If you pay attention to most power lines, you will realize some big colored aerial sphere marker balls that hang along the length of these power lines. These are power line marker balls which warn low-flying aircraft so as not to ruin them.
For one to protect the power lines and other valuable property from low flying aircraft, they will need to use these power line balls. Additionally, the same balls could be used on guy wires and communication lines as well.
Power line marker balls are made of Fiberglass reinforced plastics which have a diameter of about 600mm and 800mm all designed to meet customer's needs. The diameter should, however, not be below 600mm.
The power balls could be of different colors; that are white, orange or red. However, a single power ball is constructed to have only one solid color.
The color that is chosen for a particular power line is determined by the background against which it is seen. In this case, the color chosen should contrast with the background and thus help ensure security.
Our power balls are made up of two hemispheres, both of which have aluminum alloy clamps. These clamps are designed to fit the preferences, needs and the wire dimensions of the customer.
Each of these hemispheres has a drainage system which helps prevent water from accumulating inside the sphere as this would cause more harm than good.
Have a diameter of about 1/4inches and 5/16 inches.
The weight of the power line marker ball is about 17 pounds each. These helps ensure that the weight is not too much for the power lines they are reflecting to bear.
They come in three primary colors, orange, white and red. The three are among the most reflective colors and allow the pilot to stop them even from a far.
During installation, they have a gap of about 200-foot between them; that is between one power ball and another. The distance is put that way also as a way to enhance visibility.
They are installed in the highest wire among all those that they are expected to make visible
They use an alternate color theme to help provide clear visibility without hindrances from the background. In case the color used in one spot is white, the next color will be orange and later red.
They allow wire sag of about 25 feet to help the wires expand and contract in case of a temperature change. This way, they never are violate the sag requirements of the wires that they are marking.
Have a conductor diameter of 6.5- 5.5 mm
Visibility distance for the power line marker balls is 1200m. From this far, anyone can tell that there is a power line or communication line that they need to evade and know the course to take.
Have a voltage range of about 35KV- 1000KV
There are some drain holes in the sphere which help get rid of water in the power line marker balls. Having water remain in the balls would make them heavy which will overload the wires and even make them fall.
Have a cable clamp which is made up of aluminum alloy

Drain holes structure can prevent accumulated rainwater inside the spheres. Accumulated water will increase the weight of the marker balls which will be dangerous to the power lines.
Optional Reflective tape is more durable and economical solution for night visibility
Both sphere diameters of 600mm and 800mm are available. This all depend on the preferences or budget of the customer.
Various size of cable clamps are available to fit for customers’ cable conductor
Aluminum alloy cable clamp guarantees good corrosion resistance. There can be no cases of electrical faults due to the marker balls.
Fiberglass Reinforced Polymer durable material with better weather resistant. They can thus withstand any weather condition without affecting their structure.
Optional Reflective tape is more durable and economical solution for night visibility
Super corrosion resistant character, stainless steel bolts, and nuts
Power line marker balls have different applications and can be used in various areas. Some of these are such as:
Can be used with gay line cables as well as communication lines. You can also use these power line marker balls in other places such as warning planes about existing wires
Power line marker balls are also great for use in high power transition lines
Important in protecting electrical infrastructure from airplanes especially when flying low
Act as a guide pilots at a particular place where they can land. After seeing the power lines balls, the pilot can tell whether or not they are close the place where they intended to land.
More often than not, you will find these balls in areas which are away from cities and towns. This is the areas where there is nothing much to show the pilot that there is a power line ahead.
This is because the skyline and the conductor become invisible to the pilots when they are against the terrain.
They are an aerial warning that the power lines are there.
Package
When packing power line marker balls, we always ensure that we do it in the best way possible to ensure that they are safe as we deliver them. More often than not, the power line marker balls are distributed from Shanghai port.
Delivery
We ensure safe transportation of your order to make sure that there are no damages by the time the order reaches you. They are delivered to you in about 15 to 30 days after you order and day for the products.
Do the products have a warranty period? If yes, how long is it?
We do offer warranties for power line marker balls. However, their warranty periods differ depending on the category of the product.
What are the payment terms for power line marker balls?
We accept many forms of payment for these products. However, the most common is either PayPal or western union
What is the MOQ of the products?
We can accept I piece after the first order
Is it possible to affix the product according to the buyer’s brand?
In case the customer requests for this, we do stick the customers brand in accordance with their will.
What is the delivery time for the products?
The time we take to deliver your order is about seven working days. This is, however, in relation to the time that you made your payment.
Despite being the most convenient method of transport in several cases, air transport is also the riskiest if one is one careful. For this reason, ways such as the installation of power line marker balls have been used to make it safer and more comfortable for pilots when they come across power lines or communication lines.
