Composite insulator metal attachment
A metal attachment is a device that forms a composite insulator that is connected to a support structure, a wire, a portion of the device, or another insulator.
Connection area
A section that transfers load between the mandrel and the metal attachment.
Connection
The joint is part of a metal attachment that allows the load to be transferred from the external attachment to the composite insulator.
Trace
The scratch is an irreversible deterioration phenomenon formed by the formation of a channel on the surface of the insulating material, which is electrically conductive even under dry conditions. The scratches can be produced on the surface in contact with the air or on the interface between the different insulating materials.
