The warning ball for high voltage lines is a visual anti-aircraft protection for overhead wires and OPGW wires in high voltage transmission lines. The ball is designed in a grooved shape while keeping the weight low, which gives it good resistance and natural stiffness. Its silicon jaws are interchangeable and fit any type of saw, allowing the two components to be stored independently.

The type of material used to make the ball prevents damage to the cable, which facilitates
the installation process. It can also stand independently with a jaw that adapts to any type and diameter of cable. The balls are directly dyed in the mass during production, they come in three available color variants (white, orange and red). They are characterized by resistance to UV radiation, and the production process allows them to last longer.
