Which is the best electrical insulator? It may be wood, porcelain or polymer materials. Electrical insulator is a material for supporting and insulating and may protect something.

How many types of best electrical insulator
◆ Porcelain insulators
◆ Glass insulators
◆ Polymer insulators
◆ Plastic insulator
◆ Wood T-post insulator etc.

Porcelain insulator may be the best electrical insulator, because of
◆ Long service life time
◆ Natural materials
◆ Cannot destroyed by animals
◆ Excellent mechanical strength

Polymer insulator may be the best electrical insulator, because of
◆ Light weight
◆ Manufacturing process simply
◆ Easy to install

Glass insulator may be the best electrical insulator, because of
◆ High mechanical strength, not easy cracks
◆ Used lower temperature areas
◆ Without the zero detecting

Different position used suitable electrical insulators, insulator play its own role is the best electrical insulator.
