Porcelain insulator types

Porcelain insulator

Compared to polymer insulator, porcelain insulator types have some advantages:
◆ Inherently free from both radio and television interference without any additional treatment
◆ Long service life time
◆ Natural materials
◆ Not polluted the environment
◆ Cannot destroyed by animals

Compared with composite insulators, porcelain insulator types have some disadvantages:
◆ Higher costs than composite insulators
◆ Some high voltage insulators cannot manufactured due to constraints, such as technical and heavy weight
◆ Heavier weight

Porcelain insulator types have main types used on power lines and stations
◆ T & D Line insulators
◆ Pole line insulators
◆ Station post insulators
◆ Transformer bushings

Porcelain insulator types made of porcelain materials with no defects on the surface. Most of porcelain insulator types should be glazed for excellent performance.
