Line post porcelain insulator is permanently mounted on the metal base, it is one insulator is made up of one or more insulating elements rigidly. Sometimes, the insulating elements have a cap. Line post porcelain insulator can mounted on a support structure by bolts mounting in the metal base.
With the developing of technology, Line post porcelain insulator is appearing. This insulator has a solid insulator, it belong to A-type insulators. Thus we do not have to worry about the insulator will be breakdown in operation.
Line post porcelain insulator still has some good features, such as:
the good feature of insulation,
climate change
heat resistance,
assembly flexible.
Non-puncture type
According to the appearance, Line post porcelain insulator can be divided into vertical tie-top type, vertical clamp-top type, horizontal cup-base type and horizontal gain-base type.
