirements.
While buying transmission hardware fittings, ensure that the dimensions of the design are accurate. A well-designed fitting will function effectively as expected.
You will also have an easy time when installing an overhead power line accessory that has been designed for precision.
Among the many critical decisions that you will make when buying power transmission accessories, one of them is choosing the manufacturer or supplier of the fittings
Even though it may seem to be a non-issue, it is something that can affect the quality of the overhead power line fitting that you buy.
Buying from the best transmission line hardware manufacturer will guarantee you quality overhead fitting. The reverse is true if you choose to buy from a not so reputable manufacturer.
Here are some of the tips that you can use when looking for the best overhead power line fitting manufacturer in China.
You should consider choosing an overhead power line manufacturer who is more experienced in the field of power line accessories.
The more the experience, the higher the chances of getting quality power line fittings.
Before you get into deep engagement with the manufacturer, confirm the number of years that they have been in the business.
This is another way of proving whether the manufacturer can be trusted to produce the fittings or not.
You only need to gather information from other buyers who have bought the power line fittings from the manufacturer.
This information can be obtained from the manufacturer’s website or other online marketplaces such as Alibaba.
If many buyers are expressing positive reviews about the product, then you should consider buying the equipment
On the other hand, you should tread with care if the manufacturer has quite a good number of negative reviews.
You should not ignore the production capacity of the overhead hardware manufacturer. Is the company capable of meeting your needs?
This is vital especially if you want to buy power line hardware in bulk.
One way of assessing the production capacity is checking whether the manufacturer has the right equipment and manpower to fulfil the demand for the accessories.
